To achieve the goal of energy conservation and emission reduction, China has launched its national carbon-emission trading scheme (ETS). Therefore, it is of great significance to evaluate the implementation of ETS from the perspective of regional ecologicalization efficiency of industry. Based on the panel data of 30 provinces and cities from 2007 to 2019, this study takes the SBM-DEA model to measure the regional ecologicalization efficiency of industry, uses the Difference-in-Difference (DID) model to evaluate the influence of ETS on the regional ecologicalization efficiency of industry, and verifies the outcome by propensity score matching method and counterfactual test. The mediating effect model is used to test the acting pattern of ETS on the regional ecologicalization efficiency of industry. The results show that: (1) ETS can significantly improve the ecologicalization efficiency of industry and shows regional heterogeneity. (2) ETS promotes regional energy conservation, emission reduction, and economic development because of the upgrading of structural optimization, agglomeration of resource synergy, and optimization of ecology. This study offers penetrating insights into the positive operation of the carbon market and provides some useful hints for the development of China's regional economy.
为实现节能减排目标，中国推出了全国碳排放交易体系（ETS）。因此，从产业区域生态化效率的角度评估 ETS 的实施具有重要意义。本研究基于 2007 年至 2019 年的 30 个省、市的面板数据，采用 SBM-DEA 模型测算了产业区域生态化效率，利用 DID 模型评估了 ETS 对产业区域生态化效率的影响，并通过倾向得分匹配法和反事实检验进行了验证。采用中介效应模型检验了 ETS 对产业区域生态化效率的作用模式。结果表明：（1）ETS 可以显著提高产业的生态化效率，且表现出区域异质性；（2）ETS 通过结构优化升级、资源协同集聚以及生态优化，促进了区域的节能减排和经济发展。本研究深入剖析了碳市场的积极运行，为中国区域经济的发展提供了有益启示。
