Abstract:

In order to study the impact of port differentiation strategy proposing in network nodes, a port pricing bi-level optimization game model is built based on the multinomial Logit (MNL) model and game theory, and a numerical algorithm is developed to solve the Nash equilibrium. With a numerical example, the market share change, optimal pricing and service routing strategies as well as the influence of user preference factor on equilibrium price are studied. The results indicate that: the new service promotes the freedom of company strategies and profit level; the pure pricing strategy has a limit to earn the market competiveness, and it’s more passive in the market. In this example, it is pointed that when users are more interested in the price factor, the pricing strategies is more effective. However, pricing strategy has limited range. Company cannot fully dominants the market by pure pricing strategy while with new service, company can gain the advantage from the competition and make a higher profit.
