How much state ownership do hybrid firms need for better performance?

Hybrid ownership—sharing partial business ownership with the state—is a new form of political connections that entrepreneurs in developing countries may employ to improve their access to key resources. This study investigates hybrid ownership as a strategic decision of entrepreneurs running small businesses in Vietnam—a transition economy. Utilising the resource dependence theory and legitimacy viewpoint, we propose and evidently show that increased state ownership in hybrid firms leads to improved performance. However, increasing state ownership beyond a minority share threshold harms firm performance due to the presence of agency costs. Also, the involvement of the state in firm governance reduces the benefits gained from having state ownership. Is the more the better? How much state ownership really matters for hybrid firms to enhance their performance? More state ownership means more access to resources and privileges; but too much state ownership may reduce firm efficiency due to its poor governance. Analysing more than one million observations of small businesses in Vietnam, this study offers three insightful implications. First, for academics, institutional conditions should be considered when investigating political connections, especially in an emerging market context. Second, for practitioners, political connections in the form of hybrid ownership when being held at an adequate level can boost firm performance. However, an exceeding level of state ownership in hybrid firms may become harmful. Third, for policymakers, we suggest that forming hybrid business ownership with the private sector helps firms make use of state-owned resources. This collaboration is a win-win solution as long as the state ownership remains at an adequate level.

emerging markets where their institutional conditions and legal issues are not fully developed, more complex and/or incomplete (Wang, Zhang, Xu, & Shu, 2018;Wong & Hooy, 2018;Zhou, 2013). Given these institutional weaknesses in developing countries, key strategic resources such as regulation favours, information, government subsidies and bank loans are largely controlled by the state (Aidis, Estrin, & Mickiewicz, 2008;Ding et al., 2018;Du et al., 2015). In such an environment, entrepreneurs running small private businesses must build political connections with the government.
Given how topical political connections are, a vibrant research theme emerges in the literature (Sharma et al., 2020;Wang et al., 2018;Wong & Hooy, 2018;Zhou, 2017). Many authors have focused on the bright side of political connection establishments such as government subsidies, bank loans, direct contracts, tax breaks as well as their effects on firm value and performance (Feng et al., 2015;Johnson & Mitton, 2003;Li, Meng, Wang, & Zhou, 2008;Wang et al., 2018). Others find it important and useful to build political connections in order to gain access to the resources needed for their venturing activities (Zhou, 2013;Zhou, 2017). However, some authors have highlighted the dark side of political connections by showing that such connections create no value for firms (Fisman et al., 2012).
Despite progress, several important gaps need to be addressed. First, the impact of political connections on firm value and performance is found to be mixed despite scholarly efforts (Sharma et al., 2020;Wang et al., 2018). Second, the literature examining the benefits of political connections has focused on networking connections at the individual level, such as Guanxi, with local authorities. 1 This type of connection is informal, thereby being unreliable (Bian, 2017). Less frequently examined is political connections at the organisational level (Song et al., 2015), where entrepreneurs establish an institutionalised relationship with the government through an explicit, written, legal contract, which allows them to secure access to resources. This gap may limit our understanding of the important consequences of firm-level political ties on new ventures.
Also, political connections have been rarely investigated out of the context of China. We fill in this gap by focusing on Vietnam-an emerging market, which is characterised by its institutional complexity with its mixed economic model that entails both socialist and market economy traits. Vietnam therefore provides a perfect context for exploring the effects of political connections on firm performance because this institutional complexity may influence how affiliated firms establish their political connections with the government. However, we know relatively little about this phenomenon in this context. Taken as a whole, more research is needed not only on scholarly insight into this phenomenon and its consequences, but also on theorising how political connections influence firm performance in a unique context such as Vietnam.
Specifically, in this study we ask: (1) whether state ownership is essential and beneficial for hybrid firms? and (2) if so, how much they actually need to increase their performance? We hypothesise that as state ownership increases, hybrid firms gain more access to resources controlled by the state and become more legitimate in the eyes of stakeholders. These effects enhance firm performance via increased business opportunities and financial leverage. However, this process also implies that entrepreneurs in hybrid firms must trade off their control rights over the governance of the business against improved access to resources and legitimacy. As such, due to the agency costs associated with state ownership, governance efficiency reduces sharply as state ownership increases significantly (Du et al., 2014;O'Toole, Morgenroth, & Ha, 2016), leading to a reduction in firm performance. This is consistent with the situation of state-owned firms, whose privileges fail to improve their performance because of agency problems.
Empirically, employing a fixed-effect method for panel data of Vietnam's small businesses over the period from 2006 to 2018 with appropriate controls for potential endogeneity and multi-level structure of the dataset, we find that when hybrid firms increase state ownership, they become less sensitive to bureaucratic harassments, leading to improved performance. However, increasing state ownership beyond the 50% threshold harms firm performance.
Our contribution is fourfold. First, our study contributes to the literature on strategic entrepreneurship by providing a broadened view on political relationship building by small businesses in developing countries. While the majority of studies have focused on the benefits of political connections, our study focuses on the dark side of political embeddedness. Specifically, we suggest that an appropriate level of state ownership helps boost hybrid firm performance; however, an excessive level of state ownership may be harmful. This study therefore sheds new light on the dark side of political connections that add no value to firms (Fisman et al., 2012). Second, this study is among the first to examine political relationship building from the viewpoint of organisational strategy rather than individual informal networking.
Third, this study contributes to the literature by examining the establishment and evolution of the entrepreneurial sector-private small and young businesses (Du & Mickiewicz, 2016) in Vietnam. It expands the context of analysis of political affiliated businesses out of the conventional empirical settings of China and focuses on the fast-developing but unexplored context of Vietnam. Given the mixed nature of institutions between socialist ideologies and market-based principles (Awaworyi Churchill, Munyanyi, Smyth, & Trinh, 2020), the literature has highlighted that small and young firms in Vietnam need to employ unique strategies to "play the institutional game" and gain access to key resources, which are under the control of the state. This study suggests that sharing ownership with the government could be a feasible but unexplored strategy.
Finally, this study has insightful implications for entrepreneurs in Vietnam in specific and developing countries in general. While it is beneficial to share equity ownership with the state in less developed institutional environments, entrepreneurs need to retain control of their business governance. Such a strategy would help small firms gain access to key resources and obtain legitimacy while still remaining efficient and performance-driven.

