摘　　要：环境质量改善是城市群实现高质量协同发展的重要维度。文章采用中国十大城市群2004——2020年的面板数据,实证分析了城市群内部竞争对环境污染的影响及其内在机制。研究发现:城市群内部竞争会加剧本地污染,且同群城市之间的竞争会强化污染物空间联动性,即群内城市在“增长竞赛”中引致污染排放加剧的同时,也会导致群内其他邻近城市环境污染加重。机制分析表明,开发区设立和政府举债建设均是城市群内部竞争导致污染排放加剧的重要传导机制。进一步的异质性分析表明,2017年前,各城市群内部竞争的环境效应以污染效应为主,且发达城市群内竞争的污染效应较为明显;2017年后,各城市群内部竞争的环境效应以净化效应为主,且长三角、珠三角、京津冀以及成渝等四大城市群的净化效应最为显著。Environmental quality improvement is an important part of urban agglomeration to achieve high-quality development.Based on the panel data of China's ten major urban agglomerations from 2004 to 2020,this paper empirically analyzes the impact of internal competition in urban agglomerations on environmental pollution and the mechanism.The results show that:The competition within the urban agglomeration will lead to the increase of local pollution emissions.And the competition between the cities in the same cluster will strengthen the spatial linkage of pollutants,that is,the cities in the cluster will not only lead to the increase of pollution emissions,but also lead to the intensification of environmental pollution in other adjacent cities in the cluster.Mechanism analysis shows that the establishment of development zones and the government debt,which are the important transmission mechanisms of pollution emissions caused by local government competition.Further heterogeneity analysis shows that before 2017,the environmental effects of competition within urban agglomerations were mainly pollution effects,and the pollution effects of competition within developed urban agglomerations were more obvious.After 2017,the environmental effects of competition within urban agglomerations are mainly purification effects,and the purification effects are the most significant in the Yangtze River Delta,the Pearl River Delta,Beijing-Tianjin-Hebei and Chengdu-Chongqing urban agglomerations.
