The content of the concept of sustainable economic development has been improved, which is proposed to mean the change of the vector of economic development on the basis of paradigmatic changes in the philosophy of management, the essential content of which is the transformation of the principle of rationality, supplementing it with non-economic (social and environmental) components as a basis for the formation of a motivational mechanism of action of economic entities, as well as the management subsystem at the micro, macro and supranational levels. The core of sustainable development is determined. It is proved that the essential connections between the elements of the structure of sustainable economic development are determined by three laws of institutional architecture: the law of equilibrium, the law of averaging (golden mean), the law of structuring (golden section). It is established that the construction of the economy according to the law of the golden section gives it the greatest dynamism with the most economical mode of operation. The key trends of structural transformations of the global economic system are identified. It is proved that the current structure of the post-industrial economy does not meet the principles of sustainable development. The necessary conditions for the implementation of the paradigm of sustainable development in the economy of Ukraine are highlighted, realized in reforming the institutional matrix by providing these conceptual changes: formation of effective institutions for the specification of property rights, reducing the share of extractive institutions by breaking the mechanism of formation of rent motivation, increasing the efficiency of transplantation of institutions on the basis of blocking their dysfunctions, effective realization of the state's potential in ensuring the balance of interests of economic entities.
The network of basic (most significant) concepts that define the essence of the category "adaptation" is identified using the software product TextAnalyst. The importance of adaptation in the socio-economic environment is specified as a process of readjustment the internal properties of the enterprise to the requirements of a dynamic environment based on the use of organizational, economic and social regulators in order to ensure sustainable operation in the long run. It is proved that the internal system of the adaptation mechanism is structured by the selection of such elements as: adaptive potential, adaptive capabilities, external forces, elements of adaptation, adaptation vector, adaptation process, bifurcation points, attractors. The role of human capital in ensuring sustainable economic development of agro-industrial production is determined. The methodological bases of identification of object spheres of adaptive mechanisms application of management of agro-industrial development are substantiated, which are based on decomposition of object of management.
An assessment of the state and dynamics of agricultural production in Ukraine is carried out: macroeconomic indicators, indicators of the dynamics of Ukraine's foreign trade in agricultural products. The factor of potential danger of dependence of national exports on a limited number of commodity items of raw materials (cereals, corn, oilseeds) is highlighted. The regions are grouped according to two indicators: growth dynamics and share in the total volume of agro-industrial production, their qualitative characteristics are given. It is determined that the development of the agro-industrial sector within the strategy of predominance of extensive factors, the dominance of economic determinants of functioning was reflected in the neglect of environmental parameters, which shows the lag of the integrated environmental block from the national level in 2019 more than 2 times. A model for estimating the level of sustainability of economic development has been developed, which combines 4 aspects of evaluation: economic, social, environmental and infrastructural blocks, the values of which are calculated by many quantitative factors in relation to the national economy in general and agro-industrial complex in particular.
