异质环境规制对OFDI逆向绿色创新的动态调节效应研究

Research on the Dynamic Regulation Effect of Heterogeneous Environmental Regulations on OFDI’s Reverse Green Innovation

基于命令型、自愿型和经济型环境规制的三维视角,运用中国省际面板数据及门槛计量技术,实证探讨OFDI对国内绿色创新的异质动态影响。研究表明:OFDI逆向绿色创新存在显著的异质环境规制门槛效应,表现为在命令型环境规制调节下呈现U形演化规律,在自愿型和经济型环境规制约束下均具有N形动态特征;只有实施较高强度的命令型和自愿型环境规制以及保持适度的经济型环境规制,才会最有利于释放OFDI逆向绿色创新溢出,且这一动态演化特征存在显著的空间差异。现阶段3种环境规制工具均在驱动OFDI逆向绿色创新过程中发挥了积极的调节效果,且表现出两大鲜明特征:从工具差异看,命令型环境规制作用最佳,经济型环境规制次之、自愿型环境规制最差;从地区差异看,中部地区最为明显,西部地区次之,东部地区最弱。

Based on the three-dimensional perspective of mandatory,voluntary and economic environmental regulations,this study uses China’s inter-provincial panel data and threshold measurement technology to empirically discuss the heterogeneous dynamic impact of OFDI on domestic green innovation.The results show that OFDI’s reverse green innovation has a significant heterogeneous environmental regulation threshold effect,which is manifested as a U-shaped evolution rule under the regulation of command-type environmental regulation,and it has N-type dynamic characteristics under the constraints of voluntary and economic environmental regulation.Only the implementation of higher-intensity mandatory and voluntary environmental regulations and maintaining moderate economic environmental regulations,will it be most conducive to the release of OFDI’s reverse green innovation spillovers,and this dynamic evolution feature has significant spatial differences.At the present stage,all three environmental regulatory tools have played a positive regulatory effect in driving the OFDI’s reverse green innovation process,and have shown two distinct characteristics.From the perspective of tool differences,the mandatory environmental regulation is the best,the economic environmental regulation is the second,and the voluntary environmental regulation is the worst.From the perspective of regional differences most obvious in the central region,followed by the western region,and the weakest in the eastern region.
