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.
