基于Bertrand模型的区域港口双寡头定价策略

Duopoly Pricing Strategy for Regional Ports Based on Bertrand Model

基于Bertrand模型的数理分析研究了区域港口双寡头的最优定价策略,指出双寡头在定价策略上的合作有利于提高双方的价格和利润。当寡头存在强弱之分时,强势的寡头定价高一些,弱势的寡头定价低一些,在双方价格的纳什均衡点,双方可以获得最大化的均衡利润。并以上海港与宁波-舟山港为案例进行了实证分析。

The paper analyzes mathematically the optimal pricing strategy for regional ports with duopoly. It is found that, cooperation within the duopoly on pricing strategy can help improve the price and profit for both parties and when there exists discrepancy between the strength of the two, the stronger one will land a higher price than the other and both can realize maximum profits when their prices reach Nash equilibrium. At the end, an empirical study is conducted in the cases of Shanghai Port and Ningbo-Zhoushan Port.
