Research On Interaction Among The Three Industries Based On Complex Network Theory

The development of global economy appears a new indication that is the service industry has playing a more and more important role in various countries and the coordinated development of the industrial structure had became more and more apparent since the latter half of the 20th Century. China's"Eleventh Five-year Plan" has put forward to develop modern service industry, in order to change the economic development mode from manufacturing-led to service-led. So what is the status of the three major industries? What is the relationship between these three industries? These issues need us to study further.This thesis summed up a wide range of study literatures at home and abroad to gain valuable research results. Then, we use the input-output method and DEMATEL method which combining the statistical with comparative analysis methods, and quantitative with qualitative analysis methods to research on the correlative effect among industries and the industry structure. In this thesis, there have been some results through the use of comparative analysis and input-output analysis. The conclusion is as follows:(1) We organized the literature and theory used in this article and make a more detailed review of the literature; (2) Using input-output theory to analysis the inter-industry relationships and interrelated impact on national economy of United States and China; (3) Using complex network theory to analyze the interrelated relationship of U.S. industry between 1998 to 2007 and the relationship between the 65 departments; so as to China; (4) We compared the conclusions from these two methods, meanwhile, in order to promote the optimization and upgrading of industrial structure in China, this thesis given a certain amount of policy suggestions.
