Evaluating the effects of China's carbon emission trading scheme (ETS) is crucial for the coordinated development of Chinese cities. Therefore, based on the panel data of 242 cities in China from 2008 to 2019, this paper uses the multi-period difference-in-difference (DID) model to comprehensively evaluate the impact of carbon market on the coordinated development of cities from the perspectives of carbon market policy and carbon market efficiency, and then analyzes the mechanism and heterogeneity of the effect of carbon market efficiency. The results show that both carbon market policy and carbon market efficiency can promote the coordinated development of cities. Science and education expenditure plays a significant intermediary role in the impact of carbon market efficiency on the coordinated development of cities. The heterogeneity test finds that the stricter the performance penalty system, the higher the level of urban coordinated development, and the stronger the effect of carbon market efficiency. The findings of this paper provide policy recommendations for further improving the construction of China's pilot and national ETS and enhancing the coordinated development of Chinese cities.
评估中国碳排放交易体系（ETS）的效果对中国城市的协调发展至关重要。因此，基于2008年至2019年中国242个城市的面板数据，本文运用多期双重差分（DID）模型，从碳市场政策和碳市场效率两个角度全面评估碳市场对城市协调发展的影响，进而分析碳市场效率影响的机制和异质性。结果表明，碳市场政策和碳市场效率均能促进城市的协调发展。科教支出在碳市场效率对城市协调发展的影响中发挥着显著的中介作用。异质性检验发现，绩效惩罚制度越严格，城市协调发展水平越高，碳市场效率的作用效果越强。本文的研究结果为进一步完善中国试点和全国碳排放交易体系建设、促进中国城市协调发展提供了政策建议。
