Research On The Incentive Mechanism Of Environmental Regulation To Enterprise Green Innovation

The pressure of resource shortage and the deterioration of the ecological environment have increasingly become barriers that hinder the high-quality development of the social economy.Therefore,governments of all countries attach great importance to the issues of resources and environment.Enterprise green innovation is an important way to save resource consumption,reduce pollution emissions and protect the ecological environment.However,due to the double externalities of environmental improvement and technology spillovers of green innovation,the rational enterprise sector lacks the power of green innovation.So it is necessary for government regulatory department to use reasonable and effective environmental regulations policies which can encourage polluting enterprises to make green innovation and achieve green and sustainable development of economy and society.This paper firstly defines related core concepts such as environmental regulation and green innovation through the literature research method,systematically combs the current status of domestic and international research on environmental regulation and green innovation,and gives the research theories such as externality theory,learning-by-doing theory,and differential game theory.Based on the relevant scholars' research,the Starkberg differential game models were established under different environmental regulation policies,by which regulators encourage polluting enterprises to practice green innovation.The model also considers the learning-by-doing effect of efficiency improvement and cost reduction of the polluting enterprises in the processes of green innovation investment and production investment.Through differential game analysis,numerical analysis and comparative analysis,respectively solves the optimal strategy equilibrium solutions of green innovation of monopoly enterprises and oligarchic enterprises,studies dynamic change trajectory of optimal equilibrium strategies and comparatively analysis the incentive effect of the green innovation and social welfare under different environmental regulation policies.The main conclusions of this paper are as follows:Firstly,learning-by-doing effect has an important impact on corporate green innovation and social welfare.After the implementation of the environmental regulation policy,the social welfare level increases with the learning rate of green innovation investment,the impact rate of knowledge accumulation on green investment costs and the impact rate of knowledge accumulation on investment efficiency.Secondly,the total investment curve of green innovation of alloligarchic enterprises in the entire cournot market always tilts upwards as the number of enterprises increases.The green innovation investment of oligopolistic enterprise decreases with the increase of the number of enterprises in the market.The curve relationship between the two shows“U” type instead of “U” type,which conforms to the Schumpeter hypothesis.Thirdly,the incentive effects of different environmental regulation policies on corporate green innovation are inconsistent.The policy incentive effects of monopoly enterprise's green innovation from high to low is “pollution tax and innovation subsidy” combination policy,“innovation subsidy” policy and “pollution tax” policy.The policy incentive effect of oligopoly green innovation from high to low is the“pollutant tax and innovation subsidy” combination policy,“pollutant tax” policy and “innovation subsidy” policy;“pollutant tax” policy,“pollutant tax and profit tax” combination policy and “profit tax” policy.Fourthly,the social welfare effects of different environmental regulation policies are inconsistent.The policy effect of social welfare level realized by green innovation of monopoly enterprises from high to low is “pollution tax and innovation subsidy” combination policy,“pollution tax” policy and “innovation subsidy” policy;the policy effect of social welfare level achieved by green innovation of oligopolistic enterprises is “pollution tax and innovation subsidy”combination policy,“pollution tax” policy and “innovation subsidy”policy.
