Abstract: The strategic choice and game equilibrium of vertical cooperation alliance between a High-Speed Rail (HSR) enterprise and two competing express companies were researched,and the influence of service level's difference on game equilibrium was analyzed.The research showed: the equilibrium state would be that all the two competing express companies form vertical alliances with HSR when the service level gap between two express companies was small;the equilibrium state would be that the express company with higher service level form vertical alliances with HSR when the service level gap was big,and the express company with lower service level did not cooperate with HSR.With the service gap increasing,the total revenue of these two equilibrium states was accelerated rose,and the revenue of express company with lower service level was slowed down.In the process of service level gap gradually increased from zero,the total revenue of the second equilibrium state exceeded the first state,and then the second state replaced the first state to achieve a new equilibrium.
