The article examines the state of Ukraine’s military economy and forecasts of its reconstruction. It is noted that one of the ways for a country to survive is to maintain the productive capacity of its economy, which reflects the efficient use of all resources, the quality of human capital and sustainable development. The essence and approaches to assessing the productive capacity of Ukraine, in particular according to the Productive Capacities Index (PCI), have been revealed. For the development of the European KLEMS productive capacity model, a formalized model and an approach to deepening its informational component are proposed. The factors of the “technological leap” that can be drivers of the development of productive capacity have been highlighted. The authors have proposed to consider productive capacity through the prism of sustainable development and its goals (SDGs). The “ecological footprint” has been described, which as of 2021 is 73% higher than the possibility of renewing the world’s ecosystems. The paper also covers a comprehensive approach to overcoming this risk (Twin-strategy) based on a combination of economic (but only within ecological) and social determinants of sustainable development. It has been noted that a bilateral “green” and “digital” strategy for the transition to the next stage of sustainable development (Twin Transitions for Global Value Chains) is relevant. A foresight approach to reducing gaps in the development of countries’ economies using advanced “green” technologies has been described.” It is summarized that in order to increase the productive capacity, Ukraine needs to rebuild the economy on the principles of Industry 4.0 with robotized production at “smart” factories. It has been studied that according to the Frontier Technologies Readiness Index, Ukraine belongs to the group of countries with an above-average level of the index. Recommendations on research and management of production potential for the reconstruction of Ukraine’s economy and its growth in the context of a bilateral “green” and “digital” strategy of sustainable development are given.

The main idea of this paper is the substantiation of the methodological approach to the assessment of personnel risks of enterprises based on the application of the fuzzy logic apparatus in order to identify the problems of personnel risk management and provide appropriate recommendations for their solution. The methodological basis of the study is the classic provisions and fundamental works of foreign and domestic scientists, statistical data, the results of our research into the problems of assessing personnel risks of enterprises. The methods of fuzzy set theory, comparative analysis, scientific abstraction, generalization of scientific experience of modern theoretical research, systemcomplex approach were used. The study proposed a methodological approach to assessing the level of personnel risks of an enterprise; numerical experiments were conducted on the basis of a group of construction equipment manufacturers. Analysis of the results of assessing the level of personnel risks of enterprises made it possible to identify the problems of managing personnel risks at enterprises Statement of a mathematical problem: the work considers hierarchical fuzzy data, namely: four groups of indicators for assessing the level of personnel risks (quantitative composition – F1, state of qualifications and intellectual potential – F2, staff turnover – F3, motivational system – F4), each of the indicators has a different number of fuzzy coefficients (there are twelve of them in the current work – vi , i=1÷12). Indicators are functions of fuzzy coefficients: F1 = r(v1, v2, v3); F2 = g(v4,v5, v6, v7); F3 = h(v8, v9, v10,); F4=q(v11, v12). As an output variable, there is a functional – an integrated indicator Int = f(F1, F2, F3, F4) of the personnel risk level, which, in turn, is also a fuzzy value.

The study of the problems of improving the mechanism of the management of the factors that slow down the development of the non-oil industry confirms the instability of the development rates of the Azerbaijani industry in 2005-2021, the disparities in the development of the industry in the production and processing areas, as well as in the regions. As a result of the study, the classification of internal and external factors that hinder the development of the non-oil industry is justified. Application of ISO standards in enterprises operating for the creation of a non-oil industry based on innovative economy, a new concept of regulation of production activities based on the data of technical projects, technical and economic justifications and project estimates were presented as the main direction of improving the management system of factors that hinder the development process of the non-oil industry. The relevance of the subject. In recent years, factors such as creating an inter-sector balance and effective use of natural and material resources have played an important role in ensuring economic stability in our country, but it is necessary to solve the economic and institutional regulation issues related to the development of the non-oil sector of the industry. Because ensuring the development of the non-oil sector has been set as a priority direction and main task of the state’s economic policy. The main goal in the implementation of the specified task is to increase the level of welfare of the population, transition to an export-oriented economy and improve the competitiveness of the economy. From this point of view, the relevance of the research of the subject is not in doubt. The purpose of the article.

