The Relationship Between Environmental Regulation,R&D Subsidy And Green Innovation

Under the background of the increasingly prominent contradiction between economic development and ecological environment,at the Fifth Plenary session of the 18 CPC Central Committee,China raised the green development to the height of the national development strategy,and pointed out clearly on 19 th CPC National Congress the direction and route of green development in the future.It is an important way to alleviate the pressure of resource restriction and environmental pollution,and has laid the foundation stone of green development of our country.However,inpractice,the current level of green innovation is not high,and the reality of uneven development hinders the pace of green development.From the point of view of theory research,the existing literature has not systematically studied the path of green innovation.Based on this,this study starts from the perspective of "dual externalities" and spatial spillover of green innovation.The spatial Doberbin model of environmental regulation,R&D subsidy and green innovation is constructed by using panel data of provincial areas in China from 2007 to 2015,and the realization mechanism of green innovation is deeply analyzed.From the perspective of complementary policy advantages,this paper further studies the regulatory role of R&D subsidies in the relationship between environmental regulation and green innovation,in order to provide valuable guidance for China’s green development.The main conclusions of this study are as follows.First,green innovation in China has obvious spatial agglomeration and spatial autocorrelation.The areas with high level of green innovation are mainly concentrated in the eastern coastal areas,where the economy is relatively developed.It shows the characteristic of decreasing from east to west.Green innovation has significant spatial autocorrelation and significant spatial spillover effect.Second,the influence of environmental regulation on green innovation is heterogeneity.Command environmental regulation,public participation environmental regulation significantly positively promote green product innovationand green process innovation,while incentive environmental regulation negatively affects green product innovation.However,the impact on green process innovation is not significant.Third,R&D subsidy has a significant role in promoting green innovation,but the spillover effect on green innovation is different.The spillover effect of R&D subsidy on green product innovation is not significant,but it will have significant negative spillover effect on green process innovation.Fourth,there is a complementary advantage between R&D subsidy policy and environmental regulation policy,and R&D subsidies have promoted the positive impact of environmental regulation on green innovation.
