Carbon Emission Reduction And Pricing Decision Of P Enterprise’s Supply Chain Considering Carbon Tax And Subsidy Model

As the national "carbon peak" and "carbon neutral" goals are proposed,more and more enterprises begin to incorporate dual carbon goals into their development strategies.Meanwhile,more and more carbon emission reduction policies begin to get on track,and sustainable development and green supply chain begin to run through the development goals of enterprises.At present,the proliferation of express packaging has undoubtedly caused large-scale pollution and waste.In order to reduce the carbon emissions caused by express packaging materials,green packaging products are born.,Enterprises will invest a lot of time and funds in research and development to reduce carbon emissions,which will inevitably increase the financial burden of enterprises.The government provides a series of carbon emission reduction policies to improve the enthusiasm of enterprises to reduce carbon emissions,including government subsidies and carbon taxes.P enterprise has been committed to the emission reduction research and development of green packaging products,and government subsidy policies can help P enterprise solve the problem of capital load caused by carbon emission reduction,so as to improve the enthusiasm of P enterprise for carbon emission reduction.There are mainly two types of government subsidy policies for carbon emission reduction.One is based on the development cost of emission reduction,and the other is based on the emission reduction level of unit product.Different subsidy policies are bound to produce different subsidy effects.Therefore,based on the two subsidy policies,this paper builds the supply chain model of green packaging products under the two subsidy policies,and provides comparative analysis and suggestions for P enterprise’s emission reduction and pricing decision of green packaging products under different subsidy policies.In order to control a large area of carbon emissions,the government usually adopts a carbon tax policy with high practical applicability.Considering the future carbon emission reduction problems that P enterprise may encounter,this paper takes into account the influence of carbon tax on the emission reduction decision-making of P enterprise on the basis of different subsidy policies,aiming at providing more comprehensive emission reduction decision-making suggestions for P enterprise.This paper constructs a green supply chain Stackelberg game model composed of P enterprise and retailers.The government is willing to provide subsidies and may implement carbon tax policies to promote lower carbon emission reduction of P enterprise.P enterprise is mainly responsible for the production and R&D of green packaging products,making decisions on the wholesale price of products and the emission reduction level of unit products.The retailer will decide the sales price of unit green packaging products.Green consumers will buy green packaging products according to their purchase intentions.Under this decision-making process,the optimal emission reduction and pricing decision of P enterprise is determined.Through the above analysis,the main research results of this paper are as follows:(1)Consumer low-carbon preference and government subsidies both have positive effects on unit product emission reduction level and P enterprise’s profits,while emission reduction R&D investment has negative effects on unit product emission reduction level and P enterprise’s profits.(2)If P enterprise wants to obtain higher profits and better carbon emission reduction effect,when under certain conditions,the final conclusion is that subsidies based on emission reduction level of unit product will be better than subsidies based on emission reduction research and development cost for P enterprise.(3)Under the two subsidy policies,the imposition of carbon tax will have a certain negative impact on the emission reduction level of enterprises per unit product.Therefore,if the government wants to promote the carbon emission reduction of P enterprise,it should increase the subsidy coefficient.And P enterprise can also promote its carbon emission reduction by choosing better subsidy policies,determining the optimal emission reduction R&D cost coefficient and other methods.
