Abstract: Based on the characteristics of cross-border logistics alliance and operational risk control of the system, and by analyzing the operation process of cross-border logistics alliance, the paper identifies its operational risk and establishes an operational risk index system. From the perspective of the game behavior of enterprise selection strategy in the cross-border logistics alliance, it analyzes the decision-making behavior of the enterprises within the alliance by means of game analysis, establishes an evolutionary game model under the internal penalty mechanism of the alliance, and simulates the evolutionary stability path of the cross-border logistics alliance with system dynamics to study the changes in the selection strategy of the alliance within the alliance when operating factors affect the operation of the alliance. Research shows that in order to effectively evade the operational risk of the alliance, a scientific punishment mechanism needs to be established to prevent speculation within the alliance.

Key words: cross-border logistics alliance, evolutionary game, system dynamics, operational risk
