Based on the dynamic game theory and the Leontief model, the event of west coast port
lockout in USA is analyzed by applying the Nash equilibrium model, and its possible results are
discussed. The research shows that after the struggle between the Stock Workers Union (SWU)
and the Pacific Maritime Association (PMA), the Pareto optimality can be approached in a long
period. However, with the change of environment and time, this equilibrium will change, and the
struggle between the SWU and the PMA may arise repeatedly. Therefore, this kind of events will
emerge in the future again.