Institutional background of Vietnam
Scholars have recently highlighted the vital importance of the context in theorising and understanding its influence on entrepreneurial environments (Welter, 2011;Welter & Baker, 2020). This is important because there is often a close interaction between entrepreneurs and their business environments over time to construct and enact the places in which they are embedded (Welter & Baker, 2020). In today's increasingly global business environment, the context/place may become even more important because it is a decisive factor that may enable us to record all sorts of potential complicated differences in contexts such as between different countries that may influence entrepreneurial identities and actions (Welter & Baker, 2020). Taking the context into account will provide us with more opportunities to advance our theories by choosing different viewpoints to approach a research topic (Welter & Baker, 2020).
Specifically, we decided to choose Vietnam as a unique and interesting context for this study for several reasons. First, Vietnam is known as its mixture of socialist-and capitalist-orientated economy (Do et al., 2020), thereby being especially unique in comparison with other countries. As a post-communist economy, the Vietnamese government is still the key player of the whole national economy, and thus controls most of the country's key strategic resources, including financial markets and land use rights (Nguyen, Mickiewicz, & Du, 2018). Second, the institutional arrangements of the country remain biased heavily toward the state sector (Nguyen & van Dijk, 2012). Entrepreneurs must therefore put significant effort into building political relationships in order for their ventures to survive and grow. Khuong (2015), in a comparison of the economic reforms in Vietnam and China, suggests that Vietnam remains less open to the private sector than China; leading to a situation in which entrepreneurs in Vietnam need to exert more effort than entrepreneurs in China to gain access to key resources.
Third, Vietnam is an emerging economy characterised by the booming of the entrepreneurial sector (young and small private businesses). Such firms are the key driver of Vietnam's phenomenal economic transformation over the last decade . In particular, Tran (2019) offers a discussion of the economic transition process in Vietnam and explains that the liberalisation phase of reforms was only achieved from the year 2000 onwards. This is why the population of private firms is very young, with an average firm age in our sample is 6.2 years. The smallness and youngness of most private firms in Vietnam imply that they need to build up political connections, including sharing ownership with the government, to gain access to resources for survival and growth. Taken together, the institutional conditions exert a profound influence on the establishment of Vietnamese firms and their ownership structure. This study therefore contributes to theory by contextualising entrepreneurship scholarship that is often criticised for not having paid enough attention to the theorisation of context (Welter & Baker, 2020).

Institutional incompleteness and hybrid entrepreneurship
In weak institutional environments (e.g., developing economies), key strategic resources such as capital, land, information, technology, and human resources are controlled by the state (Nguyen, 2019). In such a constrained situation, firms often actively engage in purposeful political activities to secure access to these resources and reduce the impacts of institutional uncertainty (Ding et al., 2018;Zhou, 2013). Firms may engage in several forms of political activities. One strategy is to create social connections, which is where entrepreneurs actively strive to build their social capital and create political connections by entertaining and giving gifts to local authorities in their social networks (Bian, 2018;Luo et al., 2012). In the context of China, this strategy has been found to improve firms' access to external financing (shortterm debts) (Du et al., 2015). Along the same lines, entrepreneurs may actively enhance their political status (Faccio, 2010;Goldman, Rocholl, & So, 2009) or exploit the political status of people in their personal networks, including their father, mother, spouse, adult children, other intimate relatives, and close friends. This strategy also has been found to be positively related to entrepreneurial investment in the context of China (Zhou, 2013). While the majority of the literature is concerned with political connections at the personal level, only a little research focuses on political connections at the institutional level (Song, Nahm, & Yang, 2016). The latter strategy-conducted by so-called government-private hybrid firms-takes the form of an explicit, written, legal contract, based upon which entrepreneurial firms build a formal connection with the government. There are three typical connection types. In the "red-hat" type of firm, a private entrepreneur gets permission from a government agency to register her business as a de jure government-owned firm. The firm then pays an annual "management fee" to the government while operating as a normal private business (Chen, 2015;Peng, Lu, Shenkar, & Wang, 2001). In the "rented" type of firm, a private entrepreneur rents a government-owned firm on a longterm basis following one-to-one bargaining with the government. The entrepreneur has full control over the governance and operation (but not ownership) of the firm, but once again, he/she must share residual income streams with the government (Lipton, Sachs, & Summers, 1990;Megginson & Netter, 2001).
Both of these hybrid firms, though de facto private, are legally owned by the government, and they were quite popular in China, Vietnam, and Eastern European countries in 1980s and 1990s (Chen, 2015;Lipton et al., 1990;Walder & Nguyen, 2008). However, their numbers have reduced significantly over the last decade (Zhou, 2017), leaving room for the emergence of the third type of hybrid form-mixed ownership. 2 Mixed ownership hybrid firms are those businesses whose shares are owned by both private entrepreneurs and the government (Song et al., 2015). Technically speaking, the shares owned by the government in this type of firm could be any percentage, as long as it is not zero percent (i.e., private firms) or one hundred percent (i.e., state-owned firms). This type of hybrid firm is becoming more and more popular as privatisation increases in post-communist economies (Song, Nahm, & Zhang, 2017). However, there is hardly any research that systematically examines mixed ownership hybrid firms from the strategic entrepreneurship viewpoint. As such, unlike the strand of research that investigates the economic consequences of privatised large corporations (see Divya Verma & Abhijit, 2018 for a review), we focus on the strategies employed by entrepreneurs aimed at establishing political affiliation via the route of sharing their (small) businesses' ownership with the government. The literature is as yet silent about how effective this strategy is at coping with institutional voids. This study fills that gap.

