The Interregional Structure of the U.S. Economy

Abstract

Regional input-output models demonstrate that state economies in the United States have strong interdependence of final demands, income payments, and intermediate product, but there are no explicit, spatially detailed estimates of the structure of this interdependence. Building on survey data which document the spatial structure of interregional trade for a sample of Washington State firms, this paper develops a 51-region model of the U.S. economy for the year 1980. Characteristics of the interindustry structure of this model are described, and probable qualities of its evolution are discussed.
