Effect Of Central Environment Protection Inspection On Ozone Pollution Control

With the continuous attention to environmental protection issues in the 13th five-year plan,China has gradually formed and improved the central environmental protection supervision system,which is considered to be a general operational governance in the field of environmental protection based on the relationship between the"principal-agent"central government and local governments.This paper makes an empirical study on the effect of environmental protection supervision policy in the summer of 2020.The results show that compared with non-supervised cities,the central environmental protection supervision action can significantly reduce the air quality index（AQI）of supervised cities by 1.788 and the concentration of fine particulate matter(PM_2.5)by 4.681μg/m³,the concentration of inhalable particulate matter(PM₁₀)decreased significantly by 6.132μg/m³,the concentration of sulfur dioxide（SO₂）decreased significantly by 1.968μg/m³,the concentration of nitrogen dioxide（NO₂）decreased significantly by1.166μg/m³,the concentration of ozone（O₃）near the ground decreased significantly by 3.308μg/m³,the concentration of carbon monoxide（CO）decreased significantly by 0.0508 mg/m³,and the impact is still significant after a series of robustness tests.This paper tests three effects based on"principal-agent"theory and campaign-style governance theory.The results show that with the increase of the degree of deterrence to local governments and officials,the punishment to illegal enterprises and individuals,and the supervision and reporting of the public and the media,the air quality of inspector cities will be significantly improved.However,for different air quality indicators,the order of the three effects is not the same.
