中文摘要:在随机需求环境下，电信企业的价格策略表现为一个随时变化的调整轨迹，将寡头电信企业之间的价格竞争博弈刻画为微分博弈模型，并对模型进行了数值模拟和仿真分析，结果表明：在随机需求下，寡头电信企业的价格策略存在唯一的鞍点均衡路径，否则很难实现均衡状态；虽然寡头电信企业的价格处在动态调整中，但市场份额会相对稳定维持在某一均衡状态下。

Modeling and Analysis of Telecom Oligopoly Pricing as a Differential Game

Abstract:In stochastic demand environment, the telecommunications company's pricing strategy keeps changing at any time. The price competition process of telecom oligopolies is characterized as a differential game model in this paper. After simulation analysis, it is found that there is only one saddle equilibrium point in their pricing strategies, otherwise it's not easy to realize equilibrium state. Althought the prices of telecom oligopoly are changing, their market shares are kept stable.
