Abstract: The aggregation method is proposed for input-output statistical tables (intermediate consumption matrix and vectors of final consumption, production, gross domestic product (value added), overall costs) to reduce their dimension to be suitable for studies on medium-term and long-term forecast. The method does not impose constraints on a substantive nature of the tables and ensures their transformation without the loss of accuracy. When forming the aggregated mathematical input-output balance models, first of all, it is necessary to aggregate the intermediate consumption matrix in monetary form and after that transform it into the dimensionless matrix of direct costs through relevant valuation with subsequent well-known operations.
Keywords: matrix, vector, intermediate consumption, final consumption, gross domestic product, costs, production.
