摘要:

新能源示范城市试点是促进中国深入推进生态文明建设的一项重要举措,客观评估其对环境污染的治理效果,对于这一试点政策的进一步推广具有重要意义。本文基于中国261个地级市2002—2016年的面板数据,应用倾向得分匹配法和双重差分法评估了新能源示范城市建设对环境污染的治理效应,并在此基础上引入偏差校正的非参数百分位Bootstrap法,对效应的内在机制进行了解析。研究结论表明:第一,新能源示范城市建设会显著减少废水和废气的排放,进而有效降低城市环境污染;第二,新能源示范城市可以通过能源技术创新效应、产业结构优化效应和财政资金扶持效应3条中介路径实现对环境污染的治理;第三,新能源示范城市建设过程中产生的污染治理效应存在异质性,主要体现为:一方面,经济增长水平较低的城市在进行示范城市建设的过程中往往会产生更大的污染治理效应;另一方面,示范城市的人力资本水平越高,其越能有效地抑制污染物的排放。本研究为中国进一步推进新能源示范城市建设战略、提高新能源示范城市建设质量、总结与推广新能源城市建设经验以及深入研发与推广新能源技术提供了依据。

Abstract:

The pilot construction of new energy demonstration cities is an important policy for deepening the development of the Chinese ecological civilization. Objectively assessing its effect on environmental pollution is of great significance for further promotion of the pilot projects. Based on the panel data of 261 prefecture-level cities in China from 2002 to 2016, this study evaluated the effect of new energy demonstration city construction on environmental pollution by applying the propensity score matching method and the double difference method, and introduced the nonparametric deviation correction based on this. The nonparametric percentile Bootstrap method analyzes the intrinsic mechanism of effects. The conclusions of the study indicate that: First, the construction of new energy demonstration cities will significantly reduce the discharge of wastewater and waste gas, thereby effectively reducing urban environmental pollution. Second, the new energy demonstration cities can achieve environmental pollution control through energy innovation effect, industrial structure optimization effect, and financial support effect. Third, the pollution control effect generated during the construction of new energy demonstration cities is heterogeneous, mainly reflected in that on the one hand, new energy demonstration cities with lower economic growth levels are more effective in controlling pollution; on the other hand, the higher the human capital level of the new energy demonstration cities, the more effective it can suppress pollutant emissions. These conclusions provide an important basis for China to further promote the construction strategy of new energy demonstration cities, improve the quality of new energy demonstration cities, disseminate the experiences of constructing new energy cities, and deepen research and development and promotion of new energy technologies.