The article examines the complex of digitization functions of marketing resources in conditions of economic uncertainty, their interrelationship, and the proven direct impact of the digitization process on the efficiency of enterprise management. It is concluded that modern business structures use digital technologies as a competitive advantage in all areas of their activity: operational processes, business processes, finance, marketing and interaction with market stakeholders. On the basis of the positive correlations summarized by the authors, it can be assumed that the efforts aimed at the digitization of processes can be considered as a managerial innovation that ensures the growth of innovations and increases the efficiency of the functioning of the business structure. On the basis of a systemic approach, the authors substantiated and built a complex functionality of the process of digitization of the company’s marketing resources. In the architecture of complex functionality, the digitization process is determined by the digitization functions of marketing resources, in particular: analytical (data collection and analysis), communication (Internet advertising), sales (sales via the Internet), and the function of regulation and control (regulates and controls the digitization processes of the marketing department). The synthesis of the theory of random processes together with the systemic approach enabled the authors to define marketing resources for enterprise activities as a complete functional dynamic system with a discrete state, in which for each moment of time the economic security of the enterprise in the future depends on the current state of digitization and does not depend on how this state was reached. The prognostic and transformational probabilistic method for determining the effectiveness of digitization of marketing resources of an enterprise’s activities is proposed, which combines the potential of the enterprise’s marketing resources and the functions performed by marketing and allows for taking into account factors of the internal and external environment, the influence of which causes the emergence of risky situations that lead to unjustified losses of the enterprise. The authors have proven the effectiveness of using digital marketing tools within the scope of each marketing function to prevent the occurrence of risky situations in the company’s activities. Within the framework of the analytical function of marketing, a study of the competitive environment has been carried out, the market share of the enterprise has been recognized, an estimate of costs for marketing research has been prepared. Indicators of the communication functionality of marketing activities in the total amount of marketing expenses complement and justify its decisive influence on the general state of not only marketing, but also the entire economic activity of the enterprise.

The aim of this study is to determine the number of transactions among the currencies, which will eventually become a part of our lives, cannot be physically held, can move quickly, and emerge as a new shopping and investment tool in the changing world order, as of the year (2023) when this study was conducted. The study focuses on the analysis of the variables that affect the most popular currency, Bitcoin. Although the analysis of variables that influence Bitcoin was determined as the primary aim of the study, the study also attempted to reach a general conclusion about the variables affected by the cryptocurrencies. Since there is no other cryptocurrency that is traded as much as Bitcoin, Bitcoin is thought to be a good model for the analysis of cryptocurrencies. The method used in the study was autoregressive conditional heteroskedastic (ARCH) models. It is believed that the most suitable models for the Bitcoin variable, whose value changes every second, are ARCH and its derivatives. Other models selected from the ARCH models were also added to the analysis as a method. The models used in the study can be listed as follows: linear ARC, generalized ARC (GARCH), exponential GARCH and threshold GARCH. A statistical model called autoregressive conditional heteroscedasticity (ARCH) is used to study the volatility of time series. Through the provision of a volatility model that more closely mimics actual markets, ARCH modeling is utilized in the financial sector to quantify risk. According to ARCH modeling, periods of high volatility are followed by even higher volatility, and periods of low volatility are followed by even lower volatility. In this study, 5 different variables were selected using literature to analyze the variables affecting Bitcoin returns using ARCH models. The dependent variable in the study is the price of Bitcoin. The remaining variables were included in the models as independent variables. These variables are actually variables that are accepted and selected as the best among a set of variables. In other words, 15 variables were first added to the study using the literature. After this, a correlation analysis was carried out. As a result of the correlation analysis, the variables with the highest correlation with the price of Bitcoin, which is the dependent variable, and the lowest correlation with each other were retained in the model. These variables are Bitcoin Price, Crude Oil Spot Price, Euro-Dollar Parity, Gold Spot Price and NASDAQ Composite Index. The study period is between 2020 and 2023 and it was studied using daily data. Days with no data were removed from the daily period from 2020 to 2023 and loss of information was prevented. After removing missing observations, this study examined the remaining 837 observations. During the research, while running the models created using different methods, it was found that the model that gives the best result is the GARCH model.

Enterprises develop and interact with the global environment. Their activities are influenced by various factors, and timely identification of the degree of their influence allows forecasting business development and reasonably choosing development strategies. The work is based on the hypothesis that in the global environment, under the influence of internal and external factors, tools can be developed for enterprise assessment and business strategy formation. The puprose of the paper is to develop a toolkit for evaluating an enterprise in a global environment for choosing a development strategy. In the article, the authors conduct a study of the influence of factors of the global environment on the development of the enterprise, propose a model with the help of which it is expedient to forecast the metastate of the enterprise and put forward proposals for choosing an effective development strategy. A structural and logical model for ensuring the stable development of business systems has been proposed. In the process of research, the authors developed a system of indicators that form an integral index that characterizes the effectiveness of the development of business systems. The basis of the integral indicator of the metastate of the development of business systems is a set of indicators for assessing the development and changes in the state of business systems in a dynamic global environment. The economic and mathematical model of estimating the metastate of business systems is considered as a reflection and formalization of the main, essential parameters of business systems development (production, technological and property, personnel, social, financial, material and supply, marketing, foreign trade. The integral metastate index of business systems systematically reflects the effectiveness of the Kharkiv machine-building business systems and allows determining strategies for their development. The selected machine-building enterprises have been grouped by the following types of development strategies: a rapid growth strategy aimed at ensuring the development of enterprises, offensive positions; a strategy of moderate growth and stabilization, characterized by stable parameters of business systems development, adequacy of resources for development, aimed at saving resources and costs, market expansion and development, product upgrades, innovative development; a strategy of curtailment, reduction, which is characterized by negative development trends due to lower profits, reduced assets, reorientation of consumers to other products or markets. As a result of the research, a methodological approach to the assessment of trends in the development of business systems has been developed, which will allow obtaining additional advantages in the global environment. Determination of benefits becomes a basic characteristic for monitoring information provision regarding the organization of enterprise activities in a global environment. The paper makes a

