Overseas R&D and FDI Technology Spillover:An Empirical Analysis

近年来,跨国公司对华研发投资发展迅速,理论界迫切需要回答一个现实问题,即海外研发投资是否促进了我国FDI的技术外溢效应?本文运用我国28个行业的面板数据,以道格拉斯生产函数为基础计量方程,通过"外资R&D介入强度"作为分组指标展开分组检验。回归结果证实海外研发投资有助于FDI技术外溢效应的产生,在此基础上,文章给出了具体的政策建议及进一步的研究展望。

Recently, Transnational Corporations R＆D investment in China has increased in a sharp speed. One problem should be answered by Chinese Scholars is whether the overseas R＆D investment improves the FDI technology spillover effects？ This article employs Douglas Function as the basic estimation model, divides 28 industries into two groups by ＂R＆D intensity＂ , and applies regression analysis using panel data, The regression result proves that overseas R＆D contributes to the FDI spillover effect. The article also puts forward some countermeasures and future research direction based on the findings.
