Research On Emission Reduction Decision Models For Low-Carbon Supply Chain Based On Behavioral Factors

With the rapid development of economy,climate warming,environmental pollution and other problems are becoming more and more serious.The worsening ecological environment attracts a worldwide attention.In the face of the deteriorating ecological environment,low-carbon supply chain management plays a significant role in promoting the coordinated development of ecological benefits and economic benefits,which is one of the hot research issues at home and abroad in recent years.Almost all the existing researches on low-carbon supply chain are based on the hypothesis of "consumers have low-carbon preference" and totally rational "economic man",which assumes that consumers are willing to buy lowcarbon products and decision-makers are completely rational and self-interested.However,a large number of studies in behavioral economics and experimental economics have proved that the hypothesis of totally rational "economic man" does not hold true in many cases.Actually,the decision-maker is not completely rational,but has the preference of concern for fairness and trust,and pays attention to both their own benefits and the benefits of partners in the decision-making.At the same time,consumers do not necessarily have a preference of low-carbon,and even consumers with a low-carbon preference do not necessarily have a purchase behavior when they are just exposed to low-carbon products or low-carbon information.Therefore,from the perspective of consumer behavior and member enterprise behavior,this paper conducts an in-depth study on the emission reduction decision-making and coordination of low-carbon supply chain.The specific research is as follows:Summarize the issues related to supply chain management for low carbon and the characteristics of low carbon supply chain.This paper introduces the theoriesrelated to low-carbon preference of consumers,concern for equity and preference of trust,and analyzes the effects of consumer behavior and member enterprises’ behavior on low-carbon supply chain emission reduction decision-making.The content and structure among the members of the low-carbon supply chain and research methods are analyzed,and the overall framework of this paper is designed.Aiming at consumers with and without preference behaviors of low-carbon,a low-carbon supply chain decision-making model is constructed and the effect of consumers’ low-carbon preference behaviors on the optimal decision-making system of supply chain is analyzed.Second,under the background that consumer has low carbon preference,low carbon supply chain decision-making model considering the consumer buying behavior is established.Using the theory of differential game,give the optimal decision for members of supply chain under different game structure,the degree of low carbon,brand reputation and profit,and conduct comparative analysis of the effect of consumer purchasing behavior on the optimal reduction strategy formulation for members of low carbon supply chain,and selection of game structure.Considering the basic reality that decision-makers have preferences for equity concerns,the decision-making and coordination of low-carbon supply chain are studied respectively from the perspectives of static and dynamic decision-making.Using the utility function theory,this paper analyzes centralized decision-making and decentralized decision-making with dual fair neutrality and decision-making behavior of supply chain members under fair concern of manufacturer or retailer only and double fair concern of manufacturer and retailer.And this paper also discusses the effect of equity concern degree on the decision-making of low carbon supply chain members.Furthermore,a coordination contract for low-carbon supply chain based on equity concerns is designed,and the impact of the degree of equity concerns on the coordination contract is explored.Considering the trust preference of decision maker,this paper studies the decision-making and coordination of low-carbon supply chain from the perspectives of static and dynamic decision-making.The utility function theory and differential game theory are used to obtain the optimal strategy for supply chain members under centralized decision-making,mutual distrust,manufacturer trust only and decentralized decision-making of mutual trust,and analyze the effect of trust degreeon the decision-making of low carbon supply chain members.Furthermore,a low carbon supply chain coordination contract based on trust behavior is designed.An empirical study is conducted on the low-carbon supply chain of A sportswear brand co.,ltd.and a large department store B.With the low carbon propaganda data of department store B in 2015 for 6 weeks,the sales data of the product and the data of carbon emissions,develop the model of static reduction decision for low-carbon supply chain.Applying the results of the research,this paper proposes the optimal emission reduction strategy for the low-carbon supply chain,and investigates the effect of behavioral preference parameters on the optimal emission reduction strategy and optimal profits,to provide scientific theory basis for giving a strategy of low carbon emissions of supply chain in the future.
