经济增长中的FDI异质性和技术空间依赖性研究

Heterogeneity of FDI and technological spatial interdependence in the economic growth

既有经济增长中技术外溢和FDI异质性的研究,大多忽略了对空间效应的考虑。基于此,本文提出了一个包含FDI异质性和技术空间依赖性的经济增长模型——空间修正索罗模型,并运用1987-2007年中国省域的面板数据进行了固定效应的空间面板估计。研究表明:(1)省域技术水平间存在显著的空间依赖性。(2)FDI外溢效应显著地异质于国内资本。(3)邻近省域间经济发展存在较高的空间依赖性,是一个局域内相关系统。(4)全国范围内,FDI的空间外溢效应不显著;但在东部地区,FDI表现出显著的空间外溢效应。文章结论对于省域间物质资本投入、FDI引资政策制定及邻近省域经济的协同发展具有指导意义。

There are lots of literatures on the technological spillover and the heterogeneity of FDI in economic growth.However,majority literatures ignore spatial effects in the economy.Therefore a growth model of the heterogeneity of FDI together with the technological interdependence between economies-spatial augmented solow model is developed,and a fixed-effect spatial panel estimation is conducted by using the sample of Chinese provinces over the period 1987-2007.The results indicate that（1） the technological interdependence between provinces exists and remains significant;（2） FDI＇s spillover effect is significantly different from domestic physical capital;（3） the economic growth between provinces is interdependent;（4） the spatial externality of FDI is insignificant in the whole country of China,but is significant in China＇s eastern region.The conclusion is instructive in the distribution of the domestic investment between provinces,the formulation of FDI policy,and the joint development of neighboring provinces＇ economies.
