The article develops theoretical and methodological foundations for the formation of the concept of food security management of the state in terms of investment and innovation development of the agricultural sector. It is determined that the essence of food security is the economic state of the country, in which, regardless of market conditions, the population can be guaranteed and stably provided with food resources, have free access to them in sufficient quantities, range and at reasonable prices, with this corresponds to the normatively justified parameters and medical standards. It is established that the concept of economic security of the state involves the effective functioning of all its constituent subsystems, which must ensure efficient and rational use of all relevant resources to eliminate possible external and internal threats, ensure the stability of the national economy and direct protection of state interests. Stimulating the development of agricultural production and reducing the negative impact of its systemic indicators will ensure the stability of food security and food independence by increasing the sustainability of agricultural production and food quality and income, expanding exports and imports, increasing food stocks, improving greening, improving the legal framework, realization of production potential of agriculture. The paper notes that food security is one of the most important indicators of socio-economic development of the country. It is provided primarily by the level of agricultural production, saturation of the market with its own agricultural products, which promotes its independence and meets the main groups of indicators defined in world practice (level of availability and consumption of food, availability and sufficiency of food, quality and safety of food). The development of agricultural sectors depends on the intensification of investment strategies, state support in financing and investing, promoting the competitiveness of agricultural producers in the domestic market and protecting their interests in foreign economic activity, the introduction of credit mechanisms as an option to update the material base, improve the mechanism pricing, completion of land reform and direct control over the quality of production and use of natural resources.

In the article the development and substantiation of theoretical and methodological bases of formation of strategy of investment and innovative development of the enterprises in modern conditions of managing is carried out. It is determined that for enterprises operating in modern conditions, it is advisable to form an investment and innovation strategy, which is cross-functional and allows to agree on tasks in the field of innovation and investment in achieving the goals of the overall strategy. The essence of the innovation and investment strategy is based on the limited resources of development processes, given that investments act as an independent source of competitiveness and as a means of innovative development, but must be implemented in a better combination of investment directions. It is noted that the investment and innovation strategy must have a structural integrity in terms of resource use and impact on the enterprise as a whole. This strategy of the enterprise must be consistent with the overall strategy, contribute to the achievement of common goals, strengthen the competitive, financial, technological position of the enterprise, as well as create opportunities for further growth and development. The role of investment and innovation strategy is subordinated to the strategic goals of the enterprise and is transformed depending on the type and objectives of the overall strategy, can range from full focus on creating and implementing innovation to investment in support of current activities and sustainability. It is substantiated that the mechanism of investment and innovation strategy development includes a set of interrelated management tools, the application of which results in an approved investment and innovation strategy, one of the components of which is a list of recommended investment and innovation projects. The mechanism includes the following components: the approach to choosing the type of investment and innovation strategy, the profile of investment and innovation activities used to determine the direction of the pool of projects, which are then assessed for compliance with the criteria of consistency through economic and mathematical model selection of investment and innovation projects.
