押金补货是指零售商在第一阶段向供应商交纳一定的押金,在接下来的阶段中不需要再交纳额外的补货费用的补货方式。对于中小型零售商,它的补货策略往往受到自有资金的约束,当自有资金不足以订到报童模型的最优补货量时,不仅自身收益受到影响,还会影响到整条供应链的收益,本文研究了在随机市场需求,且零售商能够随时向银行贷款的情况下,基于收益共享契约的零售商的押金融资订货策略。本文从两阶段出发,分析零售商的最优订货策略,研究表明,零售商的补货策略受初始资产和收益共享系数的影响。最后,文章将其扩展到多阶段问题进行讨论。

英文摘要：

Deposit replenishment strategy means that the retailer pays some deposit to suppliers in the first period, and the supplier automatically replenishes to the retailer according to the retailer＇s deposit amount in the first period. For the small or medium sized retailers,their replenishment strategies are often restricted by their own funds,where their own funds are usually not sufficient to meet the optimal newsboy model. We find that the retailer＇s optimal replenishment quantity affects not only his own revenue,but also the profit of the whole supply chain. We study the problem that the retailer faces the stochastic market demand under revenue-sharing contract. We suppose that the retailer can always ask for the bank loans when needed. This article studies the twoperiod problem and shows that the retailer＇s optimal replenishment strategy is influenced by both his initial capital and the revenue sharing coefficient. Finally,we extend the two-period problem to multiple period problems and discuss the optimal decision accordingly.
