在改进的Hotelling模型基础上,构建了多个港口企业合作情况下的定价模型,比较了在竞争与合作情况下多个港口企业的市场份额与利润的关系.结果表明:当港口企业的服务水平相当时,港口企业在合作前后的市场份额和利润变化取决于其位置;而当服务水平不同时,在合作与不合作的条件下,港口企业总市场份额和利润与港口位置及服务水平有关.
Based on modified Hotelling model,this paper built the pricing model of port enterprises under cooperation condition,compared the demand and profits of port enterprises under competition and cooperation condition.The studies indicate that when the service levels are the same,the total demand and profits of the adjacent port enterprises are affected by their locations,when the service levels are not the same,they are influenced by the locations and service levels.
