碳税政策下基于成本分担的供应链协调研究

Study on Supply Chain Coordination under Carbon tax Policy Based on Cost- sharing

针对由一个制造商和一个零售商组成的两阶段供应链结构,研究碳税政策下的供应链协调问题。首先,在碳税成本由零售商完全承担的情况下,分别分析供应链集中决策和分散决策的最优采购量决策,证明分散决策下的最优采购量低于系统最优水平,从而降低供应链的整体利润,在此基础上,设计碳税成本分担契约,使得分散决策下供应链期望利润达到了集中化供应链的效率,实现环境制约下的供应链协调。

In a single -manufacturer -single -retailer＇s two -echelon supply chain system,we study the problem of sup-ply chain coordination under carbon tax policy.Firstly,under the condition that the carbon tax cost is fully borne by the re-tailer,we analyze the optimal order decisions under supply chain centralized and decentralized decision.We prove the op-timal order quantity under decentralized decision is lower than under the centralized decision,thereby the decentralized de-cision reduces the overall profit of the supply chain Based on this,we design the carbon tax cost -sharing contract,then we make the supply chain expected profit under decentralized decision reaches the efficiency under centralized decision,and a-chieve the supply chain coordination under environmental constraints.
