The purpose of this study is formation of tools for forecasting the economic security of the enterprise by modeling methods when changing investment support. The relevance of this study is due to the need to solve the problem of modernization management system of the enterprise by implementing the project management of economic security of the enterprise in the implementation of investment programs.The variant of model offered economic security of the enterprise. This model involves the implementation of the process of adaptive management, based on the definition of safe limits of longterm growth of the enterprise. It has established that the ratio of self-organization processes and managerial influences depends on the value of the self-organization coefficient. The calculated value of adaptive potential on the basis of the indicator of self-organization as the dynamic indicator of maintenance of perspective growth of the enterprise on the allocated purposes has offered. This indicator can serve as a criterion for assessing the effectiveness of the management system of the enterprise in relation to the project management of economic security of the enterprise in the implementation of investment programs of key goals of long-term growth of the enterprise.

The purpose of this article is to analyse the main factors of innovative development of the agrarian sector, to run a research on investment support of innovations, which will enable to determine the main directions of improvement of the mechanism of state regulation of investment in the innovative development of the agrarian sector of the country. The methodology of the research is to substantiate the necessity of state support of innovative development of the agrarian sector, as a priority direction of its investment support, which involves the implementation of a set of measures to change existing trends, reducing the amount of financing of scientific and technical works, and reducing the number of research institutions involved in the development and implementation of innovative products in agriculture, while creating an institutional environment for development and implementation of agrarian innovations through the national and regional investment funds, promotion of the implementation of scientific developments into production by expanding the availability of financial resources through public and private partnerships and the commercialization of research results. The results of the study indicate that Ukraine's agriculture has potential opportunities to improve its competitive advantage in world markets. However, in order to strengthen them, it is necessary to take a number of measures: to form economic and political support for agricultural enterprises using scientific equipment and new technologies; to ensure the creation and distribution of a network of innovative funds to support innovative business at different levels; to orient all loans and support in Ukraine to implement innovative projects in specific areas of production development, including innovation and investment support of agricultural enterprises; Provide additional tax incentives for enterprises producing innovative products, which will increase the financial resources for the implementation of innovation projects and innovation program; clearly identify the legislative provision of funding and form a mechanism to support small businesses. Practical meaning. The identified development priorities can serve as a basis for creating conditions for the domestic agricultural enterprises to implement the offensive strategy in foreign markets, supporting constructive competition in the domestic market, which will stimulate agrarian formation to innovation, ensure close integration of production and science, in order to facilitate the advance development of scientific and technological sphere. Value/Originality. The results of the study indicate that improving the investment provision of the agrarian sector of the economy involves determining the prospects for its long-term development based on scientifically based methodological approaches, the use of which allows measuring changes and expected socioeconomic outcomes.

Abstract. The article highlights the relevance of the modernization of production and economic activity of enterprises and farms of the agricultural sector in the context of institutional transformations. The analysis of modernization studies by fundamental and applied economic science is carried out, the problem statement is made.The results of researches of agrarian economic science on the main directions of modernization of production and economic activity of agricultural enterprises and farms are given. The generalization about belonging of modernization to economic categories has been made, which reflects the general properties of real reality and serves as a natural mechanism of its upward development due to the improvement of the man of production and economic activity, provides economic progress and improvement of the level and quality of life of the population. Institutional changes have been identified, as evidenced by an overall increase in the number of agricultural enterprises, a decrease in farms and annual fluctuations in the number of agricultural entities. It is established that in agriculture, agricultural enterprises and farms are focused on the production of grain and legumes, sunflower and sugar beet, while households are mainly engaged in growing potatoes, vegetables, fruits and berries. In animal husbandry, agricultural enterprises have a certain advantage in the production of meat (in slaughter weight) and eggs, and households dominate dairy cattle, sheep and beekeeping.The importance of each category of farms in the agrarian sector of the economy in the production of basic agricultural products is determined. The arguments about the need for modernization of production and economic activity of agricultural enterprises and farms are presented.The complex of measures of modernization of production and economic activity of the studied subjects is substantiated, economic individualization of which is combined with processes of cooperation and agro-industrial integration in clusters of integrated territorial communities of rural areas. Keywords: modernization, production and economic activity, enterprise, farm, institutional transformations. JEL Classification Q12, Q14,Q18 Formulas: 0; fig.: 0; tabl.:2; bibl.: 12.

In the article the authors’ interpretation of the "economic engineering" construct in the context of the theory and practice of enterprise strategic management effective system organizing in modern conditions is formulated and substantiated. The idea of using “economic engineering” as a logistics (logistic tool) for constructing an enterprise strategy by generating and presenting possible alternatives for key business aspects of its functioning and development and selecting among them the best options based on their risk assessment is proposed. In order to present and realize the logistics capabilities of a multidimensional morphological matrix in the framework of “economic engineering”, it is proposed to use a framework model of justification and choice of optimal solutions based on their risk assessment, which underpins the idea of frame representation and organization of logistic interconnections.

Introduction. Attention to grain production is driven by its strategic importance within Ukraine's agro-industrial complex, as its products are critically important as key foodstuffs to support the life. The purpose of the article is to substantiate the economic efficiency increase of grain production in agricultural enterprises in the Mykolaiv region in modern conditions. Results. The general characteristic of the Mykolaiv region agriculture is given. The essence of the concept of «economic efficiency» is revealed and the indicators of its measurement for food grain are proposed. Indicators yield grain crops to the dynamics are considered, outlining the growth of spring wheat, but the reduction millet and buckwheat. The economic efficiency analysis of grain production in agrarian enterprises of the Mykolaiv region has been done for the studied period by the following indicators: yield, cost of 1 centner of production, average selling price, profit, profitability. As a result of the combined impact of rising cost and price, profitability declined by 8% to 25.7% in 2017. The role of scientifically grounded structure of acreage is considered in ensuring efficiency of agricultural enterprises management based on crop rotation of different soil and climatic zones of Ukraine as a form of organization of their alternation in cultivation. Construction parameters for economic and mathematical model of acreage areas optimization of grain crops in agrarian enterprises of Mykolayiv region are presented. Conclusions. As a result of the proposed model calculation, optimized values of the specific gravity of the acreage under different crops have been obtained: the sowing of spring wheat will increase by 10% and the smallest – peas by 2%. It is proposed to reduce the acreage under winter wheat by 14% and spring barley by 8%. Such changes will have a positive impact on sales revenue, product cost, and overall profitability. Keywords: agrarian enterprise, grain crops, economic efficiency, intensification of grain production, yield, cost, profit, level of profitability, economic and mathematical model.
