中国OFDI逆向技术溢出的区域异质性与动态门限效应

The Regional Heterogeneity and Dynamic Threshold Effect of Reverse Technology Spillover in China's OFDI

本文利用2003～2011年我国省际面板数据，采用动态面板估计方法实证检验了我国OF—DI的逆向技术溢出效应及其吸收能力，并从人力资本、市场化指数、研发资本存量、经济规模和研发强度5个指标出发，研究了其对OFDI逆向技术溢出及其吸收能力的门限效应，并具体测算出这5个指标的门限值。研究结果表明，我国OFDI的逆向技术溢出效应显著并表现出动态特征；逆向技术溢出吸收能力较强，但表现出明显的区域异质性；在相关指标越过门限之后，两者均得到显著改善。

This paper tests the reverse technology spillover and its absorption ability of China's OFDI,using provincial-level panel data from 2003 to 2011 and dynamic panel estimation method of empirical test. Then,it studies the threshold effect of human capital,marketization index,R&D capital stock,scale of economy and R&D strength on reverse technology spillover and its absorption ability. Also,the paper calculates out threshold values. The results show that,reverse technology spillover effect of China's OFDI is significant and exhibits dynamic characteristics. Further,China has strong absorption ability that shows a marked regional heterogeneity. As the indexes exceed threshold values,both of reverse technology spillover and its absorption ability improve significantly.
