The aim of the study is to elaborate an econometric model to determine the conditions for ensuring the balanced development of environmental, economic, and social components of the Russian agricultural sector within the Eastern European region. The method of fuzzy sets was used to build an integral model for assessing the level of sustainable development of the agricultural sector in Eastern Europe on the basis of economic, environmental, and social sustainability indicators. The control indicators (independent variables) and integral economic, environmental, social sustainability (dependent variables) helped build multifactor linear regression models and calculate the indicators of elasticity of dependent variables from independent variables, which characterize the change in sustainable development indicators with the growth of controlling factors by 1%. This model allows us to define and analyze the levels of sustainable development of the industry, both in a specific country and within the region in general. The study shows that, for Russia and Eastern European countries, innovation is one of the crucial factors in ensuring sustainable development of agriculture in the region, taking into account the current state and level of economic development.

In 2018, only 1% of industry organizations use digital technologies, which reduces the competitiveness of Russian agriculture significantly. The relevance of the research topic is due to the low rates of implementation of precision farming technologies in agricultural production. The study aims to assess the motivational aspects and analyze the factors that promote and hinder the implementation and use of precision farming technologies by farmers. To achieve the goal and objectives of the study, a survey of farmers in the Sverdlovsk and Kurgan regions, as well as of employees of agricultural organizations was carried out. According to the survey results, the most favorable factors contributing to the implementation and use of precision farming technologies are the level of efficiency of agricultural production and the need to improve it; state support for their implementation; the level of development of the precision farming technologies market. The limiting factors for the implementation and use of precision farming technologies are the unsatisfactory financial conditions of a significant part of farmers, a high level of prices for precision farming technologies in comparison with traditionally used equipment, and poor availability of the personnel capable of mastering precision farming technologies. It should be noted that farmers are highly motivated to implement and use precision farming technologies, which are treated as an objective necessity, causing significant positive changes in agriculture in the nearest future. This allows us to conclude that there is a low level of workers' resistance to the implementation of these technologies.

According to the objectives of the federal project "Export of Agribusiness Products", the Far Eastern Federal District (FEFD) should increase the export of aquatic biological resources (ABR), including fish, to USD 1,338 million by 2024. Fish and fish products are among the top three agricultural exports in Russia (along with grains and oilseeds). The Far East is the main region in the Russian Federation for the capture of fish and other ABR. The article deals with the indicators of production and export of ABR of the fisheries industry of the FEFD, which includes also the Kamchatka Territory, Primorsky Territory, and the Sakhalin region. The authors consider problems that hinder its effective development and analyze directions and measures to solve existing problems. The main negative factors are associated with the infrastructural shortcomings, such as physical and moral deterioration of the fishing fleet, the lack of modern processing facilities, which do not allow producing fish products with high added value in the proper amount. To develop the concerned industry sector and resolve the issues constraining the growth of production and export capacity in the entities of the FEFD, the Russian government has developed special programs to promote investment activity, the construction of the necessary fishing fleet and infrastructure facilities, and modernization of existing facilities.

The article discusses the essence and stages of the formation of a new field of knowledge – the economy of the World Ocean. The importance of sustainable approaches to the economic development of the marine industry is shown. The authors performed an analysis of the bioeconomical essence of industrial entrepreneurship. The dynamics of the components of the bioeconomical analysis is substantiated. The interrelation and mutual influence of these components is revealed. In bioeconomical assessments, significant databases containing diverse and high-quality indicators related to the need to choose an alternative based on methods related to different fields of knowledge are involved in the analysis. The authors of the article believe that in situations involving a large number of variables, modeling and mathematical programming techniques are the most effective means for making managerial decisions. These methods are justified in the article.
