Analysis On Carbon Emission Reduction Decisions Of The Green Supply Chain Dominated By Brand Merchant In Outsourcing Situation

The global economy is paying more and more attention to low-carbon development of enterprises,and consumers’ awareness of environmental protection is also growing.Products are gradually affixed with green labels.The issue of green supply chain management and coordination has attracted more and more attention from enterprises.At present,well-known brands are focusing on projects with their own competitive advantages in operation,and more and more outsourcing part of the non-core business of their products to professional companies.There are more and more government-related carbon policies and higher and higher awareness of low-carbon society.In the environment,brand owners should assume their own corporate social responsibilities for carbon emissions in the whole supply chain.Aiming at the green supply chain dominated by brand owners in the context of outsourcing,I consider the two scenarios of full outsourcing and manufacturing outsourcing,respectively constructs centralized decision-making and decentralized decision-making game models,and obtains the corresponding optimal decision of each subject,and through numerical analysis The impact of consumer carbon footprint sensitivity coefficient,carbon emission reduction cost coefficient and carbon rebate coefficient on the optimal order quantity,total carbon emissions and supply chain profit is discussed.The supply chain contract mechanism was further introduced,and the game model under the cost sharing and benefit sharing contract was constructed respectively,and the corresponding optimal decision results of each subject were obtained.The sensitivity coefficient of consumer carbon footprint,carbon emission reduction cost coefficient and carbon rebate were also explored.The influence of the coefficient on the optimal order quantity,the total carbon emission and the profit of the supply chain under different coordination contracts.The research results show that compared with decentralized decision-making,the carbon emission reduction level of centralized decision-making is higher in both the full outsourcing and manufacturing outsourcing scenarios;at the same time,no matter what decision-making method is adopted,a higher level of carbon emission reduction can be achieved in the full outsourcing scenario.As consumers’ carbon footprints become more sensitive,brand owners can reduce more carbon emissions through full outsourcing compared to manufacturing outsourcing;when decentralized decision-making in a full outsourcing scenario,as the difficulty of carbon emission reduction increases,The total carbon emission of the supply chain has decreased,and the retailers’ optimal ordering volume and the total profit of the supply chain have increased;the brand owners’ carbon rebate incentive system under the fully outsourcing scenario provides the retailer’s optimal ordering volume and the supply chain’s carbon Emission reduction levels and total profits play a positive role.Brand owners’ carbon rebate incentives in the context of manufacturing outsourcing have a negative effect on retailers’ optimal ordering volume,carbon emission reduction levels in the supply chain,and total profits.Under the supply chain coordination contract mechanism,when the cost-sharing or benefit-sharing ratio of retailers and manufacturers meets a certain range,the supply chain carbon emissions and brand profits under the two contracts are different.The impact of the consumer’s carbon sensitivity coefficient on product ordering,supply chain carbon emissions,and brand profits is not much affected by the cost-sharing or benefit-sharing contract;under the cost-sharing contract,the carbon reduction difficulty factor and carbon The change in the rebate coefficient has a greater impact on product ordering,supply chain carbon emissions,and brand owners’ profits.
