中文摘要：
通过Hotelling模型推导出港口的需求、利润函数,在此基础上构建了港口竞争合作模型,研究了在不同条件下,港口的演化稳定策略.研究表明：港口之间长期竞争合作演化的均衡结果是完全竞争或者是完全合作;港口收敛于哪一个均衡点与港口的服务水平、港口的位置、陆上运输费率等因素密切相关.
英文摘要：
In this paper,we deduce demand function of port based on Hotelling model,then build competition-cooperation model of two ports,finally we study the evolutionary stable strategy of the model with different constraint conditions.Research indicates with different constraint conditions,that the long-term equilibrium result of ports system is competition or co-operation.With information guideline mechanism,the initial situation influences equilibrium point the ports converge at.And the path chosen and developed state are closely related to ports＇ service levels,ports′ locations,land freight rate etc.
