Research On Contract Mechanism Design Of Dual-Channel Low-Carbon Supply Chain Under Different Power Structures

With the rapid development of economy and technology,while mankind is creating wealth,it has also brought great damage to the environment.The natural environment is closely related to the survival of human beings,and environmental issues have caused widespread concern in the world.After China issued a series of low-carbon policies,initial progress has been made in reducing emissions.However,the environmental situation is still severe,and energy conservation and emission reduction are still inevitable problems for enterprises.At the same time,with the development of the Internet,online shopping has become a part of people’s lives.More and more companies will not only sell products in traditional retail channels,but also hope to increase market demand for products and improve their competitiveness through opening up network channels.Therefore,when designing a dual-channel supply chain model,this article adds consideration to product greenness,which is more realistic.In addition,in the actual operation of the dual-channel supply chain,since manufacturers and retailers are "rational economic people",both are pursuing the maximization of their own interests,often leading to double marginal effects.Therefore,on the basis of analyzing and summarizing domestic and foreign research on dual-channel supply chain,this paper takes the dual-channel supply chain composed of a manufacturer and a retailer as the research object,and uses Starkberg game theory and mathematical modeling to analyze Research on pricing decision and contract coordinationmechanism of dual-channel low-carbon supply chain under different power structures.Combined with actual cases,the feasibility and rationality of the conclusions are verified.The main conclusions obtained in this article are as follows:(1)The higher the consumer ’s preference for low-carbon,the more it helps companies to increase investment in low-carbon emission reduction technologies.For the government,strengthening low-carbon publicity and raising consumers’ awareness of low-carbon consumption is an effective way to promote corporate emissions reduction.(2)The dual-channel low-carbon supply chain under different rights structures can resolve conflicts and conflicts through the contract model to achieve supply chain coordination.The dual-channel supply chain led by the manufacturer can coordinate the supply chain through cost sharing contracts,revenue sharing contracts,and two pricing contracts.The traditional revenue sharing contract cannot coordinate the dual-channel low-carbon supply chain led by retailers.However,the retail-led dual-channel supply chain can coordinate the supply chain through cost-sharing contracts and two pricing contracts.(3)Impact of different power structures From the perspective of the members of the supply chain,the members with the dominant power will make the decisions that are most beneficial to them,and ultimately obtain greater benefits.The change in the power structure of the supply chain will also affect the pricing decision of products and the degree of greenness.(4)Leaders of different rights structures can choose to use the two-part pricing contract to maximize returns.
