摘要：China's environmental regulation policy has been effectively developed from 2007-2019. Under the effect of environmental regulation, enterprises begin to pay attention to the technology innovation and the effective reduction of carbon emissions. In order to explore the mediating effect of green inno-vation on the relationship between environmental regulation and carbon emissions,and the moderating effect of enterprise cost control on the relationship between environmental regulation and green innova-tion, this paper takes the panel data of 30 provinces in China for nearly ten years as samples,analyzes the mediating and moderating effect model, and con-ducts robustness test and reliability test for the data model. The research shows that positive environ-mental regulation not only has an incentive effect on enterprise operation directly, but also indirectly im-proves energy utilization efficiency and reduces car-bon emissions through green product innovation and green process innovation. The incentive effect of market environment regulation on green product in-novation can be strengthened by increasing invest-ment in technological innovation. There is no signif-icant moderating effect on the relationship between market environmental regulation and green process innovation. Based on the empirical test, this paper finds that on the basis of the current policy intensity, we should moderately strengthen the mandatory en-vironmental regulation, gradually increase the scope and intensity of environmental tax collection, imple-ment differentiated environmental protection tax rate, and give full play to the synergistic effect of environ-mental regulation and enterprise science and tech-nology investment.
