For the Ukrainian population, there are factors surrounding the choices and preferences one must consider when changing permanent residence. Smart residential areas should be built according to Ukrainian legislation and global innovations, which would reduce administrative dislocations, the load on megalopolises, and negative anthropogenic impacts, and should be based on the increase in energy efficiency and reducing waste. We analyzed the core principles of designing smart residential areas and concluded that constructing cutting-edge residential areas should involve private investments in order to avoid shadow schemes and irrational use of funds (in the Ukraine, the share of the shadow market is more than 50%). Research shows that, as humans inhabit a three-dimensional space, it is possible to predict migration and other permanent residence/behavioral responses, the analysis of which allows controlling migration flows and improves the conditions of Ukraine’s small residential areas based on decarbonization. We conclude that energy saving systems can reduce consumption in a city by 60% and improve Ukraine’s ecosystem. Research also shows that reducing “dislocation”, in terms of population density, by creating open, innovative, eco-friendly environments based on green economy principles, can provide innovative development maps and economic, social, and cultural population growth, decreasing the load on big cities/regional economies, and encourage the restoration of sales markets and production after the COVID-19 pandemic. We developed a model to assess the innovativeness of residential areas, apply alternative methods of energy generation, and analyze the impact of the energy production and consumption market in Europe (with recommendations for the Ukraine). This article estimates energy intensity indicators of the gross domestic product in the Ukraine and in Europe, offering methods to decrease energy dependence and increase energy efficiency in the Ukraine, by adopting alternative energy sources (e.g., biohydrogen out of residues, air, and solar energy), and enhancing environmental legislation.

The current state of development of Ukraine’s national economy involves strengthening the processes of transition to social market economy, aimed at accelerating the rates of economic growth of the country. The presence of peculiarities of activity of agrarian producers and increase of the socioeconomic importance of the agrarian sector of the economy contribute to the need to develop and substantiate the methodological conditions aimed at solving multidimensional and diverse problems of ensuring the development of agrarian economic systems. In the work, the directions of the formation of the mechanism of management of agrarian economic systems, which consist in the transition to a new quality level of the use of information and intellectual resources of the management system on the basis of modern information technologies and modeling, which allowed to develop a structural scheme of the mechanism of management of the agrarian sector of the economy. The understanding of the mechanism of management of agrarian economic systems, factors and functions of this mechanism are determined. The mechanism of management of agrarian economic systems should be considered as a system of principles, rules, norms and procedures, within the framework of which the goals and objectives of the agrarian economy are developed in accordance with the current economic laws. This mechanism should be in line with the ownership of the subjects of state domination of the region, organizational structures of management, market social and economic relations, natural conditions of economic activity and state economic policy concerning the development of agrarian production, etc., and also take into account the main economic relationships that exist between the individual structural components of the agrarian economic system.

To increase the level of management efficiency in the agricultural sector of the economy, it is necessary to sub-stantiate environmental protection measures for the restoration and rational use of natural resources, to ensure the implementation of the sustainable environmental management principles, considering the spatio-temporal patterns of changes in climate and bioclimatic potential of the territory. Using the methods of multivariate statistics and time series forecasting, regularities of changes in climatic conditions in the Steppe zone of Ukraine for 1945-2019 were established, and a forecast of changes in the bioclimatic potential of the region until 2030 was made. It was established that during the research period the average annual air temperature increased by 3.5 degrees C. The amount of annual atmospheric precipitation varied within 186-778 mm with a variation level of 27.2%, in the last 20 years it was determined to decrease by 40% - to 500-300 mm. It has been proven that the inertial probability of repeating hot years is estimated at 0.58, and the possibility of repeating wet years at 0.46. As a result of forecasting, it was determined that if the trend of climatic conditions is maintained, there will be a stable trend-cyclic increase in the average annual air temperature by 0.06 degrees C per year and a decrease in the amount of annual precipitation by 62.0 mm per year. This resulted in an 18.7% increase in solar radiation on the soil surface and a 26.0% decrease in cli-matic losses on soil formation, which reduced the rate of the natural ability to reproduce soil fertility. In particular, the bioproductivity of plants decreased by 62.0%, and the probability of its further decrease by 20% is predicted. Over the past 20 years, the coefficient of natural humidification has decreased by 66.4%, and it is predicted to decrease by 20%. The obtained results confirm significant climatic changes and their negative manifestations on the reduction of bioclimatic potential in the Steppe zone of Ukraine, the deterioration of agricultural production conditions, the reduction of harvests, the self-regenerating and self-regulating function of steppe soils.

