摘　　要：利用1999—2021年我国283个地级市的面板数据,采用双重差分法实证分析文明城市评选政策的环境效应。研究发现,文明城市评选政策的实施显著降低了工业二氧化硫排放强度和工业废水排放量。文明城市评选政策通过源头防治与末端治理提升城市减排治污水平。其中,末端治理主要表现为提高污染治理水平和环境设施投资水平,源头防治主要表现为技术创新效应、产业结构效应和人力资本效应。此外,文明城市评选政策的环境效应因城市人口规模、海陆位置、区域分布、行政等级和历史底蕴的不同而产生差异。基于研究结论提出政策建议,以期深化文明城市评选的政策效果,拓宽提升城市减排治污效率的路径。The Civilized City Evaluation policy plays a critical role in pollution control and energy conservation in China,significantly contributing to promoting green and low-carbon urban development.This study uses panel data from 283 prefecture-level cities in China from 1999 to 2021 and applies the difference-in-differences(DID)method to empirically analyze the environmental effects of the Civilized City Evaluation policy.The findings reveal that the policy significantly reduces industrial sulfur dioxide emission intensity and industrial wastewater discharge,enhancing urban pollution reduction and treatment levels through two main pathways:source prevention and end-of-pipe treatment.End-of-pipe treatment primarily operates through increased investment in pollution control and environmental infrastructure,while source prevention is achieved via three mechanisms:technological innovation effects,industrial structure effects,and human capital effects.Moreover,the policy's effectiveness varies depending on city population size,coastal location,regional distribution,administrative status,and historical context.
