摘要
为使集装箱班轮运输公司在寡头垄断市场结构下实现利润最大化,运用古诺模型和伯特兰模型进行班轮定价.根据古诺模型,班轮公司通过确定运量来实现利润最大化;试图通过降价来增加利润,导致运价最终趋向伯特兰均衡点.引入运能限制后,不存在伯特兰均衡运价;引入理性预期后,运价趋向于古诺均衡运价.运用优化后的模型分析,得出封存运力、联合经营和提价计划能够有效稳定和提高市场运价的结论.
In order to realize the maximum profit for container liner transportation companies on the oligopoly structure market,the Cournot and Bertrand model are used for liner transportation pricing.According to the Cournot model,container liner transportation companies maximize profits by determining volume;however,they always try to increase returns by price-cut,which leads to the price dropping to Bertrand equilibrium point at last.There is no equilibrium price when volume restriction is considered,and the price rises to Cournot equilibrium point when container liner transportation companies are rational.The conclusion from the analysis of the optimized model is that the sealing up transportation,joint operation and carrying out the price hike plan can stabilize and improve the market transportation price effectively.
