摘要 有别于传统思路,本文用LotkaVolterra动力学系统对市场演变进行分析,从而避免了市场必须处于均衡状态的假设。通过对市场上各种产品之间相互关系的模拟,构建市场的演进模型,并进行稳定性分析,以此得到市场结构的各种状态及其形成条件。模型的结论除了涵盖市场均衡下的传统理论之外,还可以描述市场非均衡状态。由此,本模型更具有一般性。 Different from classical thoughts, this paper analyses the evolution of market structure with “Lotka-Voherra” dynamic system, so avoids the prior hypothesis of market equilibrium. By simulating the relations of product in market, a model of market structure be established. The analysis of model's stability gives the states and the conditions of market structure come into being. From the conclusion,the classical theory under equilibrium states is included by this model, and the state of non-equilibrium market is can be described as well.So, this model is more universal.
