Abstract:The purpose of this study is to establish a model of transshipment port competition in order to understand container carriers’ transshipment port selection. Accompanied by the enlargement of containership, the hub-and-spoke network is developed due to the economic consideration of containership routes. In between the feeder port and hub port, the production and attraction relationship can be existed. For pursing the maximum benefit, the carriers will choose the better hub port for their container transshipment base. Based on this assumption the authors established the “Port Container Transshipment Competition Model (PTC Model)” to conduct the empirical study on Taiwan international ports which coincides with observed data.
