Research On Coordination And Evolutionary Strategy Of Sustainable Supply Chain Financing

As global environmental issues become more prominent,public awareness of environmental issues and corporate social responsibility are increasing.The concept of “triple bottom line” requires companies to balance economic,environmental and social dimensions simultaneously to ensure that business operations have a positive impact on the natural environment,society and long-term economic benefits,and bring long-term competitive advantages to the company.Therefore,sustainable supply chain management has become an important research topic to deal with economic,environmental and social issues.This paper takes the upstream supply chain composed of supplier-manufacturer and the downstream sustainable supply chain composed of manufacturer-retailer as the research object to explore the sustainable supply chain financing coordination and evolutionary strategy related to economy,environment and society respectively.This paper first constructs game decision models of sustainable supply chain under various power structures for upstream supply chain.By applying Stackelberg,vertical Nash and Nash bargaining game theory,this paper explores the centralized decision-making,decentralized decision-making and cooperative decision-making behavior of game participants in the game system.On this basis,this paper further establishes a model based on two-part tariff coordination contract,and analyzes the product sustainable level,price and enterprise profit under the optimal cooperation mechanism.At last,this paper further studies the influence of consumer sustainable product sensitivity and microfinance interest rate on the decision-making and profit of supply chain enterprises through a numerical analysis.The analysis shows that the proposed optimal cooperation mechanism can eliminate the negative impact of high microfinance interest rate.Finally,this paper expounds the practical significance and management insights of the cooperative decision on the improvement of supply chain economy and environmental performance.Another research focus of this paper is the sustainable evolution behavior and related strategic issues of downstream supply chain enterprises under the government’s low-carbon policy and emerging low-carbon market.A two-level supply chain composed of a retailer and a manufacturer is established.Stackelberg game is used to solve the supply chain system under four different sustainable product strategy combinations.Then evolutionary game is used to analyze the stability of the four strategy combinations,and ESS is determined.The ESS shows that at least one supply chain enterprise will take the initiative to take sustainable actions,which not only meets the low-carbon requirements of the government,but also meets the sustainable consumption demand,achieving the economic,environmental and social Pareto improvement.Finally,the paper further discusses the impact of government’s lowcarbon policy change,consumer sensitivity and retailer’s carbon financing interest and subsidy rate on ESS,and puts forward long-term operation strategies and management insights for supply chain enterprises and low-carbon policy suggestions for the government managers.
