Abstract: Based on the mode of "high-speed rail network + express network", in order to study the influence of dominant power on the price strategy of high-speed rail express supply chain, the Stackelberg game models of centralized decision-making, China Railway Express dominant, traditional express enterprise dominant and Nash equilibrium are respectively established, and the optimal price and maximum profit under four models obtained. The research shows that the optimal direct selling price remains the same under different dominant structures, while the optimal retail price is the highest when it’s decentralized. The wholesale price is controlled by the dominant enterprise. Decentralization will lead to the loss of the overall profit. The dominant power is conducive to the leading enterprise to obtain much profit.

Key words: high-speed rail express, dominant structure, price strategy, service level, Stackelberg game
