低碳偏好下三级供应链协调策略研究

以一个零售商为领导者、一个制造商和一个供应商为追随者组成的三级低碳供应链为研究对象，应用微分对策理论，考虑低碳偏好和产品商誉下研究下游零售商低碳宣传、上游制造商和供应商联合减排的低碳供应链优化与协调问题。研究发现，零售商、制造商和供应商选择何种博弈策略与三者的边际收益率有关；当供应链上三个主体的边际收益率满足一定条件时，成本分担契约可以促进零售商、制造商、供应商以及供应链系统整体的Pareto改进，使各自的最优利润得到改善，改善的程度等于成本分担的比例，而成本分担的比例取决于双方的边际收益率。最后，通过算例对模型进行了分析。

Research on Joint Emission Reduction and Low Carbon Publicity Strategy for Three-Level Low Carbon Supply Chain

This paper takes a three-tier low-carbon supply chain consisting of a retailer as a leader, a manufacturer and a supplier as followers as the research object, and applies the differential countermeasure theory to study the problem of optimization and coordination of the low carbon supply chain between the low-carbon propaganda of downstream retailers and the joint emission reduction of upstream manufacturers and suppliers. The paper found that which game strategy will retailers, manufacturers and suppliers choose is related to the marginal rate of return of the three; when the marginal rate of return of the three subjects in the supply chain meets certain conditions, the cost-sharing contract can improve the Pareto of the overall profit of retailers, manufacturers, suppliers and supply chain systems, and the degree of improvement is equal to the proportion of cost sharing. And the proportion of cost sharing depends on the marginal rate of return of both parties. Finally, the model is analyzed by an example.
