摘要
研究了一类基于有限理性预期的古诺双寡头博弈模型,分析了系统不动点的稳定性,并且通过数值模拟系统的分岔图、最大Lyapunov指数图、相图等动力学特性,定性地分析了系统的动力学行为.结果表明,产商为了增加自身利润,不断增大产量调整速度,导致系统经过一系列分岔进入混沌运动状态.因此,市场将失去稳定,变得不可预测.
The cournot duopoly game model based on bounded rationality was studied and discussed the stability of equilibrium points of the system using the dynamical bifurcation theory. Through the numerical simulate the dynamical characteristics of the system, the largest Lyapunov exponents diagram, phase portraits and so on, the dynamic behavior of the system is analyzed qualitatively. The research revealed that with the increase of manufacturer＇s quantity adjust speed, the system through a series of bifurcation into a state of chaos movement. The market will lose stability, and become unpredictable.
