| From June 2013 to April 2014,seven pilot carbon emission trading markets were launched gradually as the priors.Based on that fact,the study tries to verify the effectiveness of pilot carbon emission right trading markets in China from the aspect of industrial green efficiency and answer the question of what is the mechanism?Firstly,the study analyzes the theoretical relationship between carbon emission trading markets and industrial green efficiency by analyzing the cost and the benefit of industrial enterprises covered by carbon emission trading markets,draws the conclusion theoretically that carbon emission trading markets could improve regional industrial green efficiency.Secondly,the study calculates the global Malmquist-luenberger index and its decomposition using DEA model based on the SBM directional distance function and data of 30 provinces from 2007 to 2016 in China to measure the industrial green total factor productivity,industrial green technical efficiency and industrial green technology progress to be the indicator of regional industrial green efficiency.Based on the quasi-natural experiment of carbon emission trading in seven pilot areas,PSM-DID method was adopted to study whether carbon emission trading could promote the industrial green efficiency.Lastly,the study tests whether carbon emission trading improves regional industrial green efficiency through environmental protection innovation effect and energy substitution effect using mediation effect model.The main conclusions of the study are as follows :(1)Pilot carbon emission trading markets have a significant positive impact on industrial green TFP and industrial green technology efficiency but no significant impact on the industrial green technology progress.(2)Pilot carbon emission trading markets improve the industrial green TFP through environmental innovation effect and energy substitution effect.(3)Pilot carbon emission trading markets improve industrial green technology efficiency through environmental innovation effect and energy substitution effect. |
