基于两阶段信号博弈的港口合作声誉模型

Port cooperation reputation model based on two stage signal game

运用博弈论与信息经济学理论,建立基于港口价格与服务时间的两阶段信号博弈的声誉分析模型,推导出港口在利用信号博弈时的均衡价格信号和均衡服务时间信号及均衡条件下的最大效用.通过理论分析得出,港口在第1阶段建立声誉会提高第2阶段的价格信号强度、服务时间信号强度和效用.最后通过具体算例对上述模型进行分析,结果表明:港口利用合作声誉可以获得更大的效用,为引导港口间加强合作关系、实现区域港口群对外竞争力的提高和区域港口共赢提供参考依据.

With game theory and information economics theories, a two stage port cooperation reputation model is presented based on price and service time signal game. The port＇ s optimal price signal, service time signal and utility when the port uses signal game are derived. It can be shown from theoretical analysis that theport＇s optimal price signal strength, service time signal strength and utility at the second stage are larger if the port sets up reputation at the first stage. At last, a numerical example is given to analyze the proposed model. It is shown that more utility can be achieved when a port uses reputation, which provides references for strengthening port cooperation, improving port competitiveness and achieving win-win among ports.
