中文摘要：

文章构建了一个需求依赖价格和销售努力水平情形下强势零售商的定价订货模型，通过研究分析海塞矩阵发现期望利润函数是凹的，所以最优定价、订货策略及销售努力水平存在且唯一；最后使用一个算例来演示最优解的计算过程。

英文摘要：

A model to solve pricing and ordering problem for a dominant retailer with price and sales ef- fort dependent demand is constructed. The maximum expected profit function is proved to be continu- ous concave by the analysis of Hessian matrix, so the optimal solution to pricing and ordering policy and sales effort level exists and is unique. A numerical example is given to show the computing process of obtaining the optimal solution.
