中文摘要：

基于消费者对相似产品的不同支付意愿,研究了零售商补货及反应性定价策略。通过两阶段模型的建立和求解,找出反应性定价的规律并确定产品的补货量。归纳了在清仓定价（延迟定价的特例）和无延迟定价下零售商的定价和补货策略。借助数值仿真,讨论了市场波动性和产品接受度对最优决策及利润的影响并比较了不同定价模式（反应性定价、清仓定价、无延迟定价）的影响。

英文摘要：

This article investigates the retailer＇s optimal replenishment and responsive pricing strategies in a heterogeneous market where consumers have various utilities over similar products. We find the optimal pricing and replenishment quantities in analyzing a two-stage model.We also demonstrate the replenishment strategies when the retailer adopts market clearance price（a special case of price postponement） or no-postpone price.Through numerical examinations,we explore the effects of different parameters on the retailer＇s replenishment quantities and profit in these different pricing modes（responsive,clearance and non-postpone pricing）.
