Abstract: This paper revises Dasgupta et al (1998,2002) pollutant reduction cost model,uses microdata of industrial enterprises in Liaoning Province to analyze the incentive effect of local government subsidies on environmental governance,and draws corresponding conclusions as followsFirst,based on microdata and revised pollutant reduction cost model,this paper calculates Liaoning ProvinceThe average value of environmental governance efficiency of industrial enterprises is about 83%,which is approximately normal distributionSecondly,local government subsidies have not significantly improved the efficiency of corporate environmental governance,but they have significantly improved the stability of the efficiency of corporate environmental governanceThis paper argues that the main role of local government subsidy lies in the effect of capital supplement and endorsement signal,which can improve the stability of environmental governance efficiency and reduce uncertainties on the basis of guiding a large number of excellent resources into enterprisesThird,the influence of local government subsidy on the environmental governance stability of enterprises with different types of ownership is quite different,and the stabilization effect of the efficiency improvement of domestic enterprises receiving subsidy is much lower than that of foreign enterprisesIn summary,in the absence of corresponding supervision,local government subsidies are difficult to have a significant incentive effect on environmental governance,but due to its signal guidance role,it has a significant effect on improving the stability of governance efficiency
