Heterogeneity Analysis of Environmental Regulation Affecting Enterprise Green Innovation
This paper puts environmental regulation and enterprise green innovation into a unified analysis framework,investigates the mechanism of environmental regulation's influence on enterprise green innovation,and focuses on the heterogeneity of green patent type,enterprise ownership and industry attribute.The results show that the environmental regulation has a U-shaped nonlinear influence on enterprise green innovation.When the intensity of environmental regu-lation exceeds a certain critical value,the influence of environmental regulation on enterprise green innovation will change from inhibition effect to promotion effect.Compared with green utility model patents,environmental regulation has a more prominent influence on green invention patents.Environmental regulation has a monotonous growth promoting effect on non-manufacturing enterprise green innovation,while its influence on manufacturing enterprise green innovation is U-shaped.Moreover,the influence of environmental regulation on green innovation of different ownership enterprises is U-shaped,but the critical value faced by non-state-owned enterprises is obviously smaller.Consequently,this paper puts forward that the formulation of environmental regulation strategies should not be"one size fits all",but should actively design differentiated environmental regulation strategies.
