摘要
新能源示范城市建设是推动可再生能源优先发展和构建生态文明体系的重要战略举措。文章基于2005—2018年我国240个城市面板数据,采用双重差分法和中介模型实证分析了新能源示范城市建设对城市环境污染的影响效应及机制。结果发现:新能源示范城市建设对城市污染物排放具有显著抑制作用,在经过稳健性检验和内生性处理后,研究结果依然有效;新能源示范城市的环境治理效应存在异质性,对中东部地区的污染减排效果较为明显,且对大城市和可再生资源城市的污染抑制作用更加显著;新能源示范城市主要通过政府支持、社会投资、技术创新和产业升级等渠道对城市污染产生影响,且政府支持和社会投资的中介传导作用更强。
The construction of new energy demonstration cities is an important strategic measure to promote the priority development of renewable energy and build an ecological civilization system.Based on the panel data of 240 cities in China from 2005 to 2018,this paper empirically analyzes the impact effect and mechanism of new energy demonstration city construction on urban environmental pollution by using DID method and intermediary model.The results show that the construction of new energy demonstration city has a significant inhibitory effect on urban pollutant emission,and the research results are still valid after robustness test and endogenous treatment;the environmental governance effect of new energy demonstration cities is heterogeneous,which has an obvious effect on pollution reduction in the Middle and East,and has a more significant inhibitory effect on the pollution of big cities and renewable resource cities;new energy demonstration cities mainly affect urban pollution through government support,social investment,technological innovation,and industrial upgrading,and the intermediary role of government support and social investment is stronger.
