摘要
随着"引进来"和"走出去"战略更好地结合,扩大对外直接投资已经成为我国经济发展的必然。本文利用我国29个省市2004～2009年的数据,运用Eviews和DEAP软件,对我国29个省市的全要素生产率进行了度量,并对我国对外直接投资与我国全要素生产率之间的关系进行了实证分析。研究结果表明,我国对外直接投资对我国全要素生产率的提升有正向的促进作用,我国对外直接投资存量每增加1%,国内全要素生产率将增长0.006%,虽然作用强度不大,而且它对全要素生产率增长的作用要低于国内研发支出,但从长期来看,对外直接投资能促进我国技术进步。这说明中国应当继续加大我国国内研发投入的力度,并且通过增加投资力度等方式提高对外直接投资对于技术进步的贡献度。
With the combination of ＂Bringing in＂ and ＂Going out＂ , expanding OFDI has become an inevitable trend of our economic development. This paper uses panel data of 29 provinces from 2004 to 2009, measuring our 29 provinces＇ total factor productivity, and make an empirical analysis between OFDI and total factor productivity. The results demonstrate that OFDI performs a positive role in enhancing the total factor productivity. As the stock of OFDI increases 1%, the total factor productivity will enhance 0.006%. Although the effect is not significant and its contribution rate to the growth of total factor productivity is lower than the expense of R＆D, OFDI can improve the technology in long term. So we should continue to increase the expense of R＆D, and to enhance the degree of contribution of OFDI to the total factor productivity by means of increasing OFDI.
