The developed model of the economic system technological core uses the intersectoral balance of the national accounts of the economy. The analysis of the model consists in determining the preferred structure of releases at the stages of development of the technological core of the economic system. The mode of controlled economy involves the use of a strategic planning methodology. We showed that with the use of strategic indicative planning methods, the productivity of the Russian economy could significantly increase yet at the first stages of the plan. Proposed methodology of indicative plan formation is mathematically justified. Numerical examples of its implementation with the real statistic data are given. The results obtained indicate the prospects for the development of centralized planning institutions for the development of the technological infrastructure of the Russian economy. These institutions are especially relevant in a situation of unprecedented external sanctions.