Hybrid firms, private firms, and state-owned firms
In weak institutional environments, both private and state-owned firms have their specific shortcomings and disadvantages. Private firms are typically discriminated against by the legislative systems (Allen et al., 2005;Boudreaux & Nikolaev, 2019) and the financial markets (Allen et al., 2005;Guariglia & Liu, 2014), both of which are in place primarily to support state-owned firms (Du et al., 2015). In the context of Vietnam, for example, it is found that private firms have limited access to land and landuse rights, operation permits, bank loans, and financial subsidies in comparison with state-owned firms (Malesky, McCulloch, & Nhat, 2015;Nguyen, 2019;Nguyen, Le, & Freeman, 2006). Thus, private firms are restricted from leveraging resources. Meanwhile, state-owned firms, even though their access to key strategic resources is unhindered, may fail to utilise these resources effectively to maximise profits due to agency problems associated with the manager-owner governance system (Liu, Zhang, Fang, & Chen, 2021), which prevent them from operating an efficient system of corporate governance. In this regard, the establishment of mixed ownership hybrid firms, in accordance with resource dependence theory (RDT) (Pfeffer & Salancik, 1978), may be a solution. Specifically, RDT proposes that resources are key to organisational success and that access to and control over resources is a source of power. As such, entrepreneurs are incentivised to increase their acquisition and control over resources through a set of strategies that includes sharing ownership of the business with the government (i.e., the owner of the resources). In this way, hybrid firms, thanks to their partial state ownership, can obtain access to crucial resources controlled by the state (Zhou, 2017). Some empirical evidence has initially supported this argument. For instance, in a series of studies on mixed ownership in publicly listed firms in China, Song and colleagues show that hybrid corporates gain more access to bank loans, credits, and operation permits in industries to which formal barriers restrict entry (Song et al., 2016;Song et al., 2015;Song et al., 2017). Also, Chinese politically affiliated firms are more likely to engage in productive activities to improve earnings (Zhou, 2014) as well as in risktaking behaviours (Ding, Jia, Qu, & Wu, 2015) than non-affiliated counterparts. Therefore, hybrid ownership-a firm-level strategic approach to political affiliation-is expected to improve firm performance.
In addition to access to resources, mixed ownership may help hybrid firms gain legitimacy in their local business environment. Legitimacy is "a generalised perception or assumption that the actions of an entity are desirable, proper, or appropriate within some socially constructed system of norms, values, beliefs, and definitions" (Suchman, 1995, p. 574). Hence, once a firm has legally obtained a hybrid form, it may utilise the signalling effect to send a positive message about its credentials to stakeholders, strengthening its market position. Also, being a "legitimate business" in an institutional environment that shows favouritism to state-owned enterprise may help hybrid firms to avoid, to some extent, harassments such as corruption and bureaucracy (Kuratko, Fisher, Bloodgood, & Hornsby, 2017). Some initial empirical evidence has confirmed this line of argument. For example, Li, Chen, Gao, and Xie (2019) find that obtaining government R&D subsidies has a certification effect, which is used by Chinese entrepreneurial firms as a legitimation strategy to access bank finance. Furthermore, Cheng, Chan, and Leung (2018) suggest that Guanxi-related perks play an essential marketing role in enhancing long-term success. Meanwhile, in Vietnam, evidence shows that the frequency of interaction with public officials is negatively associated with bribe values (Rand & Tarp, 2012) and positively associated with the duration of bank loans (Pham & Talavera, 2018).
In short, we propose that hybrid firms may gain more competitive advantages than their private counterparts. These competitive advantages come from (1) access to key strategic resources, and (2) improved legitimacy. Meanwhile, hybrid firms may be more efficient than state-owned firms in utilising resources because they face fewer owner-manager agency problems (Liu et al., 2021). As such, we draw upon the RDT and legitimacy viewpoint to highlight the importance of hybrid firms' capacity to gain access to external resources and establish their legitimacy, leading to improved performance ultimately. We propose the following: Hypothesis H1: There is an association between firm ownership structure and firm performance.

Hybrid ownership and performance
While it is argued that hybrid firms perform better than their private and state-owned counterparts, we suspect that, within the group of hybrid firms, there is substantial heterogeneity in performance, depending on the proportion of state ownership. Specifically, we expect that when state ownership is at a minor level, an increase in state ownership will foster firm performance. However, an excessive level of state ownership may be harmful.
In accordance with the general corporate governance principles, a shareholder or a group of shareholders holding more than 50% of equity shares of a firm can take over the power of governance or appoint a representative to do so, unless otherwise agreed with the minor shareholders (Tricker, 2015). As such, when state ownership in a hybrid firm exceeds 50%, it is the state (aka the government official appointed to represent the state) rather than the entrepreneur who makes the final decisions on firm governance and development strategies. We now turn to discussing two cases: (1) when state ownership is minor, and (2) when state ownership is major.

