Abstract: By calculating the information entropy for the scale of construction of energy transportation corridor with the data of annual investment in the fixed assets from 1986 to 2008,the authors analyzed the relation between transportation channel and the information entropy combined with the maximum entropy methods.Empirical results show that the rail transportation investment should remain the current growth,while the road investment should be reduced,and the waterway and pipeline transportation should be constructed.The quantitative evaluation of the construction scale of energy transportation channels is an important supplement to the traditional research and provides evidence for further development.

Key words: energy transportation channel, information entropy, investment in the fixed assets, construction emphasis, structure improvement
