摘　　要：以国家环保模范城市被成功命名或宣布创模为准自然实验,使用1998-2018年中国226个地级市的面板数据,采用多期双重差分方法,分析“国模”称号抑制城市环境污染的具体效果。结果表明:该政策的实施显著抑制了城市的环境污染,且模范城市的政策效果更明显,对东中部地区模范城市、西部和少数民族地区在创城市环境污染的抑制作用更强。机制分析表明,模范城市和在创城市改善环境质量的机制和路径不同,模范城市偏向于直接约束、提升技术水平和全要素生产率并行,在创城市则偏向于优先产业转型。该政策具有较强的稳定性和持续性,不会受到官员更替的冲击。Taking the national environmental protection model city successfully named or announced as the natural experiment,this paper analyzes the specific effect of the policy to curb urban environmental pollution based on the panel data of 226 cities from 1998 to 2018 by time-varying DID method.Results show that,the implementation of this policy curbed urban environmental pollution significantly,especially for model cities.The policy effect of model cities in the eastern and central region and modeling cities in the western region and ethnic minority areas are more obvious.The mechanism analysis results show that the mechanism and paths to improve the environmental quality of model cities and modeling cities are quite different.Model cities tend to adopt a parallel approach that directly restricts the improvement of technological level and total factor productivity.On the other hand,modeling cities tend to give priority to the transformation of industries.The policy has strong stability and sustainability and isn’t affected by the change of officials.
