Currently, Russia faces an urgent need for accelerated development of agricultural branches and rural infrastructure. The solution of the tasks of agricultural management is one of the most urgent problems of determining the reserves of growth of agricultural production in each of the Russian regions. In this regard, the authors set a goal to develop and evaluate correlation models describing the dependence of the volume of production of agricultural branches in the regions of the Russian Federation on the number of investments and the commissioning of fixed assets. The authors justify the choice of independent factors. The study was based on the economic and mathematical modeling of empirical spatial data, calculated on the basis of official statistical information on the regions of the Russian Federation. The conducted research permitted to identify factors, which directly determined the volumes of production in agriculture, to propose the use of high-quality correlation models to describe this effect, to prove that the economies of the examined regions did not reach saturation with agricultural products and there were significant reserves for their further development. The developed correlation models are effective tools for analyzing the development of the industry, and can also be used as management tools that allow for the assessment of the effectiveness of the use of the made investments, as well as the commissioning of fixed assets in the agriculture of each of the examined regions. The results of the research are of scientific and practical importance. They can be used in research and monitoring of agricultural development in the regions, determining the resource requirements, which are necessary for the development of agricultural industries, as well as the development of sectoral and integrated projects and agricultural development programs.
Currently, renewable energy (RE) is one of the core issues brought up monthly on the global market. The created green energy policy and support of the most advanced countries are aimed at its development. State-of-the-art technology, necessary scope of knowledge, and optimal conditions for using renewable sources of energy altogether are the factors for focusing on the development of the industry. The core purpose of the research was to reveal facts of the current formation of the RE sector. As a result of the research, we found out that the RE sector is currently achieving its peak of popularity. The issue is of worldwide relevance, and the leading countries focus their efforts on supporting the industry, while municipalities extensively implement such facilities in large cities. RE resources are also used in such areas as the transportation, cooling, heating, and energy industry, and many others.
