An Empirical Study On The Impact Of Environmental Regulation On The Enterprises' R&D

In recent years,more and more domestic cities' PM2.5 index hit “unhealthy”levels,and the problem of environmental pollution has become urgent.The environment is a resource with strong public property,which is likely to be a “free rider” phenomenon.At the same time,environmental pollution has a strong negative externality.If the government does not take administrative intervention on the market,it will eventually lead to “the tragedy of the Commons”.Our government has issued several relevant regulation policy to deal with environmental pollution,but how to coordinate the relationship between ecological environment and economic sustainable and healthy development still worth further study.Traditional economists thought that environmental regulation would have added enterprise operation cost,crowded out technology innovation resources,restrain enterprise technology innovation,reduced the enterprise market competitiveness.But Potter had challenged the viewpoint,he thought the strict and reasonably designed regulation policy brought R&D with "squeezing out effect",but at the same time brought about "innovation effect",which stimulating the enterprise technology innovation.From the long-term and dynamic perspective,the strict environmental protection policy made the enterprise to realize its own resource utilization was low,and the increasing environmental cost forced companies to improve the existing process and technical level.Based on environmental regulation theory,innovation theory and the porter hypothesis,this article analyses the current situation of environmental pollution,environmental regulation and enterprise R&D in our country.In this paper,I use panel data model selecting industrial industry during the years 2010-2015 of environmental data and industry data.Build the nonlinear model between environmental regulation and enterprises' R&D.A regression model is built to study the impact of environmental regulation on enterprise' R&D input.Based on the different types of region,property and the level of industry pollutionship,study the change of relationship between environmental regulation and enterprises' R&D.The research results show that the relationship between the intensity of environmental regulation and the investment of R&D is the "U" trend.Due to the difference of the external factors of eastern,central and western region of natural endowment,geographical environment,the level of human capital and economic development level,the relationship between enviromental regulation and enterprises' R&D input is not the same in every region.The relationship shows a trend of "U" type and significant in the eastern region,but the relationships between the intensity of environmental regulation and enterprises' R&D input are not significant in the central and western region;According to the nature of property right,the whole sample is divided into two subsample of state-owned enterprises and non-state-owned enterprises,studies show that the relationship between intensity and R&D input shows a trend of "U" type and significant in non-state-owned enterprises group,but environmental regulation effect is not significant in state-owned enterprises group;According to the pollution degree of the industry,the whole sample is divided into heavy pollution industry and non-heavy pollution industry,research shows that environmental regulation intensity and R&D input shows a trend of "U" type and significant in the group of non-heavy pollution industry,but environmental regulation effect is not significant in the group of heavy pollution industry...
