为了研究引入供应商竞争对基于收益共享的寄售模式下供应链收益的影响,针对含两供应商和单零售商的供应链结构,分别构建收益共享寄售契约下的集中决策、完全分散决策和供应商联合决策模型,分析了这三种情境下供应商竞争对系统最优决策和均衡收益的影响,并比较了它们的供应链绩效.结果表明,集中决策下的供应链收益始终优于完全分散决策和半分散决策.当供应商之间的竞争较小时,供应商采取联合决策只能改善其自身收益,会损害供应商和供应链整体的收益;而当供应商竞争较大时,供应商联合决策可以实现供应链各方收益的Pareto改进.进一步给出三种决策情境下供应链收益对需求价格弹性和交叉价格弹性的敏感性分析.

英文摘要：

Aiming at the supply chain structure consisted of two suppliers and one retailer,three models associated with centralized decision-making,total decentralized decision-making and partially decentralized decision-making under consignment contracts with revenue-sharing were formulated.The effect of suppliers＇ competition to the optimal decisions and revenue equilibriums of those three models was demonstrated and the channel performance was compared as well.The comparison result showed that the chain-wide profit under the centralized decision-making was superior to the other two models.Without intensive competition,suppliers＇ joint action could only improve the suppliers＇ profits but ruin the retailer＇s and even chain-wide profits; however,with intensive competition,suppliers＇ joint action could achieve Pareto improvement for all participants.A sensitivity analysis of supply chain revenue for pure and cross demand-price elasticity was also conducted.
