Chinese Industry Association Studies Based On The Industrial Complex Networkanalysis Method

Industrial relationship is objectively exist in industry system,which used to describe the relationship between industries. Many problems of the economic system can attribute to the industrial problems, such as low level of industrial structure、primary industry system、single pillar industries、low industrial correlation degree、short industry chain problems. So, how to quantify the correlation between each industry? What will be the future industry correlation patterns? Whether or not the potential of emerging industries and key sectors received enough attention and support? In order to answer the above problem, this paper uses industry complex network method to analyze the industrial relationship.The research of industry relationship that began in the 1950 s has been around on the analysis of the input-output table. The research based on input-output model almost has become the general form of the industry association studies. Although this kind of research method can accurately quantify the intensity of industrial connection, the study of the classic method also has its disadvantages. For example, the traditional way to measure the correlation coefficient matrix between industries is tedious and discrete and not intuitive. Therefore, the researchers introduced the network model which has been developed into the industry complex network model later. However, there still exist some disputes and problems, such as: how many kinds of basic complex network we should establish? What is the base of coefficient matrix?In addition, the traditional approach to the problem of industrial connection gives less concern on the weights.This paper puts forward a more reasonable industrial complex network modeling method. Based on the total consumption coefficient matrix and total distribution coefficient matrix, two basic complex networks are established from the two dimensions. One is established from the perspective of the demand; the other is established from the angle of the supply. The modeling method can provide more effective application of input-output table data to reflect the actual situation of industrial correlation. In this paper, we joined the weighted complex network analysis on the basis of traditional network analysis. The combination of the two methods can not only analyze structural features but also to quantify the strength of the industrial connection degree.This article applies the improved method to describe characteristic of the Chinese industry association in 2010. Main conclusions are: the major power to promote the economic development of our country is coming from the construction and equipment manufacturing industry; And 16 different sectors of industry circulation system are formed around the two industries, there is strong interaction among 16 sectors. However, in the circulation system contains mostly energy supply industry and basic industries. Lacking of high-tech manufacturing and diversified production services illustrate the characteristic of our country industrial structure.In view of the weak links of the industrial structure, high-tech and innovative industry should be integrated into the circulation system of the whole industry to form a benign circulation industry development pattern. Priority to the development of the third industry which is highly concerted will stimulate the development of the whole economy.
