THEORETICAL PRINCIPLES OF MANAGING ECONOMIC SYSTEMS IN OPENNESS

The article deals with issues related to the management of economic systems. When building a new methodology for managing economic systems that takes into account national interests and priorities of economic security in an open environment, it should be borne in mind that recent processes at both global and national levels (rapid economic and technological development, the emergence of economic innovation, social and economic networks) can no longer be explained within the existing theoretical economics, based on the following postulates adopted in order to simplify the picture and its greater analytical feasibility. Issues of management of economic systems in an open environment are relevant in any sector of the economy. Previously formed economic theories were unable to ensure early detection, justification of the preconditions for the development of recent large-scale defaults in the world economic system, financial crises. Which is primarily due to the fact that the substantive axiomatics of economic theories do not reflect the socio-economic reality and in an increasingly complex economy, can no longer act as an integrative paradigm of development. The practice of economic development and financial markets, synergetic and systems analysis reveal many serious shortcomings and contradictions in the basic assumptions that currently prevail in economic theories. As a result, real people's behavior is often irrational, real-world market systems lack the harmonious completeness inherent in theoretical models, and are inefficient. assets and do not fully meet current needs, providing an instant supply of the asset; crises and market failures are so rare and can only be exogenous in nature and not induce negative dynamics within. In order to successfully implement this system on a national scale, it must be approved in the form of an appropriate top-level economic security strategy of Ukraine and a tactical program of action aimed at strengthening the existing and future advantages of the Ukrainian economy to maintain national competitiveness and self-sufficiency of the Ukrainian economic system.
