Research On The Impact Of Environmental Protection Tax On Green Innovation Of Enterprises

Under the extensive economic development model,China’s environmental situation has gradually deteriorated.After satisfying their material needs,people began to seek a better living environment and pursuit a better,high-quality life.Chinese government began to implement the environmental protection tax system in 2018,finished the conversion of pollution discharge fees to environmental protection taxes.The green technology innovation of enterprises can effectively change the production technology of enterprises,reduce the damage of enterprises to the environment,improve environmental conditions,promote economic development and change of economic development mode,and the collection of environmental protection tax has a significant impact on enterprise innovation.We recognize that solving environmental problems can start with the impact of environmental protection taxes on green technology innovation in enterprises.On the one hand,the collection of environmental protection tax will inhibit enterprise green technology innovation in terms of enterprise cost,enterprise production willingness,enterprise capital,etc.On the other hand,the collection of environmental protection tax can improve the production efficiency of enterprises,offset cost inputs,and occupy the market faster to promote the innovation of green technology of enterprises.Therefore,the impact of environmental protection tax on enterprises’ green technology innovation needs to be viewed dialectically.The Yellow River Basin is of great ecological significance.In September 2019,a symposium on ecological protection and high-quality development of the Yellow River Basin was held in Zhengzhou,Henan.Ecological protection and high-quality development of the Yellow River Basin have become a major national strategy.And in October 2021,the CPC Central Committee and the State Council officially issued the Outline of the Yellow River Basin Ecological Protection and High-quality Development Plan,and at the symposium on in-depth promotion of ecological protection and highquality development of the Yellow River Basin held in Shandong,General Secretary Xi Jinping stressed that the "14th Five-Year Plan" is a key period to promote ecological protection and high-quality development of the Yellow River Basin.What impact will environmental protection taxes have on the green technology innovation of enterprises in the Yellow River Basin?The paper is based on the theory of externalities,the theory of Pigou taxation,Cost theory and the Porter hypothesis.After sorting out the relevant achievements at home and abroad,collected patent and financial data of A-share listed companies in nine provinces and regions of the Yellow River Basin(Gansu,Qinghai,Sichuan,Ningxia,Inner Mongolia,Shaanxi,Shanxi,Henan and Shandong)from 2016 to 2021.Taking the official effective effect of the environmental protection tax in 2018 as the time of policy impact,which is the first difference the implementation standard of environmental protection tax is used as the second difference,finally the industry pollution degree of enterprises is taken as the third difference,the impact of environmental protection tax on green technology innovation of enterprises is analyzed.It further discusses the performance of state-owned enterprises and non-state-owned enterprises,and whether the size of enterprises will affect green technology innovation.The main conclusions that were reached are: The implementation of environmental protection tax will have a restraining effect on the green technology innovation of listed enterprises in the Yellow River Basin.Compared with the number of green utility model patent applications,the inhibition effect on green invention patents with higher technical content is greater.In the heterogeneity of enterprise property rights,the environmental protection tax will have a stronger inhibitory effect on state-owned enterprises and a weaker inhibition effect on non-stateowned enterprises.In the heterogeneity of enterprise scale,the green technology innovation of large-scale enterprises was significantly inhibited,and the inhibition of small-scale enterprises was less significant.Finally,it puts forward policy suggestions to better promote the innovation of green technology of enterprises,including increasing the scope and tax rate of environmental protection tax,improving preferential reduction policies and tax system arrangements,and increasing media publicity.The research conclusion of this paper not only relies on scientific research methods to reveal the role of environmental protection tax on enterprise green technology innovation in the Yellow River Basin,enriches the research results in related fields,but also provides a certain reference for the promotion and improvement of environmental protection tax and stimulates enterprise green technology innovation.
