碳限额交易机制下低碳供应链协调策略

A Coordination Strategy of Low Carbon Supply Chain under Cap-and-trade Mechanism

为实现低碳供应链的完美协调,在碳限额交易机制下构建由一个制造商和一个零售商组成的两级供应链。运用博弈论的方法,求得集中和分散决策下的最优决策。然后以此为基准,提出2种协调契约。最后通过数值仿真分析相关参数对均衡结果的影响。研究发现,收益共享−成本分担契约不能实现供应链的完美协调,而批发价格−成本分担契约能实现供应链的完美协调。此外,政府应加强环保宣传力度,培养消费者的低碳意识,同时也应合理控制碳价,平衡供应链成员利润。

In order to achieve the perfect coordination of the low-carbon supply chain,a two-level supply chain consisting of a manufacturer and a retailer is constructed under the carbon cap-and-trade mechanism.Using the method of game theory,the optimal decision under centralized and decentralized decision-making is obtained.Then,based on this,two coordination contracts are proposed.Finally,the influence of relevant parameters on the equalization result is analyzed through numerical simulation.The study finds that the revenue sharing-cost sharing contract cannot achieve the perfect coordination of the supply chain,but the wholesale price-cost sharing contract can.In addition,the government should strengthen environmental protection publicity and cultivate consumers'low-carbon awareness.At the same time,it should reasonably control carbon prices and balance the profits of supply chain members.