When state ownership is less than 50%
When the state plays as a minor owner in hybrid firms, by laws, the appointed officials representing the state do not have the right to make the final decision regarding firm operations and strategies. Entrepreneurs who hold the majority of the shares have the right to do so. At this stage, an increase in state ownership (as long as it does not exceed 50%) will bring about benefits for hybrid firms in terms of both enhanced legitimacy and more access to external resources, in turn leading to improved performance.
The RDT holds that external resources affect behaviours of organisations and that organisations could strategically make use of external resources to improve their performance (Pfeffer & Salancik, 1978). In the context of hybrid firms, when state ownership increases, the state can take a higher proportion of dividends (profits) from the firms. As such, the state becomes more willing to grant support and offer special treatments to such firms. This support could be in the form of business opportunities. Although the extant literature does not offer direct evidence comparing access to business opportunities between hybrid firms having different degrees of state ownership, we do find some evidence showing that stateowned or state-affiliated private firms are offered more and better business opportunities.
For example, in their study of almost 2 million firm observations in the private and state sectors in China over the period of 1988of -2007of , Du et al. (2014 find strong and consistent evidence of systematically uneven business opportunities between the two sectors. Additionally, Sharma et al. (2020) highlight that political connections exert a significant positive effect on Chinese firms' decisions to enter export markets and on their subsequent export performance. They suggest that non-market forces allow opportunities to be diverted away from allocation by the competitive market and towards the state sector. Moreover, due to their improved access to information and government support, hybrid firms may be in a better position than private firms to realise business opportunities, thereby being able to make more investments. In Vietnam, for example, Van Thang and Freeman (2009) examine 16,200 firms and evidently show that the greater the density of state-owned firms in a region is, the more favouritism they enjoy, thereby reducing the proportion of bank loans made to private companies and increasing the time it takes private firms to gain access to land.
On the basis of the above, we extend the RDT with regard to access to finance to explain why increased state ownership is positively associated with firm performance. When state ownership increases, the benefits/losses that the state obtained from hybrid firms become more significant; as such, the state has a stronger incentive to help enhance firm performance, including granting them access to external finance. Research has shown that firms having a close connection with the government enjoy better treatments in terms of bank loans (Du et al., 2015;Nguyen et al., 2006;Song et al., 2017;Van Thang & Freeman, 2009). This strand of literature points to the possibility that when the state has a larger stake in hybrid firms (but remains less than 50%, we will discuss the case of larger than 50% in the next section), the state is more willing to give hybrid firms more business opportunities and access to finance. These additional resources under the management and governance of entrepreneurs, who hold the majority shares of the firms, could lead to improved performance.
When state ownership increases, hybrid firms can not only obtain more sources from the governments, but can also utilise their enhanced legitimate identity to acquire opportunities from markets. Legitimacy is an essential dimension in the institutional theory, which highlights the importance of being socially accepted (e.g., credibility) to firm survival and growth (Suchman, 1995). In the context of hybrid firms, their government-backed identity may persuade and enable clients and suppliers of their credibility to sign longer-term or higher-value contracts. For example, firms that have state ownership of 40% may find it easier to signal business partners that they are backed by the governments than those whose state ownership only makes up 10%. Also, when state ownership increases, hybrid firms may deploy their enhanced hybrid identity as a valuable asset to improve their market position and gain trust from stakeholders, in turn leading to stronger alliance relationships. In support, Chase and Murtha (2019) show that US firms that have at least one contract with a government agency, thanks to the signalling effect, are more likely to enter into further contracts with other government agencies and also with private clients. Moreover, hybrid firms may utilise their legitimacy to gain access to trade credits and informal loans. It is also noteworthy that larger state ownership indicates stronger commitment that the state puts into the hybrid firms. This has a signalling effect, which is able to reduce information asymmetries between firms and external potential resource holders, and thus facilitate firms' access to external finance (Li et al., 2019), including trade credits (Agostino & Trivieri, 2014) and informal debts (Reynolds, 2011).
In light of the RDT and legitimacy viewpoint, it could be expected that when state ownership increases, hybrid firms gain more access to business opportunities, external finance, and enhanced legitimacy. Such essential ingredients will likely enable hybrid firms to improve their performance.

When state ownership is more than 50%
While we argue that increases in state ownership are positively associated with improved performance of hybrid firms, we suspect that this relationship is non-monotonic. It is therefore argued that an excessive level of state ownership may be harmful to firm performance. The reason lies in the negative effects associated with agency problems when the share of state ownership becomes too large. Specifically, when state ownership in a hybrid firm exceeds 50%, it is the state rather than the entrepreneur who makes all decisions for the firm. In this situation, firm performance may not be as good as it is when state ownership remains below 50%. This happens because of agency problems.
The first agency problem occurs between entrepreneurs and the state. Specifically, entrepreneurs who are minority shareholders compared to the state receive a smaller proportion of distributed profits earned from running the business. This fact makes entrepreneurs less motivated to contribute to higher performance and success of the firm. This agency problem inevitably leads to deficient outcomes (Wehrheim, Dalay, Fosfuri, & Helmers, 2020) because entrepreneurs' contributions are the main driver of firm performance (Song et al., 2015). The second agency problem, which is well-documented in the extant literature, occurs between a government official running a hybrid firm and the state. The government official may extract private benefits from running the firm instead of maximising its profits or share values. This opportunistic behaviour exists because of the incompleteness in the monitoring systems of the state (O'Toole et al., 2016) and the government official's lack of professional management skills, given that he or she is often appointed by the administration (Gan, Guo, & Xu, 2017). With the majority of ownership, the stake of the state in hybrid firms is relatively large. In the presence of weak institutions, the government officials are therefore relatively free to extract private benefits from running the firms. Taking altogether, we propose the following hypothesis: Hypothesis H2: For hybrid firms, the association between state ownership and firm performance follows a non-linear pattern.

Local governance quality and state governance
In this section, we focus on the association between hybrid ownership and firm performance in relation to institutional settings. The first institutional dimension of investigation is local governance quality; and the second is the intervention of the government in hybrid firms.

