排污权交易试点的波特效应研究——基于中国11个试点省市的数据

Study on the Potter Effect in Pilot Projects of Emissions Trading:Based on the Data of Eleven Pilot Provinces and Cities in China

在我国经济转向高质量发展阶段,如何更好地促进经济发展与生态环境的良性互动是亟需重点关注的问题。基于市场机制的排污权交易制度在我国已经试点十余年,排污权交易是否实现了"波特假说"提出的环境和经济双赢呢?使用全国省级面板数据,将2007年的11个试点省市设为实验组,通过构造两个DID模型分别对排污权交易的经济效应和减排效应进行实证研究。研究结果发现排污权交易在我国试点地区实现了"波特效应",但效果较弱;分区实证表明西部地区的"波特效应"强于东部地区。

In the stage of China＇ s economy developing into high - quality, how to promote the positive interaction between economic development and ecological environment is a matter of great concern. The emissions trading system based on market mechanism has been piloted in China for more than ten years. Has the emissions trading realized the win - win situation of environment and economy proposed by ＂porter hypothesis＂ 7 In this paper, based on the provincial panel data, 11 provinces and cities in 2007 are set up as experimental groups, and two DID models are constructed to empirically study the economic and emission reduction effects of emissions trading. The results of the study indicate that in the pilot areas of China, the emissions trading really have ＂Potter Effect＂, however, the effect is weak; and the ＂porter effect＂ in the western region is stronger than that in the eastern region.
