| 摘 要： | 借用生态学中模拟种群动态关系的LV模型,构建同一港口群内港口间的竞争与互利模式,通过对其定态的稳定性分析,得到非均衡市场下港口市场结构状态和港口竞争双赢、互利双赢的形成条件,并就港口竞争、互利关系的历史演变作相关探讨分析,以期为港口的健康发展和规划管理提供决策参考.

| Abstract: | An attempt is made to analyze the competition and mutualism among ports in the same port group by adopting the nonlinearity dynamic LV model which simulates the population dynamic relation in ecology,and two models are built to describe them.The model's stability is analyzed to give the states and the conditions of market structure and win-win of competition and of mutualism in an non-equilibrium market.The historical evolution about competition and mutualism among ports is discussed in order to give more knowledge for healthy port development and planning management. |
