基于异质性环境规制视角下FDI对碳排放的影响研究

Research on the Impact of FDI on Carbon Emissions from the Perspective of Heterogeneous Environmental Regulation

本文利用2000-2015年我国30个省区面板数据,运用面板模型和门槛模型估计方法,考察异质性环境规制下FDI对碳排放的影响研究,得出如下结论:第一,在不考虑环境规制情况下,FDI与碳排放总量呈现正相关;第二,在命令控制型环境规制下,FDI整体不利于中国的碳排放事业,且在较高的环境规制水平下,环境规制的约束力已经完全失去作用,FDI对碳排放的促进作用呈现恶性增加;第三,在市场激励型环境规制下,FDI与碳排放之间呈现一种“U”型关系,随着环境规制的强度不断上升,FDI对碳排放由抑制作用转变为促进作用,本质上是市场激励型环境规制约束作用失效;第四,在公众自愿型环境规制下,FDI整体增加了中国碳排放总量,且随着公众自愿型环境规制的强度增加,FDI对碳排放的促进作用加强。

This article uses panel data from 30 provinces and regions in China from 2000 to 2015,and uses panel models and threshold model estimation methods to examine the impact of FDI on carbon emissions under heterogeneous environmental regulations.The following conclusions are drawn:Firstly,without considering environmental regulations,FDI is positively correlated with total carbon emissions.Secondly,under command and control environmental regulations,FDI as a whole is not conducive to China's carbon emissions cause,and at a higher level of environmental regulation,the binding force of environmental regulations has completely lost its effectiveness,and the promoting effect of FDI on carbon emissions has shown a malignant increase.Thirdly,under market incentive environmental regulations,there is a"U-shaped"relationship between FDI and carbon emissions.As the intensity of environmental regulations continues to increase,FDI's role in carbon emissions changes from inhibitory to promoting,essentially rendering the constraint effect of market incentive environmental regulations ineffective.Fourthly,under public voluntary environmental regulations,FDI has increased China's overall carbon emissions,and as the intensity of public voluntary environmental regulations increases,the promoting effect of FDI on carbon emissions strengthens.
