The purpose of the article is to justify rational approaches to improving the organizational and economic mechanism for the provision of agricultural protection with technical means, to highlight and describe organizational and economic components of the aforementioned mechanism, to systematize principles of its implementation, to identify the most effective and productive methods, leverages and instruments of influence, to approach formation of an environment and favourable conditions for an interaction between subjects and objects within the framework for implementation of optimal models of technical provision. Research methods. In the research process the following methods were used: dialectical method of cognition, which made it possible to study the process of providing agriculture with technical means, taking into account causal relationships with key market and production factors; systematic approach for achieving an optimal composition, structure and principles for functioning of the organizational and economic mechanism of the provision of agriculture with technical means; retrospective analysis, which allowed to assess dynamics of the state and provision of agriculture with technological means, determine changes in an efficiency of their use and compare with average indicators of such efficiency in the economy in general; statistical analysis, namely rows of dynamics, average and relative values, index, comparison, etc. Research results. The current state and trends of technical provision of agriculture were analysed. Imbalance of technical means and performance in the economy and agriculture was found, and changes in the level of return on money used in the formation of basic means of agriculture and the economy in general were estimated. The necessity of optimization of principles of technical provision of agriculture on basis of the formation and implementation of a complex and effective approach was proved. Improvement principles for the organizational and economic mechanism of provision of agriculture with technical means were substantiated. Principles, methods, leverages and instruments of the aforementioned mechanism were systematized, as well as its institutes and institutions were allocated. Particular attention was paid to the formation and interaction of organizational and economic components of the mechanism, ensuring their positive influence on the formation of environment and conditions for interaction between entities and objects of technical support, and optimization of supply models of technical means in agriculture. It was shown that a complex of developed proposals will increase a level of technical support of agriculture in Ukraine, and as a result, it will positively affect the industry’s development, volumes and quality of agricultural production, food security of the state, its export potential and role in the world agrarian markets. Elements of scientific novelty. Scientific and methodical approach to the improvement of an organizational and economic mechanism for providing agriculture with technical means is based on the formation and implementation of special methods, leverages and instruments of influence on processes of production, supply, acquisition and use of agricultural machinery, enhancing interaction of institutes and institutions, taking into account rational principles for work, creation of favourable interaction conditions and environment for functioning of subjects and objects of the technical supply. There were identified economic and organizational components of the mechanism, and its elements, including legal and monitoring-informational support, logistics, consulting, coordination, motivation, coordination of parties’ interests, formation of financial flows, were systematized. Practical significance. Organizational and economic mechanism of providing agriculture with technical means was offered. This gives an opportunity to form an optimal environment for the interaction of subjects and objects of technical means’ supply, and to create attractive conditions for their interaction on basic of introduction of direct, leasing or hybrid model of the technology use. Ultimately, practical implementation of the proposed organizational and economic mechanism will help to improve a technical and innovative level of agricultural producers and increase their efficiency.
