Research On The Influence Of Environmental Protection Tax On Technological Innovation Of Enterprises From The Perspective Of Tax Greening

For a long time,environmental protection and enterprise techno logical innovation are two important issues that can not be ignored at any stage of development in the world.At present,there are still s ome problems in China,such as haze raging,water quality deterioration,hazardous waste discharge and so on.This year’s "Government work report" once again stressed the need to continuously promote the high quality of the manufacturing industry,the focu s is to create and enhance the level of scientific and technological innovation in China’s manufacturing industry,especially in the heavily polluting industries.On the one hand,levying environmental tax can make enterprises increase the investment in te chnological innovation,offset the tax cost with innovation results,and thus enhance the profits of enterprises;on the other hand,the collection of environmental tax will increase the sewage cost of enterprises.In the case of a certain amount of capita l investment,other funds will be "squeezed out" by the funds of technological innovation,so there may be two different roles between environmental protection tax and enterprise science and technology innovation activities.Therefore,will China’s environ mental protection tax promote the scientific and technological innovation activities of enterprises in the end? Does it have the same effect on the quantity and quality of technological innovation? What is the effectiveness of the "fee to tax" in China’s environmental protection tax?Based on the analysis of the present situation and problems of environmental protection tax and technological innovation of enterprises from the perspective of greening of tax system,this paper uses the microscopic panel data of 170 enterprises from 2011 to 2015 of 14 heavily polluting industries listed on the Shanghai and Shenzhen stock markets as the research sample.This paper establishes the panel data model,studies the effect of environmental protection tax on enterprise science and technology innovation activities under different caliber,and further uses the double difference method to simulate and estimate the effect of environmental protection tax levied in 2018 on enterprise technological innovation.The results show that the small caliber environmental protection tax can obviously improve the quantity of scientific and technological innovation in enterprises,but it is not conducive to the improvement of the quality of scientific and technological innovation.However,the environmental protection tax under medium caliber and large caliber does not have a beneficial positive effect on technological innovation.At the same time,it further considers the effect of raising the standard of sewage charge on the scientific a nd technological innovation of enterprises,so as to verify the effectiveness of the "fee to tax" in environmental protection tax in China.This confirms the positive role of China’s environmental protection tax in the technological innovation of enterpris es.Therefore,it is suggested that we should advocate the concept of green development,stimulate the vitality of technological innovation of enterprises,constantly improve the accuracy of environmental protection tax,establish a tracking and evaluation mechanism for the implementation effect of environmental protection tax,and promote the construction of "green tax" system in our country.
