京津冀生态协同政策对环境规制效率的影响研究

Impact of Beijing-Tianjin-Hebei Ecological Coordination Policy on Environmental Regulation Efficiency

生态环境已经成为京津冀协同发展的关键因素。为探究京津冀生态协同政策对环境规制效率的影响效应,文章基于2009—2020年中国省域面板数据,以京津冀地区整体为研究对象,运用超效率SBM模型和合成控制法,评估京津冀生态协同政策实施对其环境规制效率的影响效应,并进行有效性检验。研究发现,京津冀环境规制效率总体呈波动上升趋势,波动幅度较小,仍有提升空间;生态协同政策实施对区域整体的环境规制效率具有一定促进作用,但其增长速度相较于别的地区是缓慢的,这表明京津冀生态协同治理机制仍需进一步完善。对此,应充分考虑区域异质性,加强顶层设计,从深化生态环境联建联防联治、推动减污降碳协同增效等方面,逐步提高京津冀环境规制水平和生态协同治理能力。

Ecological environment has become the key factor to realize the coordinated development of Beijing-Tianjin-Hebei region.In order to explore the impact of Beijing-Tianjin-Hebei ecological synergy policy on the efficiency of environmental regulation,based on China’s provincial panel data from 2009 to 2020,the paper took the Beijing-Tianjin-Hebei region as a whole as the research object,by using the super-efficiency SBM model and the synthetic control method,the effects of the implementation of the Beijing-Tianjin-Hebei eco-coordinated policy on the efficiency of environmental regulation were evaluated,and the effectiveness was tested.The results showed that the environmental regulation efficiency of Beijing-Tianjin-Hebei region showed an upward trend with a small fluctuation range,and there was still room for improvement.The implementation of the ecological coordination policy can promote the environmental regulation efficiency of the region as a whole,however,its growth rate is slow compared with other regions,indicating that the mechanism of ecological coordination between Beijing,Tianjin and Hebei needs to be further improved,and regional heterogeneity should be fully taken into account,we will gradually improve environmental regulation and ecological coordination in the Beijing-Tianjin-Hebei region,from the aspects of deepening the joint construction,prevention and control of the ecological environment,strengthening top-level design,and promoting the synergy of pollution and carbon reduction.
