Chinese Graduate Students and U.S. Scientific Productivity
研究了中国博士生赴美留学对科学生产力的影响，发现中国学生在博士期间的科研产出显著高于其他学生，甚至接近美国国家科学基金会博士奖学金获得者水平。
The migration of young Chinese scientists to undertake graduate studies in U.S. universities is arguably one of the most important recent episodes of skilled migration. Using a new data set covering around 16, 000 Ph.D. graduates in 161 U.S. chemistry departments, we show that Chinese students have a scientific output during their thesis that is significantly higher than other students. In fact, conditional on acceptance into the same programs, Chinese students perform about as well as the awardees of the NSF doctoral fellowship program. These results shed new light on the benefits of student migration on scientific productivity of destination countries. © 2013 The President and Fellows of Harvard College and the Massachusetts Institute of Technology.
