基于回收物流成本的不同权力结构闭环供应链决策研究

针对回收物流成本要素对不同权力结构闭环供应链及其节点企业决策的影响问题，运用博弈论方法构建了由制造商和零售商组成的集中式决策闭环供应链，以及分散式决策闭环供应链模型。研究表明：在分散式决策闭环供应链中，消费者更倾向于零售商主导的市场结构；仅仅考虑零售价格，消费者会更加偏好于集中式的闭环供应链市场结构；制造商承担回收物流成本增加产生的利润损失会转嫁给零售商，并且导致零售商直接提高产品销售价格而引起市场废旧品回收率的降低。Nash均衡状态容易受到制造商和零售商利己行为的影响，占据主导地位的一方会打破市场的均衡状态。通过算例计算，对比分析了回收物流成本变动对回收率、销售价格、批发价格，以及闭环供应链节点企业最优利润的影响。

Research on the Decisions of Closed-loop Supply Chain of Different Power Structure Based on the Recycling Logistics Costs

Aiming at the influence of recycling logistics costs on the different power structure closed-loop supply chain and its node enterprises,the centralized decision-making closed-loop supply chain model and decentralized decision-making closed-loop supply chain models,which consistsof manufacture and retailer,were constructed with game theory.The results indicate that consumers prefer retailer-dominated market structure under decentralized closed-loop supply chain and prefer centralized closed-loop supply chain if only considering the retail price;the loss of profits will be passed on to retailer with the increases of return logistics costs undertook by manufacturers,and lead to the declineof waste products recovery rate resulting from the retailer’s increase of the retail price.The Nash equilibrium is easily destroyed by manufacture and retailer selfish behavior,so the dominant party will break the equilibrium state of the market.By using numerical analysis method,the impact of recycling logistics costs on return rate,retail price,wholesale price and optimal profits of closed-loop supply chain node enterprises are compared and analyzed.
