基于Hotelling模型拥挤港口的定价研究

摘要

In this paper,we consider port pricing model in combination port congestion (vertical differentiation)with Hotelling model (horizontal differentiation ).Under the mild assumption,that is,customers' distribution following uniform distribution,the equilibrium pricing strategies of ports are accurately characterized by Nash equilibrium.The results show that,the higher investment level of the ports incurs the higher capacity of the ports as well as marketing share,and thus the profit of the port increases.%文中将港口拥挤（垂直差异化）与Hotelling模型（水平差异化）有机结合，在假定顾客均匀分布的情况下，通过Hotelling模型进行市场划分，运用Nash均衡求得港口均衡定价策略。结果表明：港口的投资水平越高，港口吞吐能力越高，港口价格以及腹地市场都会增加，港口利润也会随之提升。
