外向直接投资对国内技术促进的实证分析

摘要

为探究外向直接投资与国内技术进步二者之间的相关关系，选取我国1991至2010年间的相关时间序列数据作为样本进行尝试性回归检验，结果表明，我国外向直接投资规模对国内技术存在促进作用，并且这种促进作用主要源于溢出的国外研发资本，但同时也得出，国外研发资本对技术的促进作用远低于国内研发资本，这也意味着我国外向直接投资对国内技术促进存在着很大的潜在贡献空间。%In order to make out that the correlativity between OFDI and technique improvement , the paper preceded a re-gression analysis by using time series data from year 1991 to 2010 .The result is that the acceleration on technology im-provement from OFDI does exist, and mainly comes from foreign R&D capital stock that spills from OFDI .However, compared with the effect acting by domestic R&D capital stock on TFP , the effect of foreign R&D capital stock is really weak, at the same time, it also means the nation’s OFDI will have potential large contribution space to the improvement of the technology .
