Abstract: In the viewpoint of development, this paper has analysed the general trend in the evolution of transport structure, on the basis of which we have brought to light the internal factors of evolution about transport structure. It has also studied the rational criteria of transport structure under certain conditions.

Key words: transport structure, evolution trend, theoretical research
