Intersectorial Structure of National Economy: Algorithm for Studying Industrialization Rate

The sectoral structural theory of national economy by Clark-Fisher is based on the hypothesis that a gradual redistribution of production of the highest GVA value from the agrarian to the industrial sectors and then to the service sector occurs in the course of social evolution. The authors of the paper present their achievements in studying industrialization and servicing rates of economy while taking into account, firstly, the tendency of non-material services and manufacturing industries increase in the regional economic intersectoral structure; secondly, the need to develop methodological basis for analyzing intersectoral structure of economies of any scale. We applied new typology which allows not only to evaluate and compare the achieved level of economic development of a particular territory, but also to underline priorities of economic policy in digitalization, industrial revolution and introduction of “industrial Internet” into public strategic regulations. The principal conclusions drawn by the authors of the paper are the following one: national economy can be presented as a superposition of various types of mesoeconomies at the appropriate levels of its decomposition; each mesoeconomic type can be quantitatively characterized by the degree of evolutionary development of the intersectoral structure and its developmental vector in the area of indicators of industrialization and service economy development rates at each level of the hierarchy of
