Carbon Reduction Decision Of Supply Chain Constrained By Consumer's Low Carbon Preference And Financing

Nowadays,greenhouse gas emissions of carbon dioxide and other greenhouse gases produced by human activities are increasing.The problem of global warming is becoming more and more serious.Some countries and regions in the world have profoundly realized the serious consequences such as sea level rise,atmospheric circulation change and ocean current change.With the coming into force of the Kyoto Protocol,governments have issued various policies to limit carbon emissions,and concept of low-carbon economy and low-carbon supply chain have become hot topics.Due to the rise of the self-media era and the national media publicity on the low-carbon economy,consumers in the product purchase will take more consideration in low-carbon factors.The vast majority of small and medium-sized supply enterprises in China don't have enough money to operate carbon reduction modification to satisfy consumers' need.First,this paper shows the research background,research significance o,literature review,research content and technical line.Next,it indicates the theoretical basis,clarifying low carbon supply chain theory,carbon emissions trading theory,consumer preference theory,supply chain financing theory and game theory.Next,it analyzes carbon reduction decision of supply chain constrained by consumer's low carbon price preference and financing.First,it establishes the consumer low carbon price preference,supplier profit,retailer profit and supply chain total profit model,and then establishes the model in the case of retailer-leader and supplier-leader decentralized decision-making as well as centralized decision-making.Two-stage Stackelberg game is used to optimize the profit maximization as the goal,and the corresponding optimal value is obtained.And the relationship between the optimal value and the parameter is obtained by numerical analysis.At last,it analyzes carbon reduction decision of supply chain constrained by consumer's low carbon demand preference and financing.First,it establishes the consumer low carbon demand preference,supplier profit,retailer profit and supply chain total profit model,and uses two-stage Stackelberg game to solve the problem.The optimal solution is obtained by maximizing the profit.According to the characteristic of the optimal solution,the relationship between the optimal value and the coefficient is obtained by numerical analysis.Research on consumer's low carbon price preference indicates that the increase of low carbon consumer preferences,internal and external financing interest-rate lead to higher gross profit in retailer-leading decentralized supply chain,and the unit cost of carbon emissions and external investment interest-rate will have negative effects on retailer-leading decentralized supply chain's gross profit,while the internal interest-rate is only related to wholesale price in supplier-leading decentralized supply chain.The centralized supply chain gross profit rises as the low carbon consumer price preference increases and the unit cost of carbon emissions decreases.Meanwhile,the centralized supply chain gross profit remains invariable as the internal and external financing interest and external investment interest change.Research on the consumer demand for low carbon preference showed that the optimal carbon emission reduction,the optimal order quantity and supply chain members and overall profit increase with the proportion of financing and financing opportunities yields going up,and decrease with the rising cost of carbon emission reduction units.The optimal profit of the supply chain,the optimal profit of the retailer and the optimal profit of the retailer are independent of the unit carbon emission.In this paper,the analysis of the consumers' low carbon price preference and the low carbon demand preference model can be applied to the actual decision-making to various types of supply chains.
