港口竞争合作策略的演化博弈分析

Evolutionary Game Analysis of Port Competition Cooperation Strategy

为了研究港口之间长期的竞争合作关系,在完全信息条件下的竞争合作静态博弈模型基础上,采用演化博弈的理论方法,分析了港口竞争合作长期演变发展的趋势。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完全合作;在一定的信息引导机制下,港口收敛于哪一个均衡点受到博弈发生的初始状态的影响;从何路径最后达到何种状态与港口间的服务替代率密切相关。

In order to investigate long term competition and cooperation relationship among ports, evolutionary game method is adopted to analyze long-term evolutionary development trend of relationship among ports, based on the results of static game model in the condition of complete information. It is indicated by the research that the consequence of probable equilibrium resulted from long-term competition and co operation among ports is either complete competition or complete cooperation. Under a certain information guideline mechanism, the initial situation when game starting will influence the equilibrium point to which ports converge. And through what path to attain what state finally is closely related to the service substitution rate among ports.
