Researchon Theinfluence Of Environmental Protection Tax On Enterprise Technology Innovation

Since the reform and opening up,China’s economy has developed rapidly with the acceleration of industrialization,but the problems of environmental damage and resource waste have become increasingly serious.Practice has proved that the traditional extensive economic development model can not be sustained.Polluting enterprises gathered a batch of high input,high emissions and consumable enterprises,while in terms of stimulating the economy development of our country give play to the important role of the engine,but it is undeniable is the root of resources and environmental problems in China,innovation drive heavy pollution enterprise green transition is the only way to build a resource-saving and environment-friendly society.The past research of scholars both at home and abroad focused on environmental regulation and environmental control,the relationship between the economic development,China formally in 2018 after the implementation of the environmental protection tax law of the People’s Republic of China,more and more people begin to pay close attention to the innovation effect of green taxes,green taxes associated with dynamic of technological innovation exist in many problems worth studying,For example,the effect mechanism of environmental protection tax on enterprise technological innovation,whether environmental protection tax can promote enterprise technological innovation,and whether it will produce different results for enterprises with different nature,scale and cash flow.Through the research on the above issues,it is of great significance to put forward reasonable suggestions for improving the environmental tax system from the perspective of guiding enterprises’ innovative behavior.On the basis of summarizing the relevant theories and literature of environmental tax and technological innovation,this paper divides the effects of environmental tax on technological innovation into three types: promotion,inhibition and threshold or "U" type effects,and explains the mechanism of environmental tax on technological innovation from the substitution effect,compensation effect and crowding effect.Use A shares listed on the 16 panel data of heavy pollution industry,through the establishment of fixed effects model,green taxes under different diameter was studied in the role of enterprise technology innovation activities,results show that the diameter and large diameter significantly encourage enterprise technology innovation,green taxes and under the small green taxes does not produce positive effect on technology innovation,In addition,environmental protection tax has a heterogeneous impact on enterprise technological innovation: small-caliber environmental protection tax inhibits the technological innovation of non-state-owned holding enterprises,small-scale enterprises and enterprises with insufficient cash flow,while medium-caliber environmental protection tax has a greater incentive effect on technological innovation of non-state-owned holding enterprises,small-scale enterprises and enterprises with insufficient cash flow.From the perspective of encouraging enterprises’ technological innovation and improving the environmental protection tax system,some policy suggestions are put forward,such as improving the design of tax rate,perfecting the tax system and changing the mode of collection and management.
