将港口服务产品的网络外部性和服务质量水平引入到发货人的效用函数中,通过Hotelling价格竞争模型分析港口FDI企业与内资港口企业的博弈策略行为,分别研究在Nash和Stackelberg博弈条件下,港口服务价格、收益与网络外部性系数、服务质量水平之间的关系.理论研究的结论表明:港口FDI企业与内资港口企业在Stackelberg条件下的最优定价、均衡收益均大于Nash条件下的最优定价、均衡收益;企业最优定价随网络外部性强度线性递减,随服务水平线性递增;企业均衡收益受服务水平和网络外部性强度的影响,呈现出一定的区间变化规律,处于相同港口外部市场环境下,内资港口企业与港口FDI企业的服务策略选择和侧重点不相同.
This paper introduces the network externalities and service quality of port service products into the utility function of the shipper. By analyzing the Hotelling price competition model, this paper analyzes the game tactics of port enterprises in the port and domestic port enterprises, and studies the game strategy under the conditions of Nash and Stackelberg games respectively. The relationship between port service price, income and network externality coefficient, service quality level.The conclusion of theoretical research shows that the optimal pricing and equilibrium return under the Stackelberg condition between port FDI enterprises and domestic port enterprises are all greater than those under Nash conditions The optimal pricing of the firm decreases linearly with the intensity of the network externalities and increases linearly with the level of the service; the equilibrium income of the firm shows a certain range-change rule under the influence of service level and network externalities, which is outside the same port Under the market environment, the service strategy choice and emphasis of domestic port enterprises and port FDI enterprises are different.
