The Scale Structure Equilibrium Of Container Ports Network Based On The Strategy Rationality Model

In the paper, the appearing hub-spoke network model of container ports and its market foundation are analyzed on the basis of the developing trend of container transportation industry. Adopting the two-stage Cournot model, the scale game equilibrium of container ports is studied and its subgame-perfect pure strategy outcome, i.e. the scale structure equilibrium of container ports network, is obtained found on the market competition condition, then the scale concentration mechanism is proved. The Chinese container ports network is studied and its scale structure is analyzed in the illustration.Considering the market condition and utilizing strict economics theory, the equilibrium is obtained, which is helpful to macro control and market decision. As for the government, whether a policy can promote and maintain the market equilibrium testify the policy is good or not. Industry administrators should abide this principle when make, enforce, evaluate and amend a market policy.For restraining ports from abusing their exclusive position, an organization that constituted of central and local government together should be established to control and supervise the container ports market. The organization supervises the actions of every individual executive and controls the market directly or indirectly, then makes up the market structure defects, avoids excessive scale concentration and ports positions abusing, prevents wasting resulted from resource allocation improperly during the economy structure regulation.
