Under the "dual-carbon" strategic goals, it is urgent to examine whether the energy consumption permit trading scheme （ECPTS）, as an innovative system in China's market-oriented reform of the energy sector, can promote the synergistic enhancement of pollution reduction and carbon abatement. Based on provincial panel data of China from 2008 to 2019, this study adopted a difference-in-differences model to examine the impacts of the ECPTS on the synergistic enhancement of pollution reduction and carbon abatement. The results demonstrated that the ECPTS improved the level of pollution reduction and carbon abatement in pilot areas. Specifically, the ECPTS led to a reduction of 13.3% in CO emissions and 3.1% in PM concentration in the pilot areas and resulted in an overall improvement of pollution reduction and carbon abatement by 0.237 units. Mechanism analysis revealed that energy efficiency served as a pathway through which the ECPTS empowered the synergistic enhancement of pollution reduction and carbon abatement. Moreover, the strengthening of local government environmental protection goals enhanced the pollution reduction and carbon abatement effects of the ECPTS. Surprisingly, the effectiveness of the ECPTS was not undermined by the goal of economic growth. This study provides new empirical evidence for understanding the relationship between market-based environmental regulation and collaborative governance and provides strong support for China to achieve its "dual-carbon" strategic goals.
在“双碳”战略目标下，审视作为中国能源领域市场化改革创新制度的能耗许可交易计划（ECPTS）能否促进污染减排与碳减排协同增强，已成为当务之急。基于2008年至2019年中国省级面板数据，本研究采用双重差分模型考察了ECPTS对污染减排与碳减排协同增强的影响。结果表明，ECPTS提高了试点地区的污染减排和碳减排水平。具体而言，ECPTS使试点地区的一氧化碳排放量减少了13.3%，颗粒物浓度降低了3.1%，污染减排和碳减排总体提升了0.237个单位。机制分析表明，能源效率是ECPTS推动污染减排与碳减排协同增强的一条途径。此外，地方政府环境保护目标的强化增强了ECPTS的污染减排和碳减排效果。令人惊讶的是，经济增长目标并未削弱ECPTS的有效性。本研究为理解基于市场的环境规制与协同治理之间的关系提供了新的实证证据，并为中国实现“双碳”战略目标提供了有力支持。