Local governance quality
Local governance quality-a dimension of institutions-indicates the execution and implementation of national legislation and other formal institutional arrangements at the local (e.g., provincial) level . Specifically, Williamson (2000) argues that the play of the game (the execution of formal institutions) is even more important than the rules of the game (the formal institutional framework per se) because no rule of law can become effective in practice unless backed up by a set of efficient governance systems.
In the context of Vietnam, the quality of governance across regions varies significantly due to the impact of the nation's history (Mirza & Giroud, 2004). While in North Vietnam, the institutions were initially built following the pure socialist blueprint, South Vietnam only transformed from capitalism in 1975. This historical event contributes significantly to the differences in local institutions of governance across regions of Vietnam (Makino & Tsang, 2011). Moreover, these institutions of governance are rather sticky despite the unification of the two states four decades ago, which instituted a single formal framework across the nation .
In addition, the variations in local governance quality have been magnified due to the extensive decentralisation in the Doimoi (economic renovation) (Lan Phi & Anwar, 2011). The foundation of this program was the promulgation of the 1996 (revision in 1998) State Budget Law, which grants local governments sufficient autonomy in their fiscal strategies. Local authorities are considerably independent of the central government in their revenue and expenditure decisions. Further to this, they have substantial freedom to determine their local regulatory arrangements, which create substantial heterogeneity in the governance quality across regions in Vietnam (Anwar & Nguyen, 2014;Schmitz et al., 2015).
Meanwhile, local governance quality is crucial to small firms because these firms typically operate within the boundary of local markets, which are strongly shaped by the governance arrangements of local authorities rather than the very broad general national institutions (Du & Mickiewicz, 2016;Nguyen & Canh, 2020). In this regard, hybrid ownership may serve as a strategic political connection that helps firms build relationships with local authorities.
In a biased institutional environment (i.e., one that is geared towards benefiting state-owned enterprises) gaining legitimacy (i.e., being treated as a (partial) state-owned firm) is particularly essential to ensure that firms are exempted from corruption and unproductive interventions from government agencies, or even to allow them to enjoy favourable treatments from local authorities.
Empirical evidence suggests that firms with a strong political affiliation (i) experience better de facto protection of their private properties (Zhou, 2017), (ii) are less sensitive to corruption (Nguyen & van Dijk, 2012), and (iii) are exempted from bureaucratic interventions from local government agencies (Nguyen, 2019). Therefore, it could be expected that when local governance quality is lower, the effect of state ownership on protecting firms against corruption and bureaucratic governance becomes stronger. In contrast, when local governance quality is higher (more effective), the effect of state ownership becomes less substantial since firms in all sectors have a fair access to information, opportunities, and resources. This strand of arguments points to the possibility that state ownership may substitute the effects of improved governance quality. As such, we hypothesise: Hypothesis H3a: Local governance quality moderates the association between state ownership in hybrid firms and their performance.

The involvement of the state
In this section, we argue that the break in governance efficiency may happen even before state ownership reaches 50% if the government is allowed to become involved in the governance of hybrid firms. This can occur when entrepreneurs who own the majority (greater than 50%) of equity shares of a hybrid firm decide to let the government (in this case, the minor shareholder) become involved in business governance. The purpose of this decision is to further enhance their political affiliation status and improve firm legitimacy with a view to gaining additional preferential treatments such as subsidies and lower tax rates (Du et al., 2015). In this regard, the state (the government official appointed to represent the state) instead of the entrepreneur has the final voice in the governance of the firm. This arrangement, unfortunately, may have a negative impact on firm performance for several reasons.
First, appointed officials may not possess adequate skills in governance and management of business operations needed to do their jobs. Unlike entrepreneurs who need to build their business from scratch, the appointed officials usually hold their positions in the public administration system before being appointed to a business . As such, they tend to employ the governance style of running a unit of government agency to the business, which may not work well for business activities. Second, the appointment is term-based, which typically lasts 5 years before the official being rotated to another position in a different organisation (Lan Phi & Anwar, 2011). Since the officials are not in charge of their performance outcomes after the appointment term, they are not incentivised to maximise firm long-term value but are more likely to concentrate on extracting rents from running the firm. This agency cost, which originated from the nature of the appointment system, reinforces our argument that the involvement of the government in the governance of hybrid firms may reduce firm performance.
More importantly, the involvement of the government may further deteriorate the benefit associated with state ownership in a hybrid firm. It is noteworthy that the benefit associated with state ownership is primarily the firm's access to key strategic resources owned by the state. However, the appointed official may fail to build a system of efficient governance to utilise these resources. For example, the governance system under the leadership of the appointed official may be distracted from pursuing economic goals (but political goals, for example), or may be inefficient in transforming resources into competitive advantages (due to the lack of managerial skills or the rent-seeking behaviours) (Du & Girma, 2012;Nguyen, 2019). This unproductive governance system is thus expected to reduce the positive impacts of additional resources obtained from state ownership on firm performance. In support, Song et al. (2015) evidently show that in Chinese listed hybrid corporates, the positive impact of state ownership on firm performance becomes less prominent when the corporate governance is more politically inclined. Also, in the context of Vietnam, De Jong et al. (2012) show that although political connections allow firms to foster a network of informal relationships with public officials, and reap the accompanying benefits, they may have such disadvantages as an inefficient allocation of resources, which leads to reduced firm performance. As such, we propose: Hypothesis H3b: For hybrid firms that have a percentage of state ownership that is less than 50%, there is an association between the involvement of the government in firm governance and firm performance. Hypothesis H3c: For hybrid firms that have a percentage of state ownership that is less than 50%, the involvement of the government in firm governance moderates the association between state ownership and firm performance.
Before introducing the data for analysis and the empirical estimations, we summarise the proposed hypotheses in Fig. 1.

