中国碳交易市场规模的减排效应研究

Research on the Emission Reduction Effect of the Scale of China’s Carbon Trading Market

文章基于2006—2017年我国30个省份的面板数据,采用连续性双重差分法评估了碳交易市场规模的碳减排效应。研究结果表明:碳交易市场规模存在碳减排效应,碳交易市场规模的扩大有利于降低试点地区碳排放量;中介效应检验发现,碳交易市场规模的扩大通过降低能源消费总量、优化能源消费结构、推动低碳技术创新以及调整产业结构等四个途径实现碳减排;由于二氧化碳与其他大气污染物之间存在同根同源性,从而碳交易市场规模在实现碳减排的同时,还能发挥协同减排效应减少二氧化硫排放量。研究结论丰富了碳交易和碳减排相关文献,对于推动绿色低碳经济转型以及推进全国碳交易市场建设提供了经验支持。

Based on the panel data of 30 provinces in China from 2006 to 2017,this paper uses the continuous DID method to evaluate the carbon emission reduction effect of carbon trading market scale.The results show that the scale of carbon trading market has the effect of carbon emission reduction,and the expansion of the scale of carbon trading market is conducive to reducing the carbon emissions of pilot areas;the mediating effect test shows that the expansion of carbon trading market can achieve carbon emission reduction by reducing the total energy consumption,optimizing the energy consumption structure,promoting low-carbon technology innovation,and adjusting the industrial structure;due to the same root homology between carbon dioxide and other air pollutants,the scale of carbon trading market can not only achieve carbon emission reduction,but also play a synergistic effect to reduce sulfur dioxide emissions.The conclusions enrich the relevant literature of carbon trading and carbon emission reduction,and provide experience support for promoting the transformation of green low-carbon economy and the construction of national carbon trading market.
