FDI溢出、人力资本门槛与区域创新能力——基于中国省际面板数据的实证研究

FDI Spillovers,Human Capital Threshold and Regional Innovation Capacity- Empirical Research Based on China's Provincial Panel Data

在采用永续盘存法(PIM)测算出FDI存量的基础上,利用1998—2012年中国省际平衡面板数据,在知识生产函数框架下,以人力资本为门槛变量来分析FDI对区域创新能力的溢出效应。通过把人力资本与FDI的交互项引入到模型中,证实了人力资本门槛的存在,同时通过对中国东、中、西三大区域的研究也进一步证实了人力资本门槛的存在。无论是从全国层面还是从区域层面分析,FDI并没有直接地促进创新能力的提升,只有跨越相应的人力资本门槛,FDI才能有效地促进区域创新能力的提升。

Using the panel data of 30 provinces,municipals,autonomous regions from 1998 to 2012 in China and estimating FDI stock according to Perpetual Inventory Method,the paper conducts a panel analysis of impacts of FDI stock on regional innovation capacity. The findings are as follows： After introducing the human capital threshold variable,the interaction terms of FDI and human capital promotes the innovation capacity and prove the existence of human capital threshold,and we also confirm the above conclusion through the researches on the east,middle and west regions in China. FDI does not indirectly promote the innovation capacity. Only if when surpassing the human capital threshold,FDI could promote the regional innovation capacity.
