| After the modern industrial revolution,the rapid growth of industrial civilization has brought increasingly severe environmental pollution problems,and blind abuse and over-exploitation of resources abound.Improving the quality of China’s ecological environment has been placed at an unprecedented strategic height.At present,tax greening has become one of the main directions of tax reform in China.Green taxa tion and emission trading can effectively solve the environmental externalities of economic activities.By improving the greening degree of tax system,enterprises can be guided to take the initiative to undertake environmental responsibility and actively carry out environmental protection investment practice.At present,there are few empirical studies on the greening effect of tax system in academic circles,and most of them are discussed from the perspectives of green taxation and environmental regulatio n.Therefore,this paper starts from the perspective of environmental protection,and empirically studies the impact of greening degree of tax system on environmental protection investment of enterprises,which has certain theoretical contribution and practical value.To begin with,this paper firstly summarizes the literatures about tax system greening degree and enterprise environmental protection investment at home and abroad,analyzes the mechanism of tax system greening degree and enterprise environmental protection investment on the basis of pollution paradise hypothesis,factor endowment hypothesis and Porter hypothesis,and depicts the present situation and changing trend of tax system greening degree and enterprise environmental protection investment in China.Then,taking the listed companies in A-share heavy pollution industries from 2010 to 2019 as research samples,From the perspective of the greening degree of provincial tax system and the actual burden of green tax expenditure on enterprises,This paper empirically tests the influence of different tax greening degree on environmental protection investment behavior of enterprises,and further groups heavily polluting enterprises according to property rights,enterprise scale and regional characteristics,and studies whether enterprises with different characteristics and different regions will show different influences.The results show that: firstly,the environmental protection investment of heavily polluting enterprises in China is insufficient,and the scale of environmental protection investment among enterprises is quite different;secondly,there is a U-shaped relationship between the greening degree of tax system and the environmental protection investment of enterprises,That is,when the greening degree of tax system is at a low level,Enterprises have no motivation to invest in environmental protection projects that cannot generate economic benefits in time,At this time,there is a negative correlation between them,but when the greening degree of tax system is at a high level,the "a little" investment of environmental protection investment of enterprises can offset the "a large part" of the burden cost,and enterprises tend to increase the investment of environmental protection funds,at this time,there is a positive correlation between them;thirdly,compared with private enterprises and small enterprises,the "U" impact of tax greening degree on environmental protection investment of state-owned enterprises and large enterprises is mor e significant,and the "U" impact of tax greening degree on environmental protection investment of enterprises has regional heterogeneity.In the end,this paper puts forward the following policy suggestions:optimizing the tax design of environmental prot ection tax;Strengthen the green function of taxes related to environmental protection;Improve the cooperation system of green tax collection and management;Formulate supporting measures for environmental protection;Actively broaden green financing channels. |
