中文摘要：

基于参考价格依赖的需求模型,分析了受价格管制的厂商利润最大化问题,构建了同时考虑参考价格效应与价格上限管制的厂商定价模型,分别给出了仅考虑参考价格效应与同时考虑参考价格效应与价格管制的厂商最优定价策略与最优质量控制策略的显性解,分析了价格上限管制对产品或服务的价格、质量以及质量价格比的影响.研究结果表明,当厂商的价格处于价格管制阶段,厂商倾向于通过降低产品或服务质量方式来降低成本支出,部分弥补由于价格管制而带来的收益损失;在价格下降质量下降的同时,厂商提供的产品或服务的质量价格比降低,即消费者消费单位质量的产品或服务的价格上升;管制价格越高,质量和质量价格比的下降幅度越小.

英文摘要：

Taking the reference price effect into consumer demand analysis,an analytical model aimed at solving the profit maximization problem of a firm under price cap regulation is developed,enabling the explicit solutions（optimal price and optimal quality） to be depicted.Comparing with the situation without price regulation,the effects of price cap regulation on the price,quahty and quality-price ratio are analyzed,respectively.The results show that under price cap regulation the firm is prone to provide lower-quality product or service for reducing cost and making up for part of the lost revenues due to price regulation;The quality-price ratio declines when the price and the quality decline,which means that consumers must pay more for per-quality product or service;The higher the regulated price,me lower the decreasing amplitude of quality and qualityprice ratio.
