Carbon emission trading has been actively applied in many countries, and its operational effect has received widespread attention. However, previous studies mostly focused on single environmental effect, and the investigation of the comprehensive environmental effect needs to be further supplemented. Based on this, this paper explores the comprehensive environmental effect of carbon emission trading with eco-efficiency as the starting point. First, this paper measures eco-efficiency using the super-efficient minimum distance to strong efficient frontier (MinDS) model with undesirable outputs. Second, this paper uses the propensity score matching difference in difference (PSM-DID) model to quantify the effect of carbon emission trading on eco-efficiency. Finally, this paper examines the mediating mechanism of the effect of carbon emission trading on eco-efficiency based on the mediating effect model. The results show that carbon emission trading can improve the level of urban eco-efficiency. Energy savings and increased efficiency effectively mediate the promoting effect of carbon emission trading on eco-efficiency. The mediating push effect of R&D innovation and industrial structure restructuring has not yet appeared. This paper can not only provide policy basis for the improvement of carbon emission trading market but also provide reference for the construction of carbon emission trading market in developing countries.
碳排放交易已在许多国家得到积极应用，其运行效果受到广泛关注。然而，以往研究大多聚焦于单一环境效应，对综合环境效应的考察有待进一步补充。基于此，本文以生态效率为切入点，探讨碳排放交易的综合环境效应。首先，本文运用含非期望产出的超效率最小距离至强有效前沿（MinDS）模型测度生态效率。其次，本文采用倾向得分匹配法的双重差分（PSM-DID）模型量化碳排放交易对生态效率的影响。最后，本文基于中介效应模型考察碳排放交易对生态效率影响的中介机制。结果表明，碳排放交易能够提高城市生态效率水平。节能与效率提升有效中介了碳排放交易对生态效率的促进作用。研发创新与产业结构调整的中介推动效应尚未显现。本文不仅可为完善碳排放交易市场提供政策依据，也可为发展中国家碳排放交易市场建设提供参考。
