绿色供应链下的收益共享契约机制研究

Research on Revenue Sharing Contract in Green Supply Chain

研究一个由供应商和零售商组成的两级绿色供应链的协调机制问题。建立两级绿色供应链下的分散决策、集中决策和收益共享契约机制模型,并给出各模型下的最优均衡策略。最后,通过数值例子对模型进行比较分析,并对分析结论进行验证。结果表明,在绿色供应链中,随着绿色产品绿色度的增加,绿色产品的涨价率会提高,零售商的产品订购量将会减少,供应链各成员的利润先减小后增加,而且各成员在收益共享契约机制下利润相比其在分散决策时有明显提高。

The supply chain coordination mechanism of a two-stage green supply chain composed of one supplier and one retailer is studied. Models of decentralized decision, centralized decision and revenue sharing contract are constructed, and their optimal policies are also proposed. Finally, a numerical example is given to illustrate and validate the models and conclusions. It is shown that in the green supply chain, with the raise of the green degree of the green product, the mark up rate of the green product will increase, the order quantity of the retailer will decrease, and the profits for each member will firstly decrease and then increase. In addition, the profits for each member in revenue sharing contract can be improved remarkably compared to in decentralized decision.
