摘　　要：污染防治是发展中国家面临的重要问题,寻找和评估行之有效的环保政策是环境经济学的研究重点。本文通过双重差分方法识别了自2016年开启的第一轮中央环保督察对中国的污染防治的全面影响以及作用机制。研究发现,第一轮中央环保督察使得被督察城市的AQI、PM_(2.5)、PM_(10)、SO_(2)显著改善,但CO、NO_(2)和O_(3)没有显著变化。中央环保督察通过自下而上的公众关注和自上而下的环保执法两条机制发挥作用。Pollution prevention and control is an important issue facing developing countries.Finding and evaluating effective environmental protection policies is the focus of environmental economics.This paper uses the difference-in-difference method to identify the overall impact and mechanism of the first round of the Central Environmental Protection Inspections(CEPI)in China.We find that the first round of CEPI led to significant improvements in AQI,PM_(2.5),PM_(10) and SO_(3)in the inspected cities,but there were no significant changes in CO,NO_(2)and O_(3),CEPI functions through two mechanisms:bottom-up public attention and top-down environmental law enforcement.