Data
The empirical setting of this study is Vietnam-a transition economy. The country has a large number of small and very small firms (e.g., household businesses) operating in an underdeveloped and incomplete institutional environment (Nguyen & Canh, 2020;Tran, 2019) that fits well into the theoretical settings of this study. To test the proposed hypotheses, we employ the Annual Enterprise Survey (AES) dataset provided by the Vietnam General Statistics Office (GSO). The survey was first conducted in 2000, and the dataset has been updated annually since then. By the statistics regulation of Vietnam, all businesses having more than 10 employees must take part in the survey. For businesses with fewer than 10 employees, a sample is randomly selected to participate in the survey. The scope of the survey comprises both manufacturing and service industries, and includes all types of ownership, including private, state-owned, hybrid, and foreign-owned.
The AES panel data that we obtained from GSO is 19 years, from 2000 to 2018. However, the period of analysis in this study is unfortunately scaled down to 13 years, from 2006 to 2018. The reason is that: first, it is only from 2006 that the information about hybrid ownership is fully reported; second, the data must match with the second dataset taken from the Provincial Competitiveness Index (CPI), a joint product of the Vietnam Chamber of Commerce (VCCI) and the US Agency for International Development (USAID). PCI is a panel of provincial governance quality. The quality index is scored from 0 to 100, and the higher score means the better quality of governance, such as corruption controls, land access, leadership proactivity, and administration transparency. The PCI index is calculated based on a survey of more than 15,000 private firms and 1500 foreign-owned firms operating across 63 provinces in Vietnam. From 2006, the PCI index has been reported for all provinces annually.
We combine the AES dataset with the PCI dataset to create a panel of 13 years. Before analysing the data, we conduct some initial cleaning to avoid biases. Specifically, we drop all observations that have meaningless accounting reports such as negative number of employees and zero assets. We control the outliers by censoring the top and bottom 1% of observations in each continuous variable. We understand that the three categories of business ownership is over-simplified since in reality, state-own firms may be owned by several branches of governments (e.g., local government vs central governments); also, private firms are a group of businesses of different legal forms (e.g., limited liability company, joint-stock company, and partnership). However, to explore the impacts of hybrid ownership, the simple model of three categories of firm ownership is arguably most appropriate. Also, we are aware that firms that have both stateowned and private ownership may be either privatised state-owned firms or hybrid firms. To reduce the possibility that the former is also included in our sample, we excluded large firms since privatised state-owned firms are usually large corporations (O'Toole et al., 2016). After doing so, we find no firms changing their ownership between private, state-owned, and hybrid in the study period. This indicates that the hybrid (small) firms under investigation are born-hybrid (i.e., not being hybrid because of privatisation). After applying these exclusions, the final sample in our study thus includes 1,093,613 firm-year observations, in which 20,633 are hybrid.

Dependent variable
The dependent variable of interest is firm performance. For the sake of robustness, we measure firm performance using two variables: revenues and profits. Revenue is a proxy for a firm's market-based performance relative to its peers in the same industry. Firms with higher market shares (i.e., more revenues) enjoy several competitive advantages, such as better brand recognition, higher brand values, more business opportunities, and stronger market powers (Diewert & Nakamura, 2007). Profits, on the other hand, represent the efficiency of firm governance. Firms with higher profits ceteris paribus have a more efficient cost function, which could result from stronger managerial capital (Diewert & Nakamura, 2007). In this study, both revenues and profits are normalised using firm total assets.

Independent variables
The key independent variable of interest is the percentage of state ownership in hybrid firms. It is noteworthy that state ownership is a continuous variable and must be greater than 0 and smaller than 100 Fig. 1 Analytical framework. Hypothesis H1, which is not presented in the analytical framework, investigates the performance of firms based on their general ownership structures (i.e., private firms, state-owned firms, and hybrid firms) (otherwise a firm would be either private or stateowned). Hybrid firms that have less than 50% of state ownership may nevertheless decide to let the government become involved in their business governance. As such, government involvement is a dummy variable, which takes value 1 if the government takes the lead in the governance of the firm, and 0 otherwise. This information is reported by individual firms in the survey.

Control variables
Following the extant literature, we include a set of covariates that may influence firm performance. At the firm-level, we control for firm size, firm age, firm investment and industry. These variables represent firm-specific and industry-specific characteristics that significantly determine both economic performance and productivity performance (Valliere & Peterson, 2009;Zhou, 2017).
At the entrepreneur level, we control for owner age. This individual-specific factor plays an essential role in determining firm performance because it indicates the extent of the entrepreneur' experience, and to some extent, education which may markedly influence his or her ability to run a business (Nguyen, 2018). It is noteworthy that other time-invariant characteristics associated with entrepreneurs that may have influences on firm performance such as management styles and working experience before start-up will be controlled by the fixed-effects which will be introduced in the next section.
At the provincial level, we take into account the governance quality of local governments, which is measured using the PCI index. This index is a combination of nine sub-indices, each evaluating a dimension of local government, such as controls for corruption, levels of transparency in public services, and the leadership proactivity of local authorities. Details of the nine sub-indices are presented in Appendix  Table 6. The PCI score ranges from 0 to 100; the higher score means the better quality of local government. The methodology of the index is introduced in Appendix 4. In the study period, the average PCI score is 58. However, one province's score may be as low as 36, while another may achieve as high as 77. These statistics show that there is substantial heterogeneity in the quality of governance of local governments across provinces in Vietnam.
The definition and summary statistics of all variables are presented in Table 1. For the sake of comparison, we present the statistics for hybrid firms, private firms, and state-owned firms, respectively. The pairwise correlation matrix is presented in Appendix Table 7.

Specification and estimation
Based on the conventional firm performance models, we propose the following expanded reduced-form equation. This is our baseline specification: where i denotes an individual firm, g is the province, and t a year. Therefore, Performance igt is either revenues or profits that firm i in province g achieves in year t . The term Firmcontrols igt is comprised of the variables firm age, labour size, and investment; the term Ownercontrol igt is the owner age variable; and Provincecontrols gt is the PCI score.
In addition, the equation includes an industry-specific component v j and a time-specific component v t , which are controlled by corresponding dummies. The term v i represents all time-invariant, firm-specific factors that may influence firm performance. Finally, it is the idiosyncratic error.
We employ the random-effects (RE) method to compare the performance of hybrid firms, stateowned, and private firms. This is because no firms jump across the three groups in our sample. Then, we use a fixed-effects (FE) method to estimate the specifications related to the performance of hybrid firms. The FE technique is able to control for unobservable time-invariant firm-level characteristics such as management and organisational culture (Nguyen, 2019); as such, it could, to some extent, reduce concerns about endogeneity due to missing variables. Also, to moderate concerns about the reverse effects from control variables to the dependent variable (firm performance), we lag firm size and firm investment one year. Moreover, we take into account the multi-level structure of the dataset by clustering the standard errors to the provincial level as well. Finally, we also conduct the variance inflation factor (VIF) tests of multicollinearity.

