Network structure of inter-industry flows

We study the structure of inter-industry relationships using networks of money flows between industries in 45 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. •Pedagogical intro to industry networks and national accounting to aid researchers.•Money flows between industries described by a Weibull distribution.•Sizes of industries described by an exponential distribution.•Community structure characterized by 5 major industrial sectors and sub-communities.•Results approximately invariant across different national economies.
