Research On Technology Spillover Effects Of Chinese Students Return

With the accelerating process of globalization, the world is experiencing a big change. The flow of global resources more frequent, not only includes goods, capital, information and technology, but also about the talent. Over the years, China suffering from "brain outflow", but if China wants to realize the national rise,"global talent" as one of the international technology spillover channels is necessary. How to reverse the brain outflow situation and attract overseas talents who with international competitiveness reflux, and how effectively the returnees play the role of China’s modernization, all above that are becoming hot spot of the academic. Which also is important to promote the development of China’s studying career.This paper’s study subject is Chinese overseas students. Firstly, we base on international human capital flow theory and some related researches to summarize the factors which affecting the return of Chinese overseas students, and to investigate the mechanism of technology spillover of the returnees from four areas of human capital effects, material capital effects, competition demonstration effects and network effects. Secondly, from national policy changes and the scale of returned overseas students analyzing the current situation of China’s returnees, and further to explore the new features during the new century. Thirdly, on the basis of classical CH model constructs a model of technology spillover measuring the impact of the returnees do to the TFP of China’s30provinces and seven regional, we further comparing the difference effect of seven regional.Through the study we found:Firstly, when considering the30provinces in China as a whole, at first we can know that the technology spillover effect of overseas students return is significant, but the impact of domestic R&D investment to improve the technological progress is greater than the returnees. And the returnees by physical capital and network effects attract trade and FDI, and the trade technology spillover effect is not significant, while FDI have a positive effect. Secondly, comparing the seven regional of China we have some conclusions, except the Northeast China, the other six regions’returnees have positive effect on technological progress, and Circum-Bohai-Sea Region is most significant. The indirect effects on TFP of reflow students is more complex, and the regional heterogeneity is obvious. The input of R&D of seven areas have positive effect on improve TFP. Besides, the returned overseas students’effect on TFP in Circum-Bohai-Sea Region and Southest China is greater than physical capital investment, and this phenomenon in Circum-Bohai-Sea Region is particularly prominent. Finally, above all of these, we present some suggestions about how to attract overseas students return and how effectively to play their role of promoting technology spillover effect.