Main results
Regression results are presented in Table 2 to Table 5. The VIF tests suggest there is no significant multicollinearity in our specifications. Table 2 shows the results comparing the performance of the three types of firms: private, hybrid, and state-owned. Since the sample under investigation includes only firms that do not change their ownership types between the three groups in the study period, we employ the random-effects (RE) technique to estimate the coefficients associated with state-owned firms and private firms (the group of hybrid firms was set as the benchmark). The results show that hybrid firms consistently achieve better revenues and profits (relatively to their total assets) compared to state-owned firms and private firms. Figure 2 illustrates this finding graphically. Hypotheses H1 is thus supported.
Turning to the effect of state ownership on hybrid firm performance, we move to Table 3. To facilitate the interpretation, the variable state ownership (as a percentage) is multiplied by 100. The coefficients associated with state ownership variable in columns 2 to 4 are positive and statistically significant, confirming our initial expectation that an increase of state ownership in hybrid firms boosts performance. For   Table 3). The coefficients are negative and statistically significant. This finding initially supports the inverted U-shaped relationship between state ownership and performance in hybrid firms. Using the coefficients associated with state ownership and its squared terms, we calculate the transition points, which are 87% of state ownership for revenues to start reducing and 42% of state ownership for profits accordingly. For robustness checks, we also run regressions for subsamples of hybrid firms that have less than 50% of state ownership (columns 5 and 6) and more than 50% of state ownership (columns 7 and 8). The results show that the coefficients associated with state ownership are positive and statistically significant in the specifications of state ownership that are less than 50% while they are negative or insignificant in the specifications of state ownership that are equal to or greater than 50%. To illustrate the non-monotonic effect of state ownership, we present the marginal graphs in Figure 3a (revenues) and 3b (profits). The graphs show that when state ownership is low, an increase in state ownership is positively associated with firm performance. However, when state ownership is high, its positive effect gradually disappears or even turns negative. Given these findings, hypothesis H2 is supported.
In terms of the moderating effects of local governance quality, Table 4 shows the results. The coefficients associated with the interaction term between state ownership and local governance quality are negative (columns 1 and 3) and statistically significant (column 1), indicating that the effect of state ownership and the effect of governance quality are substitutive: when local governance equality is lower, the effect of state ownership is higher. Figure 4a illustrates this relationship graphically. Specifically, when local governance quality is higher, the positive impact of state ownership on hybrid firm revenues appears less significant (the dashed line). However, when local governance quality is lower, the relationship between state ownership and revenues becomes stronger (the steeper slope of the solid line). We expect that this pattern is valid not only for the linear relationship but also for the inverted U-shaped relationship. As such, we also examine the coefficients associated with the interaction between the squared term of state ownership and local governance quality. To illustrate the effect in a more straightforward manner, we draw the marginal graph (Figure 4b).
Coupled with the linear effect, the figure shows that the inverted U-shaped relationship between state ownership and revenues in hybrid firms is stronger in weaker governance and vice versa. In terms of profits, the sign of the coefficients in columns 3 and 4 of Table 4 are consistent with those in columns 1 and 2, indicating that they follow the same pattern. However, since the coefficients are not statistically significant, we do not find strong evidence to support the moderating effects of local governance on hybrid firm profitability. A possible explanation could be that while revenues are strongly dependent on the local markets, which are a function of local governance quality, profits represent the efficiency of firm operation and management, thereby, to some extent, being under firm control and less affected by external environments. As such, hypothesis H3a is partially supported. Table 5 presents the results of the subsample of hybrid firms that have less than 50% of state ownership, some of which may have decided to allow the government to get involved in their business governance to some extent. The coefficients associated with state governance are negative and statistically significant at 10% (in columns 1 and 3). This finding suggests that the involvement of the government in firm governance may harm hybrid firm performance. Therefore, hypothesis H3b is supported (by weak evidence). Turning to the interaction terms between state ownership and state governance, their associated coefficients are negative (in columns 2 and 4) and statistically significant (in columns 2). These findings show that the involvement of the government in firm governance has a negative indirect effect on firm revenues via a reduction in the efficient use of state ownership. Since the corresponding coefficient in column 4 (profit specification) is not significant, hypothesis H3c is supported to some extent. Figure 5a and b illustrate the marginal effects of state governance on firm performance. They demonstrate that the positive impact of state ownership almost disappears if the government is involved in firm governance.
Finally, in terms of the control variables, firm size has a positive effect on economic performance but a negative  effect on productivity performance. This is consistent with a strand of research showing that large firms, due to their bureaucratic management, may lose productivity despite an increase in their revenues and profits (Ding, Guariglia, & Harris, 2016;K De & Nagaraj, 2014). The results also show that local governance quality exerts a consistently positive effect on firm performance.

Robustness check
For the sake of robustness, we also employ a panel data threshold fixed-effect regression technique (Wang, 2015) to test the significance of the inverted U-shaped relationship between state ownership and performance in hybrid firms. The results are reported in Appendix Table 8 and are consistent with our main findings. It is noteworthy that this method requires the panel dataset to be strongly balanced; the number of observations thus drop from 20,633 to 4,568 in conducting this analysis. As such, the results obtained from this robustness check cannot be directly compared with the main results presented above since the numbers of observations are different. However, the findings show that the thresholds we proposed exist and are significant, even with a small number of observations. The mean values of the thresholds are 73% (vary from 70 to 77%) of state ownership in the revenue specification and 36% (vary from 35 to 37%) of state ownership in the profit specification. These values are close to the transition points we obtained using an unbalanced panel (87% for revenues and 42% for profits).

Discussion and concluding remarks
Given that there is a lack of clarity about whether state ownership is essential and beneficial for hybrid firms and to what extent it may matter for firms to increase their performance, this study enhances our knowledge of this field by exploring the effect of state ownership on hybrid firm revenues and profitability. As Vietnam is unique with its institutional environment being biased towards state-owned firms but under-researched context, this context can provide valuable insights for political connections research. Utilising the RDT and legitimacy viewpoint, we argue that if private firms are to improve their survival and development opportunities, they must actively  Fig. 4 a Marginal effects of local governance quality on revenues (linear interaction).

