Abstract: Central Ecological and Environmental Protection Inspection is a major institutionally innovative measure for solving the environmental governance dilemma, and notification of negative typical cases is a key part of the measure. On the basis of clarifying the theory of deterrence effect of typical case notification, this paper uses panel data of 282 prefecture level cities from 2014 to 2020 to quantitatively evaluate the deterrence effect of typical case notification and the influencing factors. The results show that typical case notification has a deterrence effect on local governments; stern words in typical case notification strengthen the deterrence effect; directly naming the municipal Party committee and municipal government strengthens the deterrence effect; active public participation and government response magnify the deterrence effect; the deterrence effect is is significant for environmental problems that are easy to solve, but insignificant for comprehensive environmental problems that have to be solved in the long run; local governments still tend to "guarantee the bottom" in environmental governance. The above results remain robust after taking account of sample errors, replacement of measurement indicators, replacement of filed of environmental governance, etc. The findings of this study provide reliable empirical support for the effective mechanism and influencing factors of typical case notification, and provide important reference for further rational use of typical case notification.
