基于Hotelling模型的港口企业价格比较

Comparative research on prices of port enterprises based on Hotelling model

为了研究多港口的均衡价格,利用Hotelling模型导出了利润最大时的港口均衡价格函数,并以3个港口为例,对不同条件下各港口的价格进行了比较.结果表明:当港口服务水平相同时,地理位置处于中间的港口的均衡价格比较低;当港口服务水平不同时,地理位置和服务水平等因素都会对均衡价格产生影响.

In order to study the equilibrium price of various ports, the function for the equilibrim price with the maximum profit was derived based on the Hotelling model. The prices of three ports under different conditions were compared. The results of the theoretical studies indicate that when the service levels of the three ports are the same, the equilibrium price of the port located in the middle is the lowest, and when they are not the same, the geological positions and service levels have certain effects on the equilibrium prices of the port enterprises.
