Abstract: This scientific article studies the problems of mathematical modeling of the interdependence of economic sectors across the country. The relevance of the article is that if the state plans to increase the volume of final products in one sector (for example, industry), it is impossible to calculate how much additional costs this will require in other adjacent sectors (energy, transport, agriculture) without accurate mathematical matrices. To solve the problem, V. Leontiev's "Cost - Production" inter-sectoral balance model was used. In the practical part, direct costs and Leontiev's full cost matrix were calculated on the example of a two-sector conditional economy. The results of the study show that the state's target programs for economic growth can achieve a real balance only if they are based on gross production volumes obtained using inverse matrices.
