The theoretic methodological aspects were established and practical recommendations as to transformational reorganization of the economy of the agrarian sector of Ukraine were worked out in the doctoral thesis. The scientific views as to transformational reorganizations of economic systems were systemized that are based on systematic assimilation of economic systems theories fundamental postulates, and allow to consider transformational reorganizations on the cognitive (area of research), logic- epistemological (research categories and their interconnection) and methodological (methods and technologies of research results obtaining) levels. Economy transformational reorganizations architectonics was formed, and it was suggested to overview summary of transitive changes in its framework, which have cyclical pattern and occur in contrast to self-organization because of managerial influence that assist forming on the basis of identifying economy functioning problems in the conditions of its transfer from one qualitative stage to another.
The intention of the concept “agrarian sector” was researched, the subcomponents of transformational reorganizations were determined, the agrarian sector of economy transitive changes elements were established according to subcomponents of transformational reorganizations, the specifics understanding of transitive changes of land ownership and other objects of agrarian sector of economy transformational reorganizations.
There was methodology of process research of agrarian sector of economy transformational reorganizations formed, that is represented as integral complicated subordinated system of scientific – prescriptive, conceptual-descriptive and procedural-praxeological components that allows to deepen its research of agrarian sector of economy transformational reorganizations, which is in theoretical development of provisions that reveal concept and content of this process, its regularities determination, widening and considering transformational reorganizations estimation system (quantitative and qualitative estimate. There were proposed and visualized elements of scientific prescriptive, conceptual descriptive and procedural-praxeological components of methodology of transformational reorganizations research.
There was contribution of the agrarian sector to the functioning of the national economy of Ukraine established, there were also transformational reorganizations by stages of transitive changes of agrarian sector economy abstracted, a model of dependence of gross output of agrarian sector on production factors was constructed, which in comparison with existing was built by using modified productive function and allows to analyze and formalize results of agrarian sector functioning.
The priority directions of governmental regulation of agrarian sector of economy were determined that in contrast to existing ones were divided into organizational legislative, productional technological, financial technological, financial economical spheres and sphere of foreign economic relations state influence on the economy of the agrarian sector, the realization of them will allow in future to ensure the effectiveness of transformational reorganizations of agrarian sector economy. The approach to gross output product of agrarian sector of Ukraine was also improved. A graduality of agrarian sector economy adaptation to transformational reorganizations was worked out that in the contrast to others consists of stages of bifurcation-parametric, structural-functional and modulation adaptation that foresees the completion of corresponding adaptative procedures that ensure the proper direction of each stage of adaptation of the economy of the agrarian sector to the necessary results of their implementation.
There was a mechanism of agrarian sector economy transitive changes management created, which in comparison with existing ones consists of four management levels that include goals management, production factors management, risk management and effectiveness management, their practical realization will allow to finish the adaptation process of agrarian sector economy to transformational reorganizations and ensure its effective functioning in modern conditions.
