Research Of Transport Structure Based On Information Entropy And Gry Relevance

Nowadays> transportation occupies a pivotal position in the economy, the impact of various factors of transport structure with the rapid economic development, hi general, the qualitative analysis of transport structure is the lack of quantitative analysis. In this paper, the use of information entropy and gray relational theory analysis of the transport structure, illustrate the balanced of the transport structure and mode of transport related degree.First of all, this article is to introduce the basic definitions and the basic characteristics of the transport structure, specifically on the advantages and disadvantages of Each Transport Mode in the transport structure, at the same time in-depth introduction to the structure type and influencing factors.Secondly, the specific study of definitions and properties of the information entropy analysis method of gray correlation model building, using entropy theory analysis of transportation structure mode of transport information entropy, a balanced transportation structure and dominance indicators, the size of the information entropy can reflect the difference degree between the transport structure, have a certain relationship to the number of mode of transport and high and low of entropy, balanced the greater the degree that the mode of transport more balanced. Meanwhile, in the transport structure, using the concept of complexity building transport structure metric model.Finally, Inner Mongolia Transport data to analyze an example, the use of information entropy and gray correlation analysis and calculation, study the different of economic and social indicators for the mode of transport have the degree of association, at the same time, at the same time, through the comparative analysis of the Inner Mongolia transportation structure and transport structure, obtained the strengths and weaknesses of Transportation in Inner Mongolia.
