Research On The Impact Of Environmental Protection Fee-to-tax Reform On Technological Innovation Of Heavily Polluting Enterprise

With the proposal of the new development concept,people pay attention to the optimization of the living environment while pursuing economic growth and living standards.The emergence of pollution charges has improved environmental problems,and the introduction of environmental protection tax has further standardized the emission behavior of enterprises.Environmental protection tax has experienced a stage from scratch and become a research hotspot in recent years.At the same time,as an important driving force of high-quality development,innovation plays an important role in promoting China’s economic growth and enhancing the country’s overall strength.In the context of sustainable development and the construction of a strong country with innovation,enterprises,as the main carrier of innovation activities,play a role in innovating technology and promoting the green transformation of the industry.It has higher environmental costs under the regulation of environmental tax.Therefore,it is still necessary to further consider whether the implementation of environmental protection tax fee change can effectively promote the technological innovation level of heavy polluting enterprises,so as to achieve the goal of emission reduction still needs further consideration.On this basis,based on the data of enterprises in the heavily polluting industries listed in Shanghai and Shenzhen during 2012-2021,this paper uses the differential model to test the impact of environmental protection fee and tax change on the technological innovation of the heavily polluting enterprises,and measures the innovation process of the heavily polluting enterprises from the two aspects of innovation input and innovation output.The results show that the implementation of environmental protection fee tax has significantly promoted the innovation input and innovation output of Chinese heavy polluting enterprises.Further considering the degree of market competition,it is found that the environmental protection fee tax policy can promote the technological innovation of heavy polluting enterprises by improving the degree of market competition.In addition,the study also found that the environmental protection tax for the promotion of heavy pollution enterprise technology innovation in the region,marketization degree and the enterprise property rights presents heterogeneity,and central region with high degree of marketization of the promoting effect is more apparent,the non-state enterprise’s innovation and the innovation of state-owned enterprises input-output promoting effect more apparent.The research conclusion expands the content of related fields and has reference significance for the optimization of environmental protection tax and the construction of green tax system.
