外商直接投资的经济增长效应及区域异质性特征

The economic growth effect of FDI and regional heterogeneity

以2000-2016年我国260个地级及以上城市为研究对象,采用动态面板模型和差分GMM方法,实证检验外商直接投资(FDI)的经济增长效应及区域异质性特征。结果表明:FDI与城市经济增长之间呈现显著的倒"U"型非线性关系,但具有区域异质性特征。FDI与东部、中部以及西部城市经济增长之间均呈现显著的倒"U"型非线性关系,而FDI与东北地区城市经济增长之间并不存在非线性关系,甚至没有直接关系。FDI与城市全要素生产率增长之间呈现显著的倒"U"型非线性关系,但具有区域异质性特征。FDI与东部城市全要素生产率增长之间呈现显著的倒"U"型非线性关系,而与中部、西部以及东北地区城市全要素生产率增长之间并未呈现出明显的非线性关系。

This paper takes 260 prefecture-level cities and above in China from 2000 to 2016 as the research object,and uses dynamic panel model and differential GMM to test whether the economic growth effect of foreign direct investment(FDI)has inverted U-shaped feature and whether it has regional heterogeneity.The results show that there is a significant inverted U-shaped nonlinear relationship between FDI and China’s urban economic growth,but it has obvious regional heterogeneity.In the urban samples of the eastern,central and western regions,the relationship between FDI and urban economic growth show a nonlinear relationship of inverted U-shaped,while there is no direct relationship between FDI and urban economic growth in urban samples in Northeast China.Furthermore,there is a significant inverted U-shaped nonlinear relationship between FDI and China’s urban total factor productivity growth,and it has significant regional heterogeneity.There is a significant nonlinear relationship of inverted U-shaped between FDI and urban total factor productivity growth in urban samples in the eastern regions,and the nonlinear relationship of inverted U-shaped does not exist in the urban samples in the central,western,and northeastern regions.