Introduction. This article presents a study of the role of the modern energy market in the management of resource conservation and resource efficiency of competitive enterprises in the agri-food sector of Ukraine. The study uses monographic, economic-statistical and abstract-logical scientific methods of economic research. The purpose of this article is a comprehensive study of the role of the energy market in the management of resource conservation and resource efficiency of competitive enterprises in the agri-food sector. Results. The article proves that the effective development of domestic agricultural enterprises largely depends on the stability of the production needs of diesel fuel and gasoline, it should be noted that the key role is played by the stability of prices for these types of energy resources. The modern world tendencies of hydrocarbons use and products of their processing taking into account resource saving and resource efficiency are investigated. The current directions of energy saving and ways to save fuel and lubricants are formed, the problems of their use in the agricultural sector of Ukraine are investigated. Factors influencing the national energy market are systematized, taking into account the specifics of agricultural production. The structuring of fuel consumption in agricultural enterprises of Ukraine and fuel consumption in agriculture in physical units is carried out, the receipt and availability of gasoline and diesel fuel in national agricultural enterprises are analyzed. The dynamics of prices for the main types of fuel used for agricultural production is analyzed. Conclusions. The scientific novelty in this article is the systematization of fuel suppliers in the regional market, which made it possible to identify their dependence on industrial and financial groups. The offered possibilities of own capacities use for storage of oil products in the agricultural enterprises have practical value in the presented scientific research. Prospects for further research in this area should be directed to such an important area of educing the use of fuels and lubricants as the use of modern technologies for basic tillage and soil preparation for crops. Key words: energy market, management, resource saving, resource efficiency, competitive, enterprises in the agricultural field.

The article proves that the investment support for the competitive development of the agrarian sector is directly influenced by both structural changes and measures to create alternative mechanisms for investing in the agrarian sector of the economy. It is substantiated that the agricultural sector occupiesan important place in the economy of many countries, including Ukraine. Its development depends on many factors, but one of the most important is investment. By investing in the agricultural sector, you can achieve positive results and ensure the sustainable growth of agriculture. One of the areaswhere investments can have a significant impact on the agricultural sector is technology. This is also related to plant breeding, animal breeding and aquaculture, as an industry that is promising in terms of the development of the national economy and is directly related to the economic and national security of the country within the framework of transformational processes and in conditions of high volatility of economic cycles. The basic components of investment support for the competitive development of branches of the agrarian sector of the economy are proposed. It has been proven that currently we can state a situation where it is important to consider various forms of investments that can contribute to the strengthening of the agricultural sector, taking into account the economic effects of activities for public interest groups. Returning to the global goals of sustainable development by 2030 announced inthe resolution, it is important to adhere to the points on ensuring the availability and sustainable management of resources, their conservation, as well as their rational use, defined in the Decree of the President of Ukraine "On the Goals of Sustainable Development of Ukraine for the period until 2030".Therefore, measures and methodical approaches to identifying effective tools for assessing the structural transformation of the domestic economy are becoming more relevant. Scientific and practical explorations were carried out to find ways of regulatory aspects of investment support in the agrariansector of the economy. This made it possible to make sure that it is now important to take into account structural changes in the economy in a timely manner, taking into account methodical approaches to modeling the impact of politics on agriculture. And even in the case when we talk about the process of investment support, as well as raise and reveal the problematic issues of competitive development of the agrarian sector of the economy, taking into account structural changes and the economic effects of activities for public interest groups, we must undoubtedly also adapt indicators of economic efficiency.Economic efficiency indicators have been adapted. It is substantiated that these indicators should be applied to various branches of the national economy, since they are in the system of general economic categories and are suitable for adaptation in the implementation of any type of entrepreneurial andeconomic activity. Attention is focused on the calculation of economic benefits, as well as the costs of small and medium-sized businesses in territorial communities, where the costs and benefits of society are taken into account, as well as their comparability, taking into account the impact of the economiceffects of activities for all groups of public interests.
