公众参与的减排效应——来自环保热线开通的证据

The Emission Reduction Effect of Public Participation--Evidence from the Launch of the Environmental Hotline

本文基于不同城市“12369”环保热线开通的时间差异,利用微观企业数据和双重差分模型考察了我国以监督、举报为主要特征的公众参与的减排效应及其内在机制。研究结果显示,环保热线开通带来了公众参与,并显著降低了企业二氧化硫排放强度,且这种减排效应具有明显的地区异质性。增加当地环境治理投资和监管力度,并促使企业强化污染末端治理是导致上述结果的重要机制。本文结论为我国加快构建现代环境治理体系,深入推进美丽中国建设提供了政策启示。

Based on time differences in the launch of the environmental hotline"12369"in different cities in China,we examine the emission reduction effects of public participation and its underlying mechanisms.We find that the launch of the"12369"brought about public participation and has significantly reduced the SOz emission intensity of firms,and this effect has significant regional heterogeneity.Increasing local governmental investment and regulatory efforts in environmental governance,and inducing enterprises to strengthen end-of-pipe treatment,are important mechanisms leading to the above results.Our findings provide policy inspiration for China to accelerate the construction of a modern environmental governance system and deepen the construction of a beautiful China.
