经济主体在市场中的行为通常只能依赖于不完备的信息,但是即使如此,每个经济个体还是会根据所处的宏观环境修正自身的行为策略以提高收益状况,从而构成市场行为进化中的宏观结构与微观行为相互影响的自组织现象;所谓市场的“习惯”正是这种自组织进化的结果;但是,由于信息的不完备和初始条件的不同,使得通过自组织形成的市场规范不一定会达到最优状态;因此,必要的干预是不可缺少的。本文以出租车市场为例,利用一个进化对策模型模拟了市场行为的进化规律,并通过对参数的讨论分析了控制市场行为进化方向的策略与方法。
However, even in this way, each economic entity will revise its own behavior strategy according to the macro-environment in which it is located so as to improve the profitability and thus constitute the evolution of the market behavior The macro structure and micro behavior affect each other’s self-organization phenomena; the so-called market “habit” is the result of such self-evolution; However, due to incomplete information and initial conditions make the formation of market regulation through self- The state of affairs will surely be reached; therefore, the necessary intervention is indispensable. Taking taxi market as an example, this paper uses an evolutionary countermeasure model to simulate the evolution of market behavior and analyzes the strategies and methods of controlling the evolution of market behavior through discussion of parameters.
