Network structure of inter-industry flows

Published 18 Apr 2012 in physics.soc-ph, cs.SI, and q-fin.GN | (1204.4122v1)

Abstract: We study the structure of inter-industry relationships using networks of money flows between industries in 20 national economies. We find these networks vary around a typical structure characterized by a Weibull link weight distribution, exponential industry size distribution, and a common community structure. The community structure is hierarchical, with the top level of the hierarchy comprising five industry communities: food industries, chemical industries, manufacturing industries, service industries, and extraction industries.
