摘要
在市场信息不对称的条件下,市场参与者将会采用不同的产量决策。在此假设下,本文建立了不同理性双寡头博弈模型,并对其进行了定性分析。详细探讨了系统Nash均衡点的存在性和稳定性。并数值仿真了不同的市场参数条件下的系统动态行为。研究发现寡头为了获取前期竞争优势而不断加快产量调整速度,将会导致系统的不稳定,进而使系统陷入混沌状态。
Under the anisomerous condition of the market information, players will choose different output decisions. On this assummption, this paper builds a duopoly game model with heterogeneous expectations, and analyzes the model. We study the existence and stability of this system＇ s Nash equilibrium. Then show the complex dynamics of this system in different market parameters though numerical simulation. When the player accelerates the adjustment speed of the output quantity in order to achieve initial advantage, we discover that it leads to instability of system and makes the system sink into the chaotic state.
