The article gives a detailed commentary on the theory of technological structures developed in line with the modern Russian economic school (first of all — by academician S. Yu. Glaziev and his associates), and an attempt is made to develop it in a number of methodological, theoretical-content and methodical aspects. In this target context, the authors, starting from the existing taxonomy of technological orders, firstly, touch upon not only the issue of identifying (measuring) structures, but also the problem of assessing the contribution of the latter to economic growth. Secondly, they propose an approach to solving the problem of assessing the influence of macroeconomic policy instruments on each of the structures identified by science, which has not yet been solved by domestic and foreign scientists. This means instrumentalizing the theory of technological structures and expanding the scope of its application. We are talking about the use of the considered theory not only in the structural analysis of economic growth and technological changes in the national economy, but also in the development of a strategy for the development of the national economy, in the selection of economic policy instruments. At the same time, it is proposed to put such selection on a solid basis for the application of precise methods. Several dozen regressions have been analyzed for the basic tools of macro-policy — with the rejection of factors and the choice of equations for the best statistics.
