基于双寡头竞争的分层服务模型及最优定价策略

Tiered Service Model and Optimal Pricing Strategies for Duopoly Competition

过去几年全球移动数据流量呈现爆炸式增长,而运营商的流量业务却陷入增量不增收的窘境。考虑到不同类型的消费者,提出适合双寡头竞争市场的分层服务模型,即运营商根据带宽需求和数据传输优先级对用户进行分类,并按照高优先级接受高质量服务的原则为用户提供差异化服务。另外,按照运营商采取分层服务模型和非分层服务模型将双寡头竞争分为4种策略局势,并研究了不同策略局势下,运营商的最优服务定价和最大收益问题。研究对运营商的策略选择和定价决策具有一定的参考意义。

The mobile data traffic has experienced an explosive growth during last decade. However,the revenues of mobile operators increase slowly with the rapid growth of mobile traffic. Therefore,consumers are divided into different types,a tiered service model is developed for different types of users in duopoly competition. That is,the mobile operators classify users into different patterns according to their bandwidth demand and priority,and thereby provide them differential service levels with rules of higher priority receiving higher quality service. Furthermore,the duopoly competition is extended to four kinds of strategy profiles according to their choices of adopting tiered service model or not,then optimal pricing and maximal revenue for mobile operators are studied under different strategy profiles. Our research would be of interest to mobile operators in selecting appropriate strategies and determining optimal price.
