Network analysis of the US industries interconnection

Abstract

In this paper, we publish the results of a study of the US economy interconnections, using network analysis. The study is based on modern and classic scientific papers on cross-sectoral and network economic analysis, as well as on the official statistics published in the USA. The purpose of the study is to identify those industries where economic shocks will have the greatest impact on the entire US economic system. The work is equipped with the necessary general theoretical information and a description of the research methodology. In the course of the study, were analyzed different in composition and number groups of sectors of the US economy and were constructed the graphs reflecting the structure of the industries network interaction in each of the considered groups. There is also made the calculations of various numerical values of the centrality of networks for each of the studied groups of US industries. For each of the numerical values of centrality of the used network are given the necessary explanations. The study shows the industry leaders for each of the calculated centrality values of the network for each of the studied groups of the US industries for which calculations were carried out. The obtained results were evaluated and interpreted to the required extent. In addition, the obtained data of the values of the centrality of economic networks were compared with indicators of real value added by sectors of the economy. During the study and in its results, a number of different conclusions were formulated, which are also sequentially presented in the text of this publication, including all the necessary comments and explanations. In particular, it has been shown that the most “central” sector of the US economy is “transportation and warehousing”.
