环境规制视角下FDI对碳排放强度的影响研究

Research on the Impact of FDI on Carbon Emission Intensity from the Perspective of Environmental Regulation

本文在测算我国30个省市2003—2017年碳排放强度的基础上,运用面板门槛模型分别在全国和区域层面上实证分析了环境规制下FDI的减排效应。结果显示:①各区域间碳排放强度存在梯度差异,呈现出由东至西逐渐升高的趋势。②FDI对碳排放的抑制作用受限于环境规制水平,全国层面上二者存在双重门槛,并且随着环境规制力度的加强,FDI对碳排放的抑制作用逐渐增强,同时区域间FDI对碳排放存在不同的门槛效应。因此,各地政府应该根据自身发展水平,适度加强环境规制强度,合理选择环境规制工具,优化FDI的引资用资策略,从而加强环境规制的碳减排效应。

The paper based on the calculation of carbon emission intensity of 30 provinces and cit⁃ies in China from 2003 to 2017,using the panel threshold model,empirically analyzed the emis⁃sion reduction effect of FDI under environmental regulation at the national and regional levels.The results have showed that:①There is gradient difference in carbon emission intensity be⁃tween regions,showing a trend of gradual increase from east to west.②The inhibitory effect of FDI on carbon emissions is limited by the level of environmental regulation.At the national lev⁃el,they both exist a double threshold.With the strengthening of environmental regulation,the in⁃hibitory effect of FDI on carbon emissions is gradually enhanced,and there are different thresh⁃old effects of inter-regional FDI on carbon emissions.Therefore,local governments should ap⁃propriately strengthen the intensity of environmental regulation according to their own develop⁃ment level,reasonably choose environmental regulation tools,and optimize the strategies for FDI investment,so as to enhance the carbon emission reduction effect of environmental regulation.
