Abstract

This article introduces the input-output table as a tool for representing the interdependence of branches and sectors within a national economy. It explains the logic and structure of the table, the meaning of its main components, and the relationships linking production, intermediate consumption, value added, and final uses. The paper also shows how aggregated national accounting variables can be derived from an input-output framework at market prices. By combining conceptual explanation with simplified numerical examples, the article highlights the table’s usefulness for economic analysis and planning.
