| A series of environmental problems exist behind our vigorous economic development.Therefore,green sustainable development has become an important strategy of our development.In order to better balance economic development and environmental protection,green innovation is a necessary and effective way of green sustainable development.Enterprise pollution emission is a major source of pollution in our country.Therefore,the national level actively advocates enterprise green innovation,but there is also a need for enterprises to actively respond to national policy,so discussing the impact of green innovation from the enterprise level can better promote the development of green innovation.Enterprises need to be willing to take the initiative to fulfill their environmental responsibility to carry out green innovation.Capital investment in environmental protection is the pollution prevention and control investment at the front of the pollution emission link of enterprises,and it is an important reflection of enterprises’ voluntary responsibility for environmental protection.Then how will capital investment in environmental protection affect enterprises’ green innovation? In addition,internal control can not only supervise all links of enterprise environmental protection activities,but also prevent risks in the process.Therefore,the quality of internal control is related to the enterprise’s attention to environmental protection issues,so what role does internal control play between capital investment in environmental protection and green innovation?First of all,this paper summarizes the literature on capital environmental input,green innovation and internal control,and makes a theoretical analysis on the relationship between capital environmental input and green innovation,as well as the selection of internal control as the regulating variable of capital environmental input and green innovation.Secondly,this paper selects listed companies from 2008 to 2020 as samples to build a multiple regression model.Through the empirical analysis,the following conclusions are drawn:(1)Capital environmental investment can promote the green innovation behavior of enterprises.(2)Internal control has a positive moderating effect between capital investment in environmental protection and green innovation.(3)Compared with heavy polluting industries,in non-heavy polluting industries,capital environmental input has a more significant role in promoting green innovation and regulating internal control.(4)Compared with low environmental regulation level,under high environmental regulation level,capital environmental input has a more significant promoting effect on green innovation and regulating effect on internal control.Based on the above research results,this paper puts forward corresponding suggestions:(1)enterprises should actively fulfill the social responsibility of environmental protection and improve the quality of their own internal control.(2)The government should set reasonable environmental regulations to guide enterprises’ green innovation and implement differentiated environmental regulations in different industries.(3)Improve people’s awareness of environmental protection,and give play to the public’s supervision function on enterprise environmental protection issues.Therefore,this research can promote the high-quality development of enterprises,promote the industrial upgrading transformation in economic development,and provide certain theoretical basis for enterprises to carry out green innovation. |
