The Networks of Inter-Industry Flows in a Sam Framework

The networks of nominal flows between industries in a Social Accounting Matrix (SAM) framework are studied. The flows of the SAM submatrices of production (or output of goods and services) and intermediate consumption, are identified, which are constructed from the supply and use tables of the National Accounts. From these flows, the inter-industry networks are induced. The structure of these networks are analysed, as well as, the underlying generation of income.An application to Portugal illustrates the approach
