Optimization of interaction of agrarian entities as an imperative of ensuring food security of the state

Abstract
The interaction of agricultural entities is based on modern market relations and the state agrarian policy. Managing the subjects of the agricultural sector of the economy is the primary task of the state, since the provision of food security of the state depends on this. The subject of the study is the establishment of relations of the agricultural sector of the country. In the grouping method, a direct relationship was established between the sum of agricultural production in farms of all categories in the constituent entities of the Russian Federation and the number of employees in the regional agro-industrial complex of the agricultural sector, as well as the number of departments in them. The purpose and objective of the study is to highlight the main functions of state administration of the agricultural sector at the regional level, to identify the lack of an effective mechanism for interaction of the subjects of the agricultural market with each other and with the regional authorities of the agricultural sector. The presented model of optimizing the relationships between the agrarian entities of the region will increase the efficiency of the agrarian sector of the region’s economy and ensure its food security. The necessity of planning and forecasting the volumes of production and use of agricultural products and raw materials is substantiated. The system of such forecasting includes such subsystems as agricultural enterprises, processing enterprises, and the population of the region. It is concluded that each subsystem works on a well-formed and well-founded functional model, which includes input and output information, controls that regulate functioning, as well as mechanisms that ensure such functioning. A special role in the forecasting process is assigned to the regional management bodies of the agro-industrial sector represented by the department for optimizing the interaction of agricultural entities in the region. The final forecast result should be a balance model of the degree of food security in the region's population.
