碳限额政策约束下基于收益共享契约的两级供应链协调

Two-echelon Supply Chain Coordination with Carbon Quota Constraint Based on Benefit Sharing Contract

研究了在碳限额为外部限制条件下的两级供应链协调问题。通过对供应链共享契约的合理设计,实现在碳限额政策下的两级供应链协调,实现企业间的利润共享、风险共担,提升供应链整体利益。通过对上述问题的研究,得到了如下结论:在考虑收益共享契约的两级供应链协调下,一定存在一个比成本更低的批发价,此时,生产商的利润全部来自于销售商的收益共享中;由于政府碳限额的存在,生产商在碳限额条件下的产品最优供应量小于在非约束条件下的最优供应量;在碳限额情形下,收益共享契约当中的最优批发价格高于无限额情形下的最优批发价格的同时,零售商在此情形下会增加收益的保留比例来维持自己的收入水平。

In this paper, we studied the coordination of a two-echelon supply chain with carbon quota as the external constraint, then by designing a suitable supply chain sharing contract, coordinated the two-echelon supply chain under the carbon quota policy, shared the supply chain benefits and risks among the enterprises, and at the end, reached and elaborated on the conclusions reached.
