摘要
在两寡头及三寡头垄断市场中假设厂商采用延迟有限理性预期规则,建立动态价格博弈模型,并对该模型进行理论分析和数值模拟,研究不同参数条件下系统的稳定性以及分岔、混沌等复杂性态.数值仿真结果表明,延迟结构本身并不能改善系统的稳定性;采用延迟策略的寡头数目增多或增加延迟期也不一定能使系统稳定性增强.系统稳定性主要取决于延迟变量系数以及其他系统参数的值.
Dynamic game models are established in duopoly and triopoly markets,the firms are presumed to make decisions with delayed bounded rationality.Theoretic analysis and numerical simulations are provided to study the complexity such as stability,fractal and chaos of the system.The results show that more delayed decision mskers and longer delay period as well as delayed structure may not improve stability of the system.System stability mainly depends on the coefficients of delayed variables and other parameters of the system.
