Abstract
This paper investigates the effect of foreign bank entry on the export quality of firms. For this purpose, we mainly use the transaction data from the Chinese Customs Database and the production data from the Annual Survey of Industrial Firms of China during the years 2000–2006. The obtained data consists of 62,483 observations gathered from 19,888 firms. The results show that foreign bank entry enhanced the export quality of firms that are more externally financially dependent. This influence is stronger for non-state-owned firms and ordinary-trade firms than for the other types of firms. We further demonstrate that foreign bank entry is mainly through promoting innovation endeavors and improving the quality of intermediate inputs yielding to enhance the export quality of firms that have more external financial requirements.

Notes
Similar to Kose et al. (2010), the openness of the banking sector here means legal restrictions on foreign banks are deregulated.
Another significant reform in the financial market was the most recent deregulation of the restrictions on foreign banks in 2018. However, the COVID-19 pandemic slowed down the development of foreign banks as well as international trade, making a sample period after 2018 less suitable for examining the relationship between foreign bank entry and firm export quality.
For example, the endogenous problem may arise from the omitted variable biases. Foreign bank entry and the export quality of firms could be affected by the same regional and/or firm characteristics. In addition, there could be a simultaneity bias. The quality upgrading of the exports of firms would promote the upgrading of industrial structures in a region, while the upgraded industrial structures and the improved business environment could attract more foreign banks.
By the end of 2001, the restrictions were alleviated for Shenzhen, Shanghai, Dalian, and Tianjin; subsequently, at the end of 2002, Zhuhai, Guangzhou, Nanjing, Qingdao, and Wuhan were opened. Further openings occurred at the end of 2003 for Fuzhou, Jinan, Chongqing, and Chengdu. At the end of 2004, Beijing, Kunming, and Xiamen were opened and, finally, at the end of 2005, Ningbo, Shantou, Xi’an, and Shenyang were also accessible.
For example, if the banking sector’s openness to foreign banks enables firms to alleviate their financial constraints, these firms could lower their production costs and subsequently reduce their export prices. As a result, firms would increase their export volume without changing their exportation quality.
A bank is considered as foreign-owned if it is originated from a country or region outside of mainland China.
Between the end of 2001 to the end of 2003, the geographic restrictions on foreign banks for conducting RMB business were gradually removed in several cities, but foreign banks were still only permitted to carry out RMB business with foreign individuals and firms. Between the end of 2003 to the end of 2005, both the geographic and the client restrictions on foreign bank lending were gradually removed in several cities. Since the end of 2006, these bans were lifted in all cities. In this paper, we only consider the liberalization of geographic restrictions on foreign banks in China.
The sigma data were obtained from http://www.columbia.edu/~dew35/TradeElasticities/TradeElasticities.html. We also used the product-invariant elasticities of substitution in the robustness check (refer to A.1 in Appendix A). In addition, the mean (7.5) and median (2.8) of elasticities of substitution, provided by Broda and Weinstein (2006), were also used to respectively estimate the export quality. All the results indicate that our conclusion remained the same for different choices of elasticity of substitution.
We match different classifications on economic statistics based on their correlation table from https://unstats.un.org/unsd/classifications/Econ.
Since the end of 2003, the client restrictions have been lifted for all opened cities.
The main reason for using the sample period of 2000–2006 is that all the geographic restrictions on foreign bank lending in China were removed after the end of 2006. In addition, most of the existing works, based on CCD, also used the sample period of 2000–2006 (Liu and Qiu 2016; Zhang and Ouyang 2018).
To avoid measurement errors, we deleted firms with annual sales revenue below RMB 5 million and those that have less than eight employees or negative and zero total assets.
Our sample includes the following regions: Shenzhen, Shanghai, Xi’an, Dalian, Shenyang, Tianjin, Ningbo, Qingdao, Guangzhou, Shantou, Zhuhai, Xiamen, Beijing, Nanjing, Kunming, Wuhan, Chongqing, Jinan, Chengdu, Fuzhou, Guiyang, Lanzhou, Zhengzhou, Hangzhou, Nanning, Hefei, Shijiazhuang, Haerbin, Taiyuan, Yinchuan, Huhehaote, Changsha, Wulumuqi, Nanchang, Xining, Haikou, Lasa, and Changchun.
After controlling for the firm’s characteristics and a series of fixed effects, only 57,344 observations were included in the regressions.
In China, ordinary- and processing-trade exports account for more than 90% of the total exports (Tang et al. 2021). We only retained the ordinary- and processing-trade exports in our sample.
The R&D investment data were obtained from the ASIF database for the sample period of 2005–2007. He et al. (2018) provided the patent data for the sample period of 2000–2006.
For example, according to Eq. (4), if we want to estimate the quality of a product originating from an African country, we should use the disaggregate transaction data of that country.
As mentioned in the Appendix (A.1), the share of high-tech imported intermediate inputs can serve as a proxy for the quality of imported intermediate inputs (Lall 2000; Zhang and Ouyang 2018). The existing studies also point out that the unit price can well capture quality (e.g., Kugler and Verhoogen 2012; Feenstra and Romalis 2014; Fan et al. 2015; Fieler et al. 2018). For example, Bas and Strauss-Kahn (2015) used the unit price of imported intermediate inputs to reflect quality.
Because Shanghai and Shenzhen were opened to foreign banks before the end of 2001, we also deleted these two cities to conduct a robustness check. The result remained consistent with our main finding.

