The Analysis Of River-port's Competition And Cooperation Based On The Hotelling Model

The inland river transportation of China originated in the 1870 s. After the China's reform and opening-up policy launched, thanks to the rapid expansion of economic, the inland river transportation comes to a rapid development. In recent ten years, rely on the natural advantage, the inland river transportation attract more and more attention from the government and researcher. China has formed six inland river transportation system which involved the Pearl River, Huaihe River, Heilongjiang, Songhuajiang, Grand Canal and Yangtze River. As the connection of water-land transportation, the inland river port faces a higher require of its operation management.This thesis takes the forwarder's behavior into account, analyzing the service charge decision under the competition and co-optetition between two ports and multi-ports by building a mathematical model. And further analyze the port operator's preference about the way used to make the service charge and the relationship between the port's location and the port service charge and market share's variation. The result shows that when there are two ports competing, with the different relationship about the transportation's marginal cost and port's location, the port locates in the upstream would prefer different service charging way. But the downstream port would not change its preference no matter how the transportation condition changed. When there are multi-ports competing, the port's charge would be higher with the location moving to upstream. At the same time, the market share would be also changed regularity. At last, the conclusions which concluded from this thesis are tested by the Yangtze river ports.
