JUSTIFICATION OF A SYSTEMIC MODEL OF INTERSECTORAL LINKAGES IN THE ECONOMY

Abstract

The article is devoted to the development of a systemic model of intersectoral linkages in the economy based on intersectoral resource flows. The purpose of the study is to substantiate and develop a systemic model of intersectoral relationships that provides a holistic view of the structural dynamics of the economy, facilitates the identification of key leverage points for effective economic policy-making, and enables the adaptation of managerial decisions to contemporary transformational processes.

The paper examines the evolution of approaches to analyzing economic structure and substantiating a systemic model of intersectoral relationships within the framework of modern theoretical paradigms. A comparative analysis of classical, neoclassical, structuralist, new structural, and heterodox schools of economic thought is presented, which allowed the identification of key principles regarding the role of structure in economic development.

The study substantiates the need to transition to a comprehensive systemic perspective, where the economic structure is viewed as a dynamic network of interconnected sectors shaped by technological, institutional, social, and globalization factors. A systemic model of intersectoral linkages based on resource flows between the primary, secondary, tertiary, quaternary, and quinary sectors of the economy is proposed. It is found that structural transformation of the economy is accompanied by changes in the roles and significance of individual sectors, particularly the growing share of services and knowledge sectors in post-industrial societies.

The analysis of the role of institutions, technologies, production factors, and global influences revealed key drivers of structural change and their impact on socio-economic dynamics. The study concludes that the effective functioning of the economic system requires flexible management of intersectoral relationships, considering national comparative advantages, institutional capacity, and global economic dynamics. The presented model can be used for strategic planning, industrial policy formation, and forecasting long-term structural changes in the national economy.
