寡头垄断市场下企业竞争策略

Research on Enterprise Competition Tactics in the Oligopolistic Markets

从博弈双方的有限理性出发,对有限理性双寡头博弈模型进行了定量分析,并将寡头的产量调整速度视为企业的竞争策略,借助数值仿真的方法探讨两企业策略超出稳定域后的利润情况,并将它们与各自均衡利润作比较.结果表明为了使自身利益最大化两企业可以采取合作竞争博弈,经双方反复博弈后市场最终将处于稳定均衡态.

Starting off from the bounded rationality of two game players,a quantitative analysis was made about the duopoly model with bounded rationality. And the adjustment speed of the output quantity is looked upon as the enterprise competition tactics. By aid of numerical simulation the profit performance was put under examination when duopoly strategy exceeds equilibrated region and their respective equilibrium profits were compared as well. The results indicate that enterprises could adopt a strategy in the form of cooperative competition game to maximize their profits,and after a long time of gaming between the two sides the market would gradually stike a balanced state of equilibrium.
