中文摘要：

针对需求依赖于初始存货量的供应链商业信用期问题展开研究，而在供应链内供应商的决策是商业信用期，零售商的决策是库存水平。通过分析与证明，分别给出了分散决策与集中决策两种情况下，最优商业信用期及库存水平的决策步骤。为了达到渠道协调的目标，提出了利润补偿机制以对渠道内增加的利润进行重新分配。同时模型的性质也通过数值算例进行了详细说明。

英文摘要：

A supply chain model is developed with the assumption that the end demand is initial-stock-dependent and the supplier offers trade credit to the retailer. In the proposed supply chain model the trade credit period is the decision variable of the supplier, and the inventory level decision is made by the retailer. Through analysis and proof, the procedures for determining the optimal trade credit period and the inventory level are provided under non-cooperative as well as cooperative relationships. For the purpose of channel coordination, a profit subsidy policy is presented to divide the increased profit between the channel members. Also numerical examples are presented to demonstrate the properties of the proposed model.
