A path analysis model of the influence factors is established in the collecting and dispatching system in the container ports.A case study is made of 10 major largescale container terminals in the world,and an analysis is made of the ways and extent of the factors’ impacts on the volume for different transportation modes.Results show that developing railway ports is a major way to release the pressure on road and the key to improve railway ports is to build special railway container loading and unloading stations for ports.The competition between railway and inland river is proposed to be avoided.Free port policy is recommanded for improving the volume of the feeder lines.
