Introduction. The resources of the business entities of the machine-building complex increasingly determine the importance of developing the components of the internal efficiency of the industry itself and ensuring the national security of Ukraine, since the machine-building complex is the leading branch of the national economy. In this regard, an urgent task is to form a methodological basis based on the concept of the development of the machine-building complex using a system of measures of direct and indirect regulation and improvement of the strategic directions of industrial policy. Aim and tasks. The purpose of the paper is to substantiate the essential characteristics of the economic security of the machine-building complex, as well as to study the approach to implementing the concept of the development of the machine-building complex based on the application of methodological contexts. The paper examines the essential and practical characteristics of implementation the concept development of the machine-building complex in the context of methodological basis based on safety-related conditions. Results. The evaluation of the effectiveness of the implementation of the existing concept using the model for selecting target indicators is substantiated, as a result of which the main vectors for ensuring the safety of machine-building enterprises in modern conditions of challenges and threats are identified. In addition, three design stages of the implementation of this concept are characterized and the features of ensuring the relevant safety components in the conditions of the intensification of the development of the machine-building complex are studied. Conclusions. A distinctive feature of the management of the economic security system of machine-building enterprises is the ability to use operational, tactical, strategic, and preventive mechanisms for diagnosing, stabilizing, and ensuring the economic security of machine-building enterprises. The proposed concept allows assessing the prospects for the development of a machine-building enterprise, developing its tactics and strategy, and reducing the consequences of financial crises and the negative impact of new threats and dangers based on the practical application of the concept of developing the complex under study using predetermined methodological contexts.

Abstract The article proves the necessity and expediency of using financial leasing by extractive industry enterprises to minimize the cost of purchasing, using, maintaining equipment and maintaining production capacity. Foreign and domestic financial leasing practices analyzed and their direct impact on the development of the country’s economy is determined. Financial leasing will become more accessible and understandable for enterprises of different sectors of the economy after the entry into force of the Law of Ukraine “On Financial Leasing”. The analysis of the value of the concluded financial leasing agreements by sectors of the economy carried out and their basic tendencies defined. It is determined that the volume of concluded financial leasing agreements by extractive industry enterprises has a small share in comparison with other branches of economy. The analysis of the effectiveness of structural changes confirm the low demand for financial leasing by extractive industry enterprises. It is determined that the use of financial leasing by extractive industry enterprises will expand existing production, introduce the latest technologies, minimize costs for the purchase, use, maintenance and upgrade of equipment and means of production.

The paper represents the analysis, which has helped to establish the usage of gas hydrate technologies in the methane conversion. This gas could be obtained in different ways. Possibilities and sources for the gas obtaining have been demonstrated. Use of other environmentally friendly sources to support operation in such systems in terms of joint energy complex has been considered. The necessary kinetic connections to provide operational sustainability of all the constituents have been given. The approach helps evaluate quantitatively the priority of its physicochemical transformations to obtain gas hydrates artificially. It is possible to transport methane at considerable distances when it is solidified. Actually, in this case there is no necessity to build costly compressor stations and pipelines for its transportation to consumers. The approach is extremely important for mining regions as it helps prolong the operating period and working out of the abandoned and off-balance coal reserves. In this case, it is proposed to apply special gasification technologies tending to maximum methane recovery. The proposed solutions give the possibility to define the trends of our further research. They will be highlighted in the following authors’ studies.

The article is devoted to main theoretical and practical questions concerning “green” investments in logistics infrastructure objects. This type of investments has certain peculiarities as it deals with the sphere which is related to any kind of business and human’s activity. Logistic infrastructure forms mobility. But no significant change in a separate facility will not give a significant result without a support to the relevant network and the highest intellectual level of its use. Planning of logistic infrastructure should be performed in such way that the positive effect on economic growth was maximal, and the negative impact on the environment is minimal. Thant’s why improving logistics infrastructure facilitates achieving sustainable goals as it works simultaneously for economic, environmental and social development. Thus it is extremely important to implement such tool from “green” economy concept as “green” investments towards logistics infrastructure objects. There were analyzed different theoretical approaches to the definition of “green” investments in the paper. The result of deep research of worlds’ best practical trends for “green” investing in logistics infrastructure objects is provided. There studied separately mentioned tendencies for all subtypes of hard logistics infrastructure: transport (electrification of vehicles, low-carbon transport systems, sustainable fuels), warehouse (automation, distribution centers decentralization, energy-efficient equipment and construction), packaging (suitable for processing packaging materials, moving from plastic to more environmental types of packaging), information infrastructure (energy-efficient servers, cloud computing, reducing the number of toxic materials and water required for the production of electronic devices), customs (The Green Customs Initiative), social (smart containers, automated food waste tracking systems and automated technologies of optical scanning). Also were studied main instruments to attract necessary finance support for “green” investments and analyzed ways how to implement them in Ukrainian market with its peculiarities.

