摘要
基于2005—2016年我国省际面板数据,首先通过OLS、DIFF-GMM、SYS-GMM3种基准线性回归方法论证了OFDI逆向技术溢出对我国区域创新能力的促进作用。以OFDI为核心解释变量,分别构建以地区腐败、市场化程度和知识产权保护为门槛变量的动态门槛回归模型。结果发现:随着地区腐败程度加深,我国区域创新能力逐渐减弱;以市场化程度、知识产权保护为门槛变量,跨越门槛点后OFDI对我国区域创新能力的拉动作用依次增强。最后,结合面板向量自回归模型进一步研究对外直接投资过程中地区腐败、市场化程度和知识产权保护对区域创新能力的动态即期冲击。结果显示:市场化程度单位变动对区域创新能力的影响呈现正向冲击且持续性较强,知识产权保护对区域创新能力的拉动最为迅速但后期持续性较弱,地区腐败对区域创新能力产生负向冲击作用。
Based on the inter-provincial panel data of China from 2005 to 2016, this paper firstly demonstrates the promotion of OFDI Reverse Technology Spillovers on regional innovation capability in China through three benchmark linear regression methods, namely OLS, DIFF-GMM and SYS-GMM.Then, OFDI is used as the core explanatory variable to construct dynamic threshold regression models with regional corruption, marketization and intellectual property protection as the threshold variables.The results show that: with the deepening of regional corruption, China's regional innovation capability gradually weakened; with the degree of marketization, intellectual property protection as the threshold variables, the OFDI's pulling effect on China's regional innovation capability has been strengthened in turn after crossing the threshold.Finally, combined with the panel vector autoregressive model(PVAR model), we further study the impact of regional corruption, marketization and intellectual property protection on regional innovation capability in the process of OFDI.The results show that the impact of unit change of marketization degree on regional innovation capability is positive and persistent.Intellectual property protection is the fastest but weaker in the later period.Regional corruption has a negative impact on regional innovation capability.
