中文摘要：
分析两个供应链间竞争的系统，每条供应链由一个供应商和一个零售商组成，供应商通过各自零售商销售具有品牌差异的产品，不同品牌产品之间存在替代度，零售商面临不确定性需求．在此系统上，存在供应商间的竞争、零售商间的竞争，和供应链内上下游之间的竞争，三种竞争交织．每条供应链有两种管理库存的方式，即零售商管理库存和供应商管理库存．通过对比不同库存管理方式下系统成员收益，发现，把不确定性需求风险从零售商转移给供应商，并非能增加零售商收益，或减少供应商收益；同时，通过分析了不同库存管理方式对供应链系统竞争均衡状态的影响，指出，在一定条件下，供应商管理库存方式能加强供应商端的竞争，使得零售商和供应商共同受益．
英文摘要：
A competition system of two supply chains is analyzed, where every supply chain is two members, that is, a retailer and a supplier, each selling differentiated brand products through composed of its exclusive retailer, who is faced with uncertain demands. The supplier＇ s competition, the retailer＇ s competition and the vertical interaction between them are all intertwined with each other. Each supply chain can be operated in either the RMI （Retailer-managed inventory） way, in which the downstream retailer decides the inventory level and keeps the inventory, or the VMI （vendor-managed bility and stock level decision switch to the upstream inventory） way, in which inventory-keeping responsisupplier. By comparing the expected payoffs in different cases, we find that transferring demand-uncertainty risk from the retailer to the supplier does not necessarily lead to a higher expected payoff for the retailer or a lower one for the supplier. At the same time, by deriving explicit equilibrium of different supply chain structures, we point out VMI intensifies the competition between suppliers and that the increased competition benefits retailers and suppliers if some conditions are meet.