State ownership is in the range of [0, 100] percent with 0 and 100 are excluded engage in purposeful political activities to control and manipulate the unfavourable environments. As such, in this study, we suggest that partnering with the state to form hybrid ownership firms is a strategic decision that allows entrepreneurial firms to gain access to key resources while legitimising their identity. Given such benefits, we find that hybrid firms perform better than their private and state-owned counterparts. However, we acknowledge that increases in state ownership are associated with increases in agency costs. Therefore, we also investigate the possibility that an excessive level of state ownership may harm firm performance. Finally, we explore how the two political affiliation strategies, i.e., hybrid ownership and having a measure of state involvement in firm governance, interact with one another and affect firm outcomes. Our findings provide empirical evidence to support the political connections literature from several perspectives: (i) political connections in the form of hybrid ownership is important to small firms operating in emerging markets such as China and Vietnam (Du et al., 2015;Song et al., 2017); and (ii) hybrid firms can increase their performance through a certain degree of state ownership; an exceeding level of state ownership may, however, become harmful. This study offers both theoretical and practical implications.

a Marginal Effects of Local Governance Quality on Revenues (Linear interaction) b Marginal Effects of Local Governance Quality on Revenues (Non -linear interaction)
Looking first to the theoretical implications of our study, we focus our contributions to the entrepreneurship literature on hybrid ownership, emerging market, resource dependence theory and legitimacy viewpoint. First, it systematically investigates hybrid ownership, an increasingly popular strategy employed by entrepreneurs in developing countries to improve their connections with the governments. To our knowledge, research has yet to pay sufficient attention to entrepreneurial firms with partial state ownership, irrespective that this ownership model amounts to a political connection at an institutional level (Song et al., 2016). We believe that the effects of this type of political connections on firm performance are not weaker than the effects of other well-studied political connections at the individual level because hybrid ownership is created via an explicit, written, legal contract, based upon which the government and the entrepreneurs build an institutionalised relationship (Zhang et al., 2020). As such, this study advances early work on informal (social network-based) political connections by addressing a more prominent issue associated with entrepreneurial strategic planning. Second, this study identifies a boundary in which the positive association between hybrid ownership and firm performance becomes more effective. Specifically, we show that hybrid firms are less likely to be affected by local institutional voids (such as poor governance quality). This finding helps explain the over-performance of hybrid firms against both private firms and state-owned firms. Compared to previous studies that purely focus on the impact of partial state ownership and political affiliation on access to bank loans (Du et al., 2015;Song et al., 2017), this study adds value by showing the relevance of institutional endorsement. We highlight the vital importance of partial state ownership on firm performance through an institutional viewpoint (Zhang et al., 2020).
Third, our finding suggests that hybrid ownership is not always good for entrepreneurial firms. Specifically, an unexpectedly high level of state ownership may harm firm performance. This novel finding puts a caveat on the persistent implication from the extant literature that political affiliation is always associated with benefits. We reinforce Luo et al. (2019) and Fisman et al. (2012) arguments that political relationship building can exert contradictory effects on a new venture's performance. Moreover, our results demonstrate that while state ownership is conducive to firm performance, actual involvement by the government in firm governance may be detrimental (especially to revenues and TPF). Therefore, we suggest that there is substantial heterogeneity in the types and levels of political connections. It is therefore incumbent upon entrepreneurs to evaluate the pros and cons of each strategy to make the most appropriate affiliation decision.
For organisations seeking to make the best use of the state ownership in order to enhance their performance in an emerging market like Vietnam, this study offers some key practical implications. For entrepreneurs, it may be beneficial to team up with the government for sharing business ownership. This strategy helps small firms gain access to bank loans and strategic information, and protects them from bureaucratic harassment from incomplete institutional environments. However, entrepreneurs should ensure they retain their majority power and control rights over the governance of their businesses. Thus, they can fully utilise the key strategic resources opened up to them by the hybrid form of businesses in the most appropriate and efficient manner. For policymakers, the hybrid legal form may be a better way of privatising small-sized state-owned firms than the "red hat" and rented models previously employed. Zhang et al. (2020) suggest that, as a new form of state-sector reform, mixed-ownership reform should extend beyond the privatisation of state-owned firms to operate in a reverse direction, i.e., entrepreneurs should actively seek out state ownership. As such, authorities in developing countries may consider the hybrid legal form of business ownership to be a win-win solution for both the private and state sectors in weak institutional environments.
This study is not without limitations that should be acknowledged in order to provide potential avenues for future research. First, due to data limitations, we are still unable to thoroughly separate privatised state-owned firms from hybrid firms in our sample. Even though we restrict the sample to small firms, which are much less likely to be privatised state-owned enterprises since they did not change their ownership types in the study period, there is still a possibility that the sample under investigation is not pure hybrid firms. Second, the dataset employed in this study is country-specific. One of the main weaknesses of a country-specific research design is that we only observe within-country effects, which may be influenced by social embeddedness. Future research should therefore re-test the validity of our findings using a multi-country dataset with longer survey periods. Finally, the study focuses particularly on economic performance of hybrid firms. However, other dimensions of performance such as productivity and sustainable growth are also important to evaluate the contributions of hybrid firms to the economy. Future studies should investigate these issues in more detail.
In a nut shell, entrepreneurial firms tend to exert higher political engagement and influence than established firms (Luo & Junkunc, 2008). As such, this study examines the role of hybrid ownership as a novel form of political connections employed by SMEs to gain access to key strategic resources. The context of analysis is Vietnam-a highly relevant but unexplored empirical setting in the literature of political connections. We find that hybrid legal form boosts firm performance; however, a too high level of state ownership may exert a negative impact. This study therefore has important implications that the state should have a role to play in firm ownership but should limit its role to providing resources and staying out of the governance of the hybrid firms.
