Research On Low Carbon Fabric R&D Decision Of Apparel Supply Chain Based On Game Theory

The achievement of the carbon peak and carbon neutrality goals is a broad and profound transformation of the economic and social system that is taking place.However,fast fashion is becoming more and more popular in the clothing industry,and its low carbon environmental protection problem is becoming more and more prominent,which has attracted the attention of relevant enterprises and institutions.At the same time,this phenomenon affects people’s life and cognition.Clothing enterprises also pay more and more attention to the low carbon performance of clothing fabrics.However,the development of low-carbon fabrics for clothing by some small and medium-sized enterprises is constrained by the issue of funding,so the research on the development strategy of low-carbon fabrics for suppliers and brands constrained by funding in the clothing low-carbon supply chain has important practical significance.The study uses a game theory approach to investigate the low carbon fabric R&D decision problem of small and medium-sized suppliers and brand owners.A Stackelberg game model of low carbon fabric R&D decision in the apparel supply chain led by brand owners is established,in which suppliers are subject to financial constraints.In the model,two ways of supply chain financing and cost-sharing contract are introduced to solve the supplier’s financial problem,and the optimal revenue function and supply chain low carbon level of four different strategies of the supply chain and brand owners are calculated according to the inverse induction method,and the evolutionary game payment matrix is constructed with the optimal revenue function of the four strategies to calculate the replication dynamic equation of low carbon fabric R&D decision of the supplier and brand owners for evolutionary game Stabilization strategy analysis.Numerical simulations are conducted to verify the validity of the two game models and propose feasible suggestions to suppliers and brands from different perspectives.The research finds that: no matter from the perspective of short-term or long-term development,only one of the members of the supply chain enterprises can increase the income of the supply chain enterprises by developing low-carbon fabrics;From the perspective of short-term development,both cost sharing contracts and supply chain finance can solve the problem of suppliers’ fund shortage.From the perspective of long-term development,compared with cost sharing contracts,supply chain finance is suitable for solving suppliers’ fund problems;When consumers are not sensitive to low carbon clothing products and low carbon technology development is not mature,one of the supply chain enterprise members can gain more benefits by developing low carbon fabrics.When consumers have a low carbon preference for clothing products and low carbon technology is relatively mature,suppliers’ loan to brand merchants to develop low carbon fabrics is a stable strategy;Consumers’ low-carbon preference has a positive impact on the income of supply chain enterprise members.Brands should pay more attention to consumers’ preferences in the market.