The paper considers the transformation of human resource management processes in the healthcare settings of Ukraine in the context of war and the COVID-19 pandemic. It is noted that the unstable and hostile environment of a healthcare setting during times of crisis leads to the need to change the personnel selection and team formation model to increase the adaptability and resilience of human resources involved in the provision of medical care. The key features of the human resource management process in a turbulent environment are the high migration activity of personnel, which leads to the need to reallocate resources, the need to operate under severe financial constraints, and the need to consider personnel as a non-renewable resource when it is impossible to attract additional resources. To ensure the reliability of the functioning of a medical institution, the transformation of human resource management processes should be based on strategic agility and human resource management, organizational resilience as a resource-based capability, corporate sustainability, and transformation of enterprises’ resources, which can be achieved by applying methodological support for resource management in a multi-project environment. Considering a network of medical institutions as a multi-project environment will allow using the methodology of project-oriented resource management, forming adaptive teams in a multi-project environment, to ensure flexible redistribution of resources both within a single institution and within a network of institutions. It is proposed to use formal transformations to manage a medical institution’s human resources. Applying the proposed approach for managing the human resources of a medical institution is considered. The formation of a project team that satisfies the minimum requirements with the maximum value of the team’s qualification score is considered. It is shown that the use of this methodological support made it possible to choose the composition of the project team with a minimum number and a maximum value of the characteristic.

The paper presents the comparative analysis of the amount of waste generated in Ukraine and European countries (except for radioactive waste) based on the official EU and Ukrainian statistical data. The data on waste generation are compiled according to the following classification: by economic activity and household, waste category, grades of hazard, and regions. In Ukraine, 352.3 million tons of waste was generated in 2018. By 2018, almost 13 billion tons of waste had been accumulated at the managed dumpsites, including about 12 million tons of hazardous and over 200 million tons of household waste. In the European Union, 2.6 billion tons of waste was generated in 2018. Over 70% of it was generated by 10 countries: Germany, France, England, Poland, Romania, Italy, Sweden, the Netherlands, Spain and Finland. By economic activity, the largest amounts of waste in Ukraine are generated by the mineral extraction and processing industry, the smallest – from water treatment and construction. In the EU countries, these values are somewhat different. For example, in Germany and France, the largest amounts of waste are generated from construction and manufacturing, the smallest – from agriculture, forestry and fishery. By waste category, the waste generated both in the EU countries and in Ukraine is mineral and solid waste. In Ukraine, the largest amounts of waste are produced and accumulated in the Dnipropetrovsk, Donetsk and Zaporizhzhia regions which accommodate large enterprises for extraction and mineral processing of iron and manganese ores, titanium-zirconium placers, coal, dolomite, and metallurgical limestone, as well as metallurgical and ferroalloy plants.

This article highlights the impact of innovation on achieving environmental sustainability of regional economic systems in the context of effective man-agement of significantly limited natural resources in modern Ukraine, which was the subject of the study, its key objective and main task. Methodology. The proposed work uses systemic and synergetic approaches, methods of analysis and synthesis, induction and deduction, historical and comparative analysis, etc. Value/originality. Consideration of the issues of regional innova-tion and environmental sustainability of regional economic systems in their combination is a novelty in modern studies of ecological-economic processes. It is exhaustively taken into account that innovation is a complex process of transformation of newly obtained ideas and goals into an actual object of eco-nomic relations. At the same time, it was found that in the conditions of trans-formation of the modern Ukrainian economy began to manifest such features as frequent and unpredictable changes in demand due to the emergence of completely new needs, which can be satisfied only by qualitatively new, pre-dominantly knowledge-intensive products. Therefore, there is an urgent need to restructure regional economies on a fundamentally new basis, which provides a real opportunity to reproduce the existing innovation potential, improve the innovation and technological level of all spheres of economic activity in the re-gion and achieve a much higher degree of competitiveness. At the same time, given the significant role of innovation processes in improving and ensuring the proper environmental sustainability of regional eco-nomic systems, the def-inition of appropriate tasks, taking into account their characteristics, is a pre-requisite for the effective management of natural resources of the country as a whole and its regions. Therefore, in European practice, the European Innova-tion Scoreboard (EIS), calculated by Eurostat, is used to determine the achieved level of regional innovation development. At the same time, the methodology used in its basis to assess the effectiveness of national research innovative projects is not without criticism. And one of the main criticisms was the absence of a conceptual or theoretical model of innovation. Simultane-ously, this paper proposes a fundamentally new approach to determining the effectiveness of innovation in the hierarchical-regional dimension, which is based on the use of appropriate tools of multidimensional statistical analysis and statistics of the European Union (in particular, Eurostat) and the State Statistics Service of Ukraine. In addition, synchronously with their standardi-zation, based on the obtained values of innovation levels in the regions, matri-ces were formed separately for incoming and outgoing regional innovation in-dices. Result. The achieved levels of innovativeness of Ukrainian regions in the context of ensuring appropriate environmental sustainability of their economic systems in the management of significantly limited natural resources were de-termined. Practical implications. Another real opportunity has arisen to signif-icantly improve the management of the available natural resources of each re-gion and the state as a whole in terms of ensuring the proper environmental sustainability of regional economic systems.
