The dissertation presents a new solution to the scientific problem of improving the economic mechanism for the development of investment activity of agrarian enterprises by substantiating theoretical and methodological principles and providing practical recommendations for the formation and implementation of a conceptual model of the economic mechanism for the development of investment activity of an agrarian enterprise, which should be based on the economic mechanism of management and strategic principles functioning as key; system-reproduction approach, since investment activity has a complex nature and is constantly reproduced, on the one hand, on the other - it acts as a basis for reproduction; "lean production" technologies, which includes optimization of the process of management (enterprise, finance, production, etc.) and production taking into account customer orientation; should contribute to ensuring sustainable growth, expanded agricultural production and development of agriculture based on the innovation-investment type of expanded reproduction. The list of basic principles on which the improvement of the economic mechanism for the development of investment activity in agriculture should be carried out has been improved: the construction of an economic mechanism on a single methodological basis, with the aim of eliminating contradictions and disparities in the system of economic regulation of investment activity in the field of agricultural activity; the priority of the price as the core of the economic mechanism and the main regulator of the market economy in the process of economic regulation of the development of the investment activity of the agricultural enterprise; the functioning of each economic lever within the limits of its purpose and their performance of only their immanent functions, which reflect their role in stimulating and ensuring expanded reproduction in the field of agriculture; ensuring close interaction of individual economic regulators (prices, taxes, credit) in the process of economic regulation of investment activities with the aim of ensuring a synergistic effect from their functioning. The content of a number of basic concepts of the economic mechanism of the development of investment activities of agrarian enterprises was analyzed, in particular: "investment activity of an agro-industrial enterprise" means a system of coordinated actions and processes of a managerial, organizational, economic, regulatory and other nature in relation to targeted search, attraction, investment of funds and other resources in various forms to ensure the effective operation of the agro-industrial enterprise and each of its functioning processes, the achievement of economic, production, social and other goals and effects; under the concept of "economic mechanism for the development of investment activities of agrarian enterprises" it is proposed to consider a system based on the economic interests of various subjects in the process of finding and attracting funds and other resources, with the aim of their further use in the production process of an agro-industrial enterprise in order to ensure its effective operation in general and each of the processes of its functioning, achievement of economic, production, social and other goals, effect. An improved comprehensive system for evaluating the effectiveness of the economic mechanism for the development of the investment activity of an agricultural enterprise is proposed, which should be carried out on the basis of the calculation of an integral indicator, which is calculated using the indicators we developed, distributed by subsystems of the activity of an agricultural enterprise (production, financial, or organizational-management) with further determination of the level of efficiency according to the scale of identification of the level of the complex indicator of the efficiency of the economic mechanism of the development of the investment activity of the agrarian enterprise. Recommendations regarding the improvement of the economic mechanism for the development of investment activities of agrarian enterprises at the macroeconomic and microeconomic levels of the state economy have been formulated and substantiated.
