| Since the reform and opening up,China has gradually carried out industrialization construction,improved the strategic position of industrialization development,and escorted economic growth.However,the extensive development mode cannot ensure the stable,sustained and healthy development of the economy.Unbalanced distribution of industrial resources and overcapacity have become major problems restricting China’s economic development,especially in the metal products industry,pharmaceutical manufacturing industry,textile industry and other heavy pollution industries.Improper production capacity expansion in polluting industries will not only lead to the environment.There is a serious problem of pollution,and it will lead to the problem of insufficient use of resources.As today’s society pays more and more attention to the quality of the ecological environment,how to take into account the problem of environmental pollution in the process of maintaining rapid economic development has attracted the attention of all walks of life.The Potter hypothesis and related environmental economic theories show that environmental regulation,as a long-term incentive and restraint mechanism,can inhibit the pollution emissions of enterprises,and also promote the technological innovation activities of polluting enterprises,thus improving the utilization rate of production capacity.The Environmental Protection Tax Law of the People’s Republic of China,which was officially implemented in 2018,provides inspiration for solving the above problems: improving the environmental tax system,implementing environmental protection incentives,and encouraging enterprises to rely on innovation to achieve green development,which will improve the efficiency of resource allocation and resolve the overcapacity and production capacity of the industry.The problem of underutilization.Based on the latest data of listed companies in 2013-2021,the triple difference method is used to analyze the impact of environmental tax reform in 2018 on capacity utilization and its mechanism.The research results show that the environmental tax reform can significantly improve capacity utilization;on this basis,the results are credible through two robustness tests.In addition,through the analysis of the results of mechanism testing,environmental protection tax can affect the capacity utilization rate of enterprises in two ways: one is to promote technological innovation;the other is to curb excessive investment by enterprises.Heterogeneity analysis shows that the positive impact of environmental tax reform on enterprise capacity utilization is more significant among enterprises with poor market and financial systems.Taking the capacity utilization rate as the research perspective,this paper deeply discusses the impact of the collection of environmental protection tax on the production capacity utilization rate of enterprises,and enriches and summarizes the theory of the economic effect of environmental protection tax.Through research,we found that environmental protection tax,as a market-participating environmental regulation means,can effectively solve the problems caused by the defects of system design in the past,and effectively manage the phenomenon of enterprise overcapacity,so as to improve the utilization rate of enterprise production capacity.At the same time,we put forward the following suggestions: first,we should continue to promote the reform process of environmental tax and clarify the object,scope and standards of taxation;second,the environmental protection department and tax department should strengthen supervision to ensure that the pollution emissions of enterprises are effectively controlled and the environmental tax can be collected in full and on time;third,the government should increase the tax Support for innovative research and development to improve the incentive role of tax policies;Fourth,it is necessary to formulate differentiated environmental policies to give full play to the complementary role between environmental protection tax and the market system and financial system;Fifth,enterprises need to actively take measures to deal with environmental tax reform,actively carry out technological innovation,and improve production capacity.Use rate,so as to solve the problem of overcapacity;finally,accelerate the green transformation of enterprises and realize the high-quality and sustainable development of enterprises. |
