Entrepreneurship and Sustainability Issues is a peer-reviewed journal which publishes original research papers and case studies

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.

Optimization Model for the Russian Electric Power Generation Structure to Reduce Energy Intensity of the Economy

The main idea of this article is the justification of the necessity and the creation of conditions for attracting investments in economic entities of agrarian and agro-industrial production. The authors consider topical issues of increasing the investment attractiveness of industries and businesses in agro-industrial production of the subsidized region at the federal and regional levels. The authors note that ensuring the food security of the administrative district, the region and the country as a whole largely depends on the solution of this largescale task. The forms, methods and mechanisms affecting the activation and inflow of investment and financial resources into agro-industrial production are exemplified by the subjects of the North Caucasus Federal District (in particular, the Chechen Republic). The subject of the study is the organizational-economic relations connected with increasing the investment attractiveness of the agrarian sector and agro-industrial production. The article gives authors' definition of the economic category of the "investment attractiveness". The results can be used by the government of agro-industrial production of subsidized subjects of Russia in the development and implementation of regional agricultural development programs and regulation of markets for agricultural products, raw materials and food, as well as social development of rural areas.

The study is aimed at determining the oscillators of crisis manifestations when the Russian economy tries to make transition to the path for accelerating technological development and forming an innovative economy. Short-term cycles were determined in the development of the Russian economy from 1995 to the first half of 2020 through the Fourier spectral analysis. Using the Granger test, causal relationships between the leading indicators of the economic crisis and the real GDP index in Russia were identified and substantiated. They reflect the influence of the key rate dynamics on the volume of lending, savings, investments, the yield on securities and the exchange rate; volumes of bank loans per the share of non-performing and bad loans and innovative development of the economy. Based on the constructed neural models of the oscillator influence on the level of real GDP in Russia, it was determined that the rapid growth of bank and mortgage lending, the devaluation of the ruble, a decreased volume of gross foreign investment and the level of innovative development predetermine crisis manifestations in the national economy. The lags of the influence of changes in the leading indicators of the economic crisis on the development of the economy were calculated. The results obtained can contribute to the effectiveness of the anti-crisis regulation strategy in Russia. They can serve as a basis for increasing the efficiency of long-term innovative development and creating appropriate conditions for increasing the scientific and technological potential of the country.

The article presents the analysis of the integration processes that are taking place in the Eurasian Economic Union (EAEU), the unified agro-food policy developed by the participating countries, as well as strategic measures and mechanisms for further interstate integration in the field of agro-industrial production. The article pays special attention to the issues of receiving the real economic (positive) impact from the integration through mechanisms promoting a coordinated agrarian policy.
