摘要本文将海归引入国际研发溢出的计量模型，利用中国省际面板数据模型分析海归对各地区技术进步的影响。检验结果表明海归技术溢出效应显著，但在不同地区间具有显著的差异性，并且在使用多个工具变量解决变量内生性问题后，该结论依然稳健。在此基础上，本文进一步运用Hansen（1999）提出的门槛检验方法对影响海归技术扩散效应的若干因素及其门槛特征进行检验，并从财政收入、经济发展水平等方面测算了引发海归积极技术外溢效应的门槛水平。 This paper introduces intellectual returnees to an international R＆D spiUovers model. Using China＇s provincial panel data, we study how intellectual returnees influence technological progresses in various regions of China. The analysis shows that returnees have played important roles in the technological progress in China, and the effects are differentia- ted across regions. The finding is robust after controlling the endogeneity problem with in- strument variables. We also use the threshold regression method introduced by Hansen （1999） to measure the threshold effects of several factors including local fiscal revenue, per capita GDP, R＆D spending, and human capital.
