FDI与OFDI溢出对高技术产业区域创新的门槛效应研究

选取2003-2016年省域高技术产业面板数据，以R&D人员投入为门槛变量，实证分析FDI与OFDI溢出对高技术产业区域创新的非线性影响。得出以下稳健性结论：FDI和OFDI溢出对高技术产业区域创新具有双门槛效应，FDI溢出呈现先升后降的特征，而OFDI溢出则呈现先降后升特征；R&D人员投入、R&D资本积累、城镇化水平有利于高技术产业区域创新，而金融成熟度未产生明显推动作用；政府支持可能对R&D人力投入较高省份产生抑制作用；2003-2016年跨越R&D人员投入中、高门槛的省份在不断增加。

The Threshold Effects of Both FDI Spillover and OFDI Spillover on Regional Innovation of High-tech Industries

On an open perspective,based on the data of provincial high-tech industries in Chinese from 2003 to 2016,the threshold panel model was established taking R&D personnel input as the threshold variable,to analyze the nonlinear effects of both FDI and OFDI spillover on regional innovation of China's high-tech industries empirically.The following robust conclusions are:Both FDI spillover and OFDI spillover have double threshold effect on regional innovation of high-tech industries.The former shows the trend firstly goes up then down,while the latter firstly goes down and then rise.R&D personnel investment,R&D capital accumulation,and urbanization level are conducive to regional innovation of high-tech industries,but the financial maturity does not.Government support may inhibit innovation of provinces` high-tech industries that have high level of R&D personnel investment; From 2003 to 2016,the number of provinces that cross the threshold of medium and high R&D personnel investment is increasing.
