The input-output connection analysis of industry structure based on complex network theory

In order to deeply reveal the structure characters of the real weighted complex networks, the clustering and correlation measures are given and compared from the view of topological and weighted network respectively. The structure of Chinese national economics in 2002 is set as an example to illustrate. The complex network model of national economic industry departments is established, the clustering and correlation characters of this industry relation network are analyzed by the software tool MATLAB with the data coming from the input-output data published by the national economic accounting department, therefore the input-output association structure characters of the national economic departments in our country are sufficiently explored.
