实现碳达峰碳中和是一场广泛而深刻的经济社会系统性变革，离不开固根本、稳预期、利长远的法治保障作用。论文基于2007—2022年284个城市的面板数据，实证分析了环境公益诉讼试点政策对城市碳排放“量降质增”的影响。研究发现，中国环境公益诉讼试点政策能够有效促进城市碳排放“量降质增”。异质性分析表明，环境公益诉讼试点政策的实施能够显著降低南方城市碳排放的“量”，提升北方城市碳排放的“质”，该政策在行政级别高的城市对提升碳排放“质”能够发挥更优的作用。机制分析表明，试点政策能够通过提升城市绿色创新能力和政府环境关注度促进城市碳排放“量降质增”，环保处罚力度在试点政策降低城市碳排放“量”和提升“质”的过程中发挥正向调节作用，负面媒体关注度在试点政策降低城市碳排放“量”的过程中发挥负向调节作用，而正面媒体关注度在试点政策提升城市碳排放“质”的过程中发挥正向调节作用。论文研究结果为中国从司法规制角度约束城市碳排放、促进城市经济高质量发展提供了理论支撑和政策启示。

Achieving carbon peaking and carbon neutrality constitutes an extensive and profound systemic economic-social transformation,which cannot be accomplished without the fundamental,expectatio-stabilizing and long-term enabling role of the rule-of-law guarantee.Based on panel data from 284 cities from 2007 to 2022,this paper empirically analyzes the impact of the pilot policy of environmental public interest litigation on the “quantitative reduction and qualitative increase” of urban carbon emissions.The study finds that China's pilot policy on environmental public interest litigation can effectively promote the “quantitative reduction and qualitative increase” of urban carbon emissions.Heterogeneity analysis shows that the implementation of the pilot policy of environmental public interest litigation can significantly reduce the quantity of carbon emissions in southern cities and improve the quality of carbon emissions in northern cities,and the policy can play a better role in improving the quality of carbon emissions in cities with high administrative levels.The mechanism analysis shows that the pilot policy can promote the “quantity reduction and qualitative increase” of urban carbon emissions by improving the city's green innovation ability and the government's environmental concern,the environmental protection penalty plays a positive moderating role in the process of improving the quantity and quality of urban carbon emissions in the pilot policy,the negative media attention plays a negative moderating role in the process of reducing the quantity of urban carbon emissions in the pilot policy,and the positive media attention plays a positive moderating role in the process of improving the quality of urban carbon emissions in the pilot policy.The research results provide theoretical support and policy implications for China to regulate urban carbon emissions from the perspective of institutional regulation and to promote high-quality urban economic development.
