外商直接投资如何影响省域创新效率——兼论环境规制的空间调节效应

How does FDI Affect Regional Innovation Efficiency?

摘要:

从中国省域面临着FDI引入、环境保护、创新要素空间流动特征及创新驱动发展的经济转型问题,以2004-2015年中国30个省域的面板数据为样本,采用超越对数生产函数,并利用随机前沿模型测度了各省域的创新效率。从基于引力模型的省际创新要素流动视角构建空间关联流动权重,利用空间杜宾模型考察了FDI对区域创新效率的空间异质性影响,并讨论了FDI和环境规制的空间交互效应,研究表明：(1)在R D人员流动权重 和R D资本流动权重 下,本省域及其周围省域的FDI对该省域创新效率均产生了显著的空间异质性挤出效应,尤其在R D资本流动权重 下此挤出效应更为明显；(2)本省域及其周围省域的环境规制对该省域创新效率均产生了明显的杠杆效应,尤其在 下此杠杆效应更为显著；(3)加入FDI和环境规制的交互项后,本省域及其周围省域环境规制与创新效率呈现倒U型动态变化关系。

Abstract:

The Chinese province region facing FDI,environmental protection, the characteristics of spatial innovation elements flow and the development of economic transformation driven by innovation. This paper,selecting provincial panel data between 2004 and 2015 in China as the sample,uses the translog production function and stochastic frontier model to measure the provincial innovation efficiency. Based on gravity model,the spatial association flow weights are constructed from the perspective of dynamic factors of innovation between provinces. The spatial Durbin model is used to investigate the differential influence of FDI on regional innovation efficiency. Research shows that: (1) R D in personnel flow weight and R D in capital flow one,FDI in the province and its surrounding provinces has dynamic heterogeneity significant squeezing effect on the regional innovation efficiency, more obvious especially in the R D capital flow weight;(2)The environmental regulation in the province and its surrounding provinces has a significant leverage effect on the innovation efficiency of the province,more obvious especially in the R D capital flow one;(3)adding the interaction of FDI and the environmental regulation,the province and its surrounding provinces of environmental regulation and innovation efficiency has inverted U-type dynamic relationship.
