财政环保支出、地方政府竞争与环境污染治理——基于中国284个城市的实证研究

Financial environmental protection expenditure,local government competition and environmental pollution control:Based on 284 prefecture-levelcities in China

基于中国2007—2019年284个地级市的面板数据,采用空间杜宾模型方法,对环保支出和地方政府竞争对环境污染治理的影响进行了实证检验。结果表明:城市间的环境污染具有空间溢出性。从整体上看,环保支出本身能够显著降低环境污染水平,地方政府竞争加剧了环境污染,环保支出在地方政府竞争的作用下对环境污染的影响不显著,但在时间和经济发展水平方面存在异质性。地方政府应合理划分财力与支出责任,加大环保支出规模,完善绿色政绩考核机制,加快产业结构升级,加速技术创新,以助力实现“美丽中国”的建设目标。

Based on the panel data of 284 prefecture-level cities in China from 2007 to 2019,this paper empirically tested the impact of environmental expenditure and local government competition on environmental pollution control by using spatial Dubin model.The results show that:Firstly,the environmental pollution between cities has spatial spillover.Secondly,on the whole,environmental expenditure itself can significantly reduce the level of environmental pollution,local government competition significantly promotes environmental pollution,and environmental expenditure has no significant impact on environmental pollution under the effect of local government competition.But there is also heterogeneity in terms of time and level of economic development.After the 18 th CPC National Congress,local governments paid more attention to environmental governance,especially in areas with better economic development.Therefore,it is necessary to rationally divide financial resources and expenditure responsibilities,increase the scale of environmental protection expenditure,improve the evaluation mechanism of green political achievements,optimize the upgrading of industrial structure,and accelerate technological innovation,so as to better realize the goal of“beautiful China”.
