府际合作与公众关注度:京津冀大气污染联合治理效应研究

Intergovernmental Cooperation and Public Concern:Joint Governance Effect on Air Pollution in Beijing-Tianjin-Hebei Region

京津冀大气污染严重,治理效果甚微。在中央政府、地方政府及其职能部门的共同努力下,京津冀开启了府际环境合作治理模式。(1)公众关注度在区域联合执法改善大气污染的过程中是否发挥了作用?发挥了怎样的作用?(2)融合了府际合作治理的自上而下分析路径以及公众环境关注与参与的自下而上分析路径,京津冀联合执法行动对大气污染产生怎样的治理效应?文章基于京津冀地区空气质量日度数据同时引入公众关注度数据,运用双重差分模型论证府际合作对于公众关注度的促进作用以及分析联合执法行动的治理效应。研究发现:联合执法有助于激发公众的环境关注度进而提升联合执法的大气污染治理效应;北京及其邻近城市的执法效果优于其他地区;北京地区的执法行动对周边城市有显著溢出效应。研究结论对于完善区域环境合作治理、提升区域环境质量具有重要意义。

Air pollution in Beijing-Tianjin-Hebei region is severe and the governance effect is minimal.Under the joint efforts of the central government,local governments and their functional departments,Beijing-Tianjin-Hebei region has launched an inter-governmental cooperation model for environmental governance.(1)Did public concern play a role on the joint enforcement?Which role?(2)Combining the top-down analytical approach and the bottom-up analytical approach,what was the governance effect on the joint enforcement in Beijing-Tianjin-Hebei region?Based on the daily air quality index data in Beijing-Tianjin-Hebei region and the public concern data,this paper applies the difference-in-difference model to analysis the two questions.The study finds that joint enforcement helps stimulate public concern and thereby enhance the joint enforcement’s effect;the enforcement effect in Beijing and its neighboring cities is better than that in other areas;Beijing’s enforcement has significant spillover effects on surrounding cities.The research conclusions are of great significance for improving regional environmental cooperative governance and enhancing regional environmental quality.