In the process of research, the authors developed a system of indicators that form an integral index that characterizes the effectiveness of the development of business systems. The basis of the integral indicator of the metastate of the development of business systems is a set of indicators for assessing the development and changes in the state of business systems in a dynamic global environment. The economic and mathematical model of estimating the metastate of business systems is considered as a reflection and formalization of the main, essential parameters of business systems development (production, technological and property, personnel, social, financial, material and supply, marketing, foreign trade. The integral metastate index of business systems systematically reflects the effectiveness of the Kharkiv machine-building business systems and allows determining strategies for their development. The selected machine-building enterprises have been grouped by the following types of development strategies: a rapid growth strategy aimed at ensuring the development of enterprises, offensive positions; a strategy of moderate growth and stabilization, characterized by stable parameters of business systems development, adequacy of resources for development, aimed at saving resources and costs, market expansion and development, product upgrades, innovative development; a strategy of curtailment, reduction, which is characterized by negative development trends due to lower profits, reduced assets, reorientation of consumers to other products or markets. As a result of the research, a methodological approach to the assessment of trends in the development of business systems has been developed, which will allow obtaining additional advantages in the global environment. Determination of benefits becomes a basic characteristic for monitoring information provision regarding the organization of enterprise activities in a global environment.

The article notes that in the context of globalization, multinational corporations exert an increasing influence on the economies of their home countries, host countries, and the overall state of international economic relations. The authors underline that tax planning is one of the TNC activities that grabs attention of the global public in terms of both its favorable and unfavorable effects. The article offers its own definition of the term «tax landscape», in which, unlike the existing ones, vertical, horizontal and temporal aspects are distinguished. The vertical aspect is presented as a synthesis of the supranational level of taxation and the national one; horizontal, as a system of tax rules and laws within a separate state; temporal, as a change in the main elements of taxation over time. It has been proven that at the current stage of formation of tax landscapes to characterize the supranational level, it is necessary to take into account the elements of taxation defined as part of the implementation of the international BEPS project: the global minimum tax, tax rates for surplus profits, and surplus profits as an object of taxation. The authors have been able to divide the studied countries into three groups depending on the level of direct taxation: high (United States, Canada and Australia), moderate (Great Britain, France, Italy, India, Germany and Switzerland), and low (China and Saudi Arabia). The first group (the United States) and the second group (the United Kingdom, Germany, France, Switzerland, and Italy) have been found to have the greatest tax losses as a result of «tax havens.» The level of direct taxation (profit and capital) in the countries of registration and countries of digital presence, the volatility of tax legislation, and compliance with the conditions of tax justice have been proposed as factors of the tax landscape to be taken into account by transnational corporations when developing tax planning strategies.

The article is aimed at researching the capitalization of intellectual potential based on the analysis of the indicators of the created multi-level model to increase the efficiency of the use of human resources both in individual organizations and in the country as a whole. Theoretical aspects of intellectual capital management, structural components and approaches to its evaluation have been considered and summarized. It has been determined that insufficient attention is paid to intellectual potential as a capitalization resource in modern research, and the assessment of the capitalization of intellectual potential from the point of view of the income approach causes conflicting opinions among scientists. At the institution of systematization of scientific research, its own view on the concept of “capitalization of intellectual potential” has been substantiated and formed. It has been proven that the management of capitalization processes of human resources at the micro and macro levels is a determining factor of economic development, as it contributes to the growth of the value of assets and the quality and well-being of the population. A multi-level model of the process of capitalization of human potential has been proposed in order to reflect the cyclical transformation of human capital in the creation of added value and to reveal the possibilities of improving the management of the process of capitalization of human potential when combining the resources of education and entrepreneurship. It has been established that the level of capitalization of the intellectual capital of Slovakia is several times lower than the level of capitalization of the labor potential, which indicates a decrease in the prestige of education and the need to deepen the knowledge and skills obtained at the level of general secondary education. Based on the results of the analytical observation, a number of negative factors affecting the indicators of the level of capitalization of intellectual potential have been revealed. It has been established that at the global level, Slovakia’s economy has three times less ability to capitalize intellectual potential than most developed European countries, which indicates a much lower level of competitiveness of Slovakia in terms of attraction, use and development of intellectual potential. Strategies for the development of higher education have only a formal nature, which affects the real management of the system, and long-term priorities are not translated into other areas of the functioning of institutions, such as marketing, partnership development and strategic management of human resources. To date, the topic of cooperation between the educational and business sectors remains one of the most controversial and problematic, since the education system, which has been operating for years, has been rather slow in implementing the latest management methods and does not take into account mutual readiness for cooperation.

