基于Hotelling模型的双寡头市场定价博弈分析

文章在三阶段Hotelling模型的基础上研究了双寡头市场的定价博弈问题。在第一阶段两个寡头企业同时选择价格策略;在第二阶段两寡头企业确定价格大小及相应的定价概率;在第三阶段由消费者选择企业。由博弈分析的结果得出,使用高价和打折相互结合的混合策略为双寡头市场定价博弈的唯一纳什均衡策略,此时博弈双方获得最大利润,即高低价混合策略才是理论推导的最佳策略。文章在最后还从正反两方面给出了这个结论实证上的支持。

A Pricing Game Analysis Based on Hotelling Model in Duopoly Market Fuzhou University

Using a three-stage Hotelling model,we study the problem of price strategies in duopoly market.The duopoly enterprises simultaneously choose their price strategies in the first stage.In the second stage,two firms determine the optimal price and the probability of former price they chose.In the third stage,consumers will finally decide one of the two firms which they purchase from.According to the game theory,we find that the only Nash equilibrium strategy of this problem is mixed strategy.By this way,the tw...