Appendices
Appendix A
1.1 Robustness check
1.1.1 Alternative measure of key variables
An alternative measure of export quality. In our baseline model, the elasticities of substitution vary among varieties (Broda and Weinstein 2006). In this study, a constant elasticity of substitution was deployed to estimate the export quality. In Column (1) of Table
7, \(\sigma { = 4}\) was used to re-estimate the export equality, as defined by Khandelwal et al. (2013). The result reinforces our baseline result.
In Sect. 3.1, we mentioned that most firms export several products classified in HS 6-digit codes; therefore, we used the weighted average of export quality to calculate the export quality of a firm (refer to Eq. (5)). To conduct a robustness check, we considered the quality of a firm’s main product (i.e., the largest export product) as its export quality. We report the result in Column (2) of Table 7; it reveals that there still exist a significantly positive coefficient associated with the interaction term although its magnitude decreases.
We also adopted the percentage of high-technology exports relative to the total exports as the measure of export quality for each firm. As mentioned by Lall (2000), if a firm shifts its export structure from low-technology to high-technology products, the export quality of this firm is improved. We applied Lall (2000) and Zhang and Ouyang (2018) methods to calculate the proportion of exports with high technology for each firm. The result is reported in Column (3) of Table 7. Once again, the result was found to be consistent with our baseline result.
An alternative measure of EFD. In our baseline result, we used the weighted average of the EFD for the sectors covered by a firm to calculate the EFD of that firm. To conduct a robustness check, we applied the sector of the main product of a firm (i.e., the largest export product) in the initial year as the essential sector of the firm, and we adopted the EFD of that sector to denote its dependence on external financing. As presented in Column (4) of Table 7, the coefficient associated with FB × EFD remained significant and positive; thus, the measurement of a firm’s EFD did not drive our findings.
So far, we have used the U.S.-based EFD measure to conduct our estimations. As a robustness check, we replaced the U.S.-based measure with that calculated using the Chinese data. Referring to Kroszner et al. (2007) and Manova et al. (2015), the EFD of the firms is defined as the ratio of their liabilities to assets. In China, the external financing of firms is mainly obtained from bank loans; thus, the liabilities of firms can basically reflect their external funds derived from banks (Ye et al. 2019). To eliminate the concern of endogeneity, we used the liability ratio for each firm in the initial year to denote the level of a firm’s EFD. The related result is reported in Column (5) of Table 7, and it reveals that foreign bank entry have significantly enhanced the export quality of firms with greater EFD.
1.2 More controls
City-level controls. In the baseline results, our identification strategy can alleviate the omitted variable problem. However, one may still wonder whether the export quality of firms is affected by other funding sources that are connected to the funding received from foreign banks. To address this concern, we introduce a series of additional city-level controls to capture the effects of other sources of financing on the firms’ export quality. The city-level controls include the Gross Domestic Product (GDP) per capita, the number of domestic banking branches, the scale of the Foreign Direct Investment (FDI), and the government budget expenditure. The results are reported in Column (1) in Table
8. These findings prove that our main results still hold even when considering the other financing sources of firms.
Firm-level controls. In addition, we introduce other firm-level features, which may also impact the firms’ export quality to our baseline results, including firm age and the basic technical ability measured by intangible assets. The results, reported in Column (2) of Table 8, show that they are consistent with our baseline results.
1.3 Lagged explanatory variables
One may consider that firms may require time to adjust their export quality; hence, time-lagged independent variables should be used in the estimations. In this work, we alleviate this concern by using our identification strategy (refer to Sect. 4.2), which captures the average treatment effects after allowing foreign bank entry. However, to make our estimation more robust, we re-regressed the export quality of firms on the one-year-lagged explanatory variables displayed in Column (3) of Table 8 where we lagged behind all of the explanatory variables by one year. Once again, our main result remained robust.
1.4 Alternative samples
A sample including all cities. In the baseline, we included China’s main cities (38 cities) to reduce the difference between the treatment and control groups to the maximum possible extent. In this subsection, we used a sample that includes all cities (223 cities) to re-estimate our baseline where Column (4) in Table 8 presents the result. The magnitude of the coefficient of FB × EFD was close to the values in Column (6) of Table 8. Therefore, the findings prove that our method is robust.
A sample includes only “opened cities.” As mentioned in Sect. 4.3, our sample included the “opened cities” selected by the government as well as cities that were not opened to foreign banks until the end of 2006 but were very similar to the “opened cities”. However, the “opened cities” and “non-opened cities” may still have differences in some aspects even if there were no policy shocks. To make the treatment and control groups more similar before foreign bank entry, we used a sample that included only the “opened cities” before the end of 2006. Thus, the coefficient of FB × EFD presented in Column (5) of Table 8 remained positive and significant. Therefore, our baseline results are robust.Footnote 21

Appendix C
The estimated export quality (Fig. 1 and Table 10).
Appendix D
Firm-level exchange rate.
A firm’s real effective exchange rate is computed following Brodsky (1982):
where c is the firm f’s export destination in one year, C denotes the number of export destinations in one year, \(E_{ct}\) represents the nominal exchange rate of RMB with regard to the currency for country c in year t, \(E_{c}\) indicates the nominal exchange rate in the initial year, \(CPI_{t}\) denotes China’s Consumer Price Index (CPI) in year t, \(CPI_{ct}\) represents the country c’s CPI in that year, and \(\frac{{y_{c} }}{y}\) is the firm f’s share of export to country c initially, which is used as a weight. Therefore, \(REER_{ft}\) is the real effective exchange rate weighted by firms’ export. If a firm faces RMB appreciation currently, the \(REER_{ft}\) value will increase.
Appendix E
Foreign bank entry and export quality over time (Table 11 and Figs. 2 and 3).
Appendix F
Foreign bank entry and firms’ access to bank loans.
Since the external financing of Chinese firms is mainly from bank loans, firms’ liabilities can essentially indicate their external funds derived from banks (Ye et al. 2019). Therefore, the results proposed in Table
12 suggest that foreign bank entry increases both the long-term bank loans and total bank loans of domestic firms.
