Research On Low-carbon Supply Chain Decision Based On Differential Game Considering Behavior Factors

With the rapid development of economy,the climate issues have become increasingly prominent.In order to alleviate the climate pressure,many enterprises to work together with their partners to build low-carbon supply chains.More and more manufacturing enterprises begin to research and develop the emission reduction technology,produce low-carbon products,and pass the information about carbon emission of products to consumers through advertising or carbon labels,so as to establish good brand image.The research and development of emission reduction technology and advertising is a long-term process,so there is a cumulative effect and the effect is not immediate.The enterprises should formulate pricing,emission reduction and advertising strategies based on a long-term perspective,instead of focusing on short-term profits.In addition,low-carbon supply chain management is mainly carried out by human beings.When building a decision-making model of low-carbon supply chain,the thesis should consider behavior factors of decision makers and consumers that can make the model closer to reality.The conclusions drawn on this basis can better guide practice.At present,there are some research achievements on the decision-making problems of low-carbon supply chain,the decision-making problem of behavioral supply chain and the decision-making problems of supply chain based on differential game,but there are few literature focusing on the decision-making problem of low-carbon supply chain based on differential game considering behavior factors.Therefore,it is of great theoretical and practical significance to study the decision-making problem of low-carbon supply chain based on differential game considering behavior factors.This thesis mainly focus on the decision-making problem of low-carbon supply chain based on differential game considering behavior factors.A series of research works are conducted as follows.(1)The low-carbon supply chain decision and coordination problem based on differential game considering consumers' behavior factors.Firstly,the reference low-carbon level effect of consumer is described.Then,the demand function is established by considering the impact of products'selling price,products'low carbon level,consumers'low carbon preference and reference low carbon level effect on demand.Secondly,a differential game model of supply chain considering consumers' low-carbon preference and reference low carbon level effect is constructed.Furthermore,the supply chain members.optimal emission reduction strategies and present value of profits under centralized decision and decentralized decision are investigated and compared.On this basis,a two-way subsidy contract is proposed,and the influence of consumers' low-carbon preference degree and the effect parameter of reference low-carbon level on the optimal result is analyzed.(2)The low-carbon supply chain decision and coordination problem based on differential game considering behavior factors of consumers and decision makers.Firstly,the products' low carbon level and goodwill are described by differential equations.Then,the demand function is established by considering the impact of products' selling price,products' low-carbon level,consumers' low-carbon preference and products'goodwill on demand.Then,based on the Nash bargaining game theory,the utility functions of the manufacturer and the retailer are given.Secondly,a differential game model of supply chain considering consumers' low-carbon preference and decision-makers' Nash bargaining fairness concerns is constructed.Furthermore,the supply chain members' optimal emission reduction strategies,advertising strategy and present value of profits under centralized decision and decentralized decision are investigated and compared.On this basis,a two-way subsidy contract is proposed,and the influence of the manufacturer's fairness concerns'degree,the retailer's fairness concerns' degree and the manufacturer's bargaining power on the optimal result is analyzed.(3)The low-carbon supply chain decision problem based on differential game under different power structures.? Firstly,the consumers' low-carbon preference and heterogeneity is described.Then,the utility functions of different types of consumers are given so as to obtain the demand function of low-carbon products.Secondly,a differential game model of supply chain considering consumers' low-carbon preference and heterogeneity is constructed.Furthermore,the supply chain members's optimal emission reduction strategies,pricing strategies and present value of profits under different power structures are investigated and compared.And the influence of the proportion of environment-friendly customers in the market on the optimal result is analyzed.?Based on(2),only product sales price,low carbon consumer preferences and product reputation effect on demand are considered and a similar differential game model is built.Then,supply chain solution and to compare the supply chain under different power structure members of the present value of the optimal reduction strategy,pricing strategy and profits,and analyzes the influence of key parameters on the optimal results.Furthermore,the supply chain members' optimal emission reduction strategies,pricing strategies and present value of profits under different power structures are investigated and compared.And the influence of key parameters on the optimal results is analyzed.(4)The low-carbon supply chain decision and coordination problem based on differential game considering behavior factors in competitive environment.Firstly,the products'low carbon level and goodwill are described by differential equations.Then.the demand function is established by considering the impact of products' selling price,consumers' low-carbon preference and products' goodwill on demand.Secondly,a differential game model of supply chain considering consumers' low-carbon preference is constructed.Furthermore,the supply chain members' optimal emission reduction strategies,pricing strategies,advertising strategies and present value of profits under centralized decision and decentralized decision are investigated and compared.On this basis,a mixed contract of revenue sharing and cost sharing is proposed,and the influence of low-carbon competition intensity and advertising competition intensity on the optimal result is analyzed.(5)The low-carbon supply chain decision problem based on differential game under the cap and trade policy.Firstly,the thesis describes consumers' low-carbon preference and heterogeneity,and gives the utility functions of different types of consumers when they purchase ordinary products and low-carbon products,so as to obtain the demand functions of ordinary products and low-carbon products.Then,differential game models based on different production modes under the cap and trade policy considering consumers'low-carbon preference and heterogeneity are constructed.Furthermore,the supply chain members' optimal emission reduction strategies,pricing strategies and present value of profits under ordinary production mode,mixed production mode and low carbon production mode are investigated.On this basis,the manufacturer's optimal production mode is discussed,and the influence of carbon trading price on the optimal result is analyzed.
