Brain drain, as a form of migration, refers to talented young people moving from poor developing countries to advanced countries in the pursuit of education at universities, research, or work in areas where education and employment opportunities are limited in their home countries. Developing countries and regions, such as India, Taiwan, and mainland China worry about their brain drain and the consequential economic loss, as their human capital was the last resource they wanted to lose in a national competition (Saxenian, 2005; Todaro, 1985). Migration of skilled talent from developing countries to advanced countries during the late twentieth century has mainly involved migration from India and China to the USA. For instance, in 1998 to 1999, 10.4% of international students enrolled in American universities were from mainland China (51,000 not including Hong Kong), and 7.6% were from India (37,482) (Todd, 2000). Furthermore, between 1990 and 1996, 16,749 Chinese students and 8211 Indian students received their doctoral degrees in Science and Engineering from American universities (Johnson, 1998). With Silicon Valley’s rapid growth in the technology sector from the 1970s through the 1990s, skilled technical immigrants from developing countries who came to the USA for Science and Engineering education found jobs in Silicon Valley. By 2000, 53% of Silicon Valley’s scientists and engineers were foreign born, with Indian and Chinese nationals accounting for over one quarter of the total personnel (estimate 20,000 Indians, 5000 Taiwan, and 1500 mainland China born) (Saxenian, 2005).
In contrast to brain drain, brain circulation happens when skilled overseas population return to their home countries after years of learning, living, and working abroad. Some are called transnational entrepreneurs who return to home countries to start businesses through their established overseas business links. Transnational entrepreneurs spread international knowledge about the global markets while, at the same time, link economic opportunities between their home countries and host countries (Liu, 2017; Saxenian, 2005). Other returnees go back to teach at universities, while many work for multinational companies (Beaverstock, 2002; Cyranoski, 2002; Varshney, 2013; Zweig et al., 2004). Brain circulation, or brain gain, usually generates positive outcomes for their home countries because of the skills, capital, knowledge, or business connections the returnees bring back with them (Stark et al., 1998).
Literature on return migration has been discussed primarily on four theoretical models: the economic model, the structural approach, the transnational model, and the triangular model. The economic model emphasizes factors such as salary, living conditions, and family obligation (Guo & DeVoretz, 2006; Todaro, 1969; Zweig & Chen, 1995). Early generation Chinese doctoral degree recipients in Science and Engineering in the USA are an example of the economic framework (Zeithammer and Kellogg, 2013). Between 1988 and 1996, of 16,500 Chinese citizens who received doctoral degrees in Science and Engineering, 85% planned to stay in the USA. Of those who planned to stay, half of them had firm offers, one-third had real jobs, and two-thirds held postdoctoral fellowships (Zweig et al., 2004). China’s economic conditions at that time discouraged students from returning home. Due to economic gaps with the West, the material benefits for overseas returnees were incomparable to what they could obtain abroad (Chang & Deng, 1992).
The structural approach attributed return migration to social and institutional factors in the country of origin (Li & Lo, 2012). Research on China’s brain drain focused on political hurdles proposition (Chang, 1992; Zweig & Chen, 1995; Zweig et al., 2008; Simon & Cao, 2009). Overseas Chinese students were reluctant to return to China especially after the 1989 Tiananmen incident, despite China’s political leader, Deng Xiaoping’s reassurances that despite those students’ political attitude, all of them can return to China with no further punishment. Last, the transnational model (Andersson and Konrad, 2001; Ley & Kobayashi, 2005) and the triangular model rationalized the move of immigrants with a focus on skilled talents, who are often temporary movers with a strategic plan (De Voretz et al., 2003; Guo & DeVoretz, 2006; Zweig et al., 2008).
Factors that influence overseas talent’s decision to return include political stability and sustained economic growth in home countries, change of political views and cultural values, homesickness and attachment to roots, racism and integration issues in host countries, tightening immigrant policies, and children’s education (Zweig et al., 2004, 2008; Fu, 2014; Varshney, 2013). In the case of China’s brain drain and brain gain, Chang and Deng (1992) revealed that Western influence has changed the social values of some overseas Chinese students. They embraced the value of individualism, and no longer put the state or national interests above their own pursuit of happiness and freedom. In the case of India, during the dotcom bubble period, some Indians who worked in information technology industry were forced to go back due to the economic slump and massive unemployment in the USA (Chacko, 2007). A recent study has shown that many Indians choose to return in recent years, as Indian higher education quality is increasing, providing more opportunities for returning talent’s children in their home country. The internationally recognized Indian Institutes of Technology (IITs) and the Indian Institutes of Management (IIMs) offer a satisfying educational prospect to the children of those who wish to return to India.Footnote 6
Brain circulation to China is not new, in particular to those people who wanted to seize the business opportunities and large Chinese markets to make their fortunes. Policymakers and representatives in China visited Silicon Valley repeatedly to recruit Chinese technical professionals to go back home. Most representatives came from Beijing and Shanghai. As Saxenian (1999) noted, Chinese cities such as Beijing established returning students venture parks exclusively designed for enterprises established or run by overseas returnees. The municipal governments offered infrastructure and financial benefits to address their needs, such as housing, tax benefits, and children’s education. Beijing’s Zhongguancun in Haidian district was known as a famous “returning students venture park.” For instance, the founder of Baidu.com returned to Beijing and established Baidu.com in 2000 while his family stayed in Silicon Valley. Interestingly, by 2000, when representatives from Beijing flew to Silicon Valley to lure back talent to create “China’s Silicon Valley,” Shenzhen was transitioning from a labor-intensive export economy to “electronics-focused, and innovation-oriented” developmental direction led by the Shenzhen city government. As a new city in rapid catch-up mode, Shenzhen’s talent policy is nothing new in terms of China’s national initiative in attracting overseas returnees. However, it is different from Beijing or Shanghai’s efforts in the early 1990s. Today, Shenzhen’s robust Internet industries and other technological companies enable it to attract significant overseas talent.
Besides brain circulation who are transnational entrepreneurs, overseas Chinese scientific diaspora has been attracted to return to China in recent years. By the end of 2015, over 79.9% of Chinese overseas students who completed their tertiary or post-graduate studies had returned to China. Among those returnees, many of them are doctoral degree holders who carry the mission to advance China’s national scientific research and to turn China’s leading universities into world-class level institutions (MOE, 2016; Zweig & Wang, 2013).
This article is constructed in three major sections. The first following section analyzes Shenzhen’s talent policy, Peacock Talent program, and the role central and city government play in attracting human capital as well as how domestic and foreign talents who were attracted to Shenzhen view the talent policy. The second part analyzes current brain circulation to China due to the international geopolitical chaos and its impact. The final section summarizes Shenzhen’s current talent situation and offers concluding remark on policy implication which can be drawn from Shenzhen.
