Research On Motivation Of Supply Chain Carbon Emission Transfer And Network Equilibrium Under Heterogeneous Carbon Trading Policy

With the introduction of carbon regulations,reducing carbon dioxide emissions has become an important issue facing many companies.In order to reduce carbon emissions,companies will not only implement strategies such as investment reduction and production reduction,but also may transfer carbon dioxide emissions to upstream and downstream companies to transfer supply chain carbon emissions.The transfer of carbon emissions in the supply chain not only obscures the responsibility of reducing emissions among enterprises,but also brings difficulties to the entire human society in reducing emissions.In order to study the internal mechanism and related effects of the carbon emission transfer of supply chain enterprises.In this paper,first,under the heterogeneous carbon trading policy,considering the differences in emission reduction technology level,by constructing a supplier-led Stackelberg game model,this paper explores the motivations of supply chain carbon emission transfer and according to the formation conditions and conditions of carbon emission transfer.Classify the impact of total carbon emissions in the supply chain;then,formulate a technology sharing contract to coordinate and optimize the supply chain;finally,summarize the impact of carbon emissions transfer into carbon emissions transfer amplification effects and technology spillover effects.The establishment of a hyper-network equilibrium model under heterogeneous carbon trading policies studies the influence of expansion effects and technology spillover effects on supply chain members' pricing,profits,and total carbon dioxide emissions.The specific research content and conclusions of this article are as follows:(1)Construct a game model with or without carbon emission transfer.By comparing the income of companies in the two situations,the motivation for carbon emission transfer in the supply chain is obtained.The carbon emission transfer is classified according to the impact of carbon emission transfer on the environment.Corresponding optimization and coordination strategies are proposed for different types of carbon emission transfer.Research shows that when the manufacturer's emission reduction technology level is higher than that of the supplier,the carbon price faced by the manufacturer is lower than that of the supplier,the difference in carbon trading prices between the supplier and the manufacturer and the difference in carbon emission reduction levels meet certain conditions.Businesses have carbon transfer motives.Supply chain carbon transfer may lead to an increase in the total carbon dioxide emissions of the supply chain,or it may lead to a reduction in total carbon emissions.Under certain conditions,the Pareto improvement of supplier profits,manufacturer profits,and total carbon dioxide emissions in the supply chain can be achieved by building a technology sharing contract between carbon emission transfer supply chain companies.(2)Constructed a network equilibrium model composed of suppliers,manufacturers,retailers and demand markets,and obtained the equilibrium conditions of each layer of the supply chain and the entire network using the method of variational inequality.In the numerical analysis,first analyze The impact of changes in supplier-level carbon trading prices and manufacturer-level carbon trading prices;then separately analyzed the effects of carbon emissions expansion and emission reduction technology spillover effects;finally discussed the combined effects of carbon emission expansion effects and emission reduction technology spillover effects.Studies have shown that the increase in carbon prices in the supplier-level carbon trading market will lead to an increase in carbon dioxide emissions from suppliers and manufacturers;the increase in carbon prices in the manufacturer-level carbon trading market will lead to a reduction in carbon dioxide emissions from suppliers and manufacturers.The stronger the carbon emission expansion effect,the higher the demand market sales price,the lower the product production and sales,and the higher the total system carbon dioxide emissions.When the spillover effect of emission reduction technology increases,companies will reduce sales prices and increase production to obtain higher profits,but the total carbon dioxide emissions of the supply chain will not increase.Only when the expansion effect of carbon emissions remains within a certain range,through increasing emission reductions The technology spillover effect can make the economic and environmental benefits of all members of the supply chain be better than the situation when there is no carbon emission transfer.