The article is devoted to the analysis, comparison and evaluation of the effectiveness of the foreign exchange policy instruments used during the crises of 2008-2009 and 2019-2020 in Ukraine. The main types of instruments of foreign exchange regulation and the priority areas of their application were defined. The authors took under consideration the key features of the construction of the socioeconomic model of Ukraine, the geopolitical situation, and the imposition of cyclical fluctuations during the considered periods. In the course of the study, the exchange rate fluctuations of the national currency against the US dollar were monitored to determine dynamics of the devaluation and revaluation processes within the given time frames. In order to detail the regulatory foreign exchange policy, a separate analysis of the use of NBU tools within the current and long-term strategy was carried out, the differences were identified and the consequences were outlined. The conducted research showed that during both crises the discount policy, namely the change in the discount rate, was most actively used. But the changes were somewhat divergent: more aggressive liberal measures taken to reduce the discount rate during the 2019-2020 crisis appeared to be more effective compared to the crisis of 2008-2009. This is evidenced by data on changes in GDP PPP, indicating the best positive dynamics when exiting the recession during the pandemic. However, in both cases, significant devaluation was observed. In order to determine the causes and consequences of the depreciation of the national currency in relation to the US dollar and other currencies, an analysis of the balance of payments accounts was carried out by individual articles. This made it possible to indicate significant differences in the nature of the origin of these crises. The instruments of motto policy were also used with varying degrees of activity and in the opposite direction. Foreign exchange interventions in 2008-2009, in contrast to the period of 2019-2020, were used very limitedly due to the rather rapid depletion of gold and foreign exchange reserves. Foreign exchange restrictions were strengthened in 2008-2009, and liberalized in 2019-2020. As a result, it allowed to revive investment flows and improve the business climate in the country. It is also noted that against the background of general devaluation during both crises, a period of revaluation of the national currency was also observed in 2019. The analysis showed that in that case it was rather a negative phenomenon, which led to significant losses in the revenue part of the budget due to a decrease in revenues from customs payments, resulted from the inconsistent actions of the NBU and relevant ministries. Other elements of foreign exchange policy were almost not used: the degree of currency convertibility and the exchange rate regime did not change (with the exception of a short period of introduction of the exchange rate band).

Agricultural lands are an indispensable resource for ensuring food security in Ukraine. Ukraine is on the path of reforming land relations and forming a market for agricultural land. Since Poland is close to Ukraine in terms of climatic conditions and land use, its experience had been taken into account. The purpose of the article is to form the process of the agricultural land market in Ukraine based on the experience of Poland. To study the research problems, comparative methods of research and observation have been used, as well as methods of synthesis, analysis and abstract logical approaches to the search, justification and determination of periods of development of land relations in Ukraine and Poland. The article discusses the approaches of scientists to determining the essence of the “land market”, outlines the conditions for the development of the land market in European countries (Holland, Switzerland, Austria, Germany, Great Britain, Scotland, Spain, Poland, Bulgaria, Romania, Croatia, and Estonia). The periods of development of the land market in Poland and Ukraine have been highlighted. An analytical assessment of the market for the purchase and sale of agricultural land in the regions of Ukraine has been carried out (indicating the number of transactions completed and the total area of land plots). Comparative information on the cost of land in the European Union countries has been provided. The authors’ vision of the process of forming the agricultural land market in Ukraine is summarized, highlighting: I - Legal regulation; II - The step-by-step process of implementing the reform in accordance with the legislative framework, features of the implementation of land reform under martial law; III - Implementation of the land market using a transparent system through the Application (Unified portal of public services) Action; VI – State control over available agricultural lands and their legal structure; V – Conducting an expert assessment of land plots and/or determining their regulatory assessment; VI – State control over available agricultural lands and their legal structure; VII - Constant monitoring of the functional use of agricultural land.
