In the context of the digital economy development, the priority component of the economic security of an enterprise is changing from material to digital, constituting an independent element of enterprise security. The relevance of the present research is driven by the need to solve the issue of modernizing the economic security of the enterprise taking into account the new risks and opportunities of digitalization. The purpose of the academic paper lies in identifying the features of preventing internal and external negative influences (threats) in order to guarantee the effective and stable functioning and dynamic social development of the enterprise in the context of digitalization. The research methods are as follows: general scientific research methods, in particular, logical analysis, theoretical substantiation, methods of induction and deduction, formalization and generalization, statistical observation. Results. It has been proposed to introduce the concept of “digital security of the enterprise” for replacing the concept of “information component of economic security” in order to bring the terminology in line with new economic realities. The implementation of the “black box” model has made it possible to identify the latest risks and threats to the economic security of an enterprise within the conditions of the digitalization that differs from the existing ones. The assessment of enterprises’ digital security of the European Union member states has revealed that the digital security level does not depend on the size of the country, however, it is influenced by the institutional environment (in particular, digital development tools in the EU) and the size of enterprises. Also, within the research framework, an assessment of the digital security level of enterprises in the context of digitalization has been proposed. In order to characterize enterprises by the level of digital security, a calculation procedure using the coefficient method has been proposed.

The identity and institutional capabilities of the European Union (EU) have changed over the years. As a global player in international politics, the EU has recognized the need to develop a comprehensive space policy perspective. This perspective is shaped by changes in the dynamics of the space ecosystem, the "New Space", and this phenomenon consists of new business models, new technologies, new markets, new value chains and new actors. New space actors (private investors) have fundamentally changed the dynamics of space activities. The subject of the research is the peculiarities of the influence of investment processes of the EU and Ukraine on the development of space industries. The methodological basis consisted of general scientific and special methods of knowledge, based on a systematic approach to the consideration of economic processes. The article aims to examine investment in the context of space management in the EU and Ukraine, and to examine in detail the trends in such funding of space companies. In order to better understand the European space system. The article concludes that, recognizing the indisputable importance of space applications and safety of space systems, the EU attaches great importance to taking into account the trend of "New Space" in its governance structure and stimulating changes in this sector. Unfortunately, Ukraine lags far behind in this respect. In the EU, in the initial stages of space research and use, space programs are financed from the general budget, and as individual activities reach a level of profitability, their public funding is reduced. Therefore, the sphere of commercial space activities and the share of private investments in their total financing are rapidly growing. The reduction of state expenditures is compensated by investments of private business in commercial projects. Thus, the article emphasizes the particular importance of private investments in the development of the Ukrainian space industry and points to the need to develop the commercialization of space activities, especially given the potential in the absence of budget financing. It is impossible to compare the sufficiently powerful and effective investment system of the EU and the lack of even state financing of the space industry in Ukraine. Against the backdrop of hostilities in Ukraine, there is a significant need to reconsider investments in this area on the basis of public-private and international partnerships. Conclusion. The main tasks for Ukraine are revision and change of the state policy, right accents on investments into the space industry, qualitative overcoming of bureaucratic obstacles, approval of a new Strategy of Space Industry Development. As an example, one could use the experience of the EU and refer to its previous experience in this sphere to have an opportunity to stay among the world space powers.

Scientific sources demonstrate different attitudes of researchers to cryptocurrencies because they treat them as a category of currency, virtual money, commodity, etc. Accordingly, the relation to the valuation and risk of cryptocurrency as an investment object is different. The purpose of the article is to identify cryptocurrency value formation factors and determine the risks of investing in cryptocurrency. Cryptocurrency is simultaneously considered a currency, an asset with uncertain income, and a specific product, the price of which is determined by the energy costs for mining new cryptocurrency blocks. Thus, the paper examines the risks of investing in cryptocurrency from several positions. First, the study identifies the factors of formation of the value and risk of cryptocurrency as ordinary money based on comparing cryptocurrency with traditional money. Unlike traditional money, cryptocurrency is not tied to the economic performance of a particular country; also, central banks do not control or regulate their mining. Instead, the cryptocurrency emissions depend on the computational capacity of the equipment used for their mining. As a financial asset, cryptocurrency can be a “financial bubble” because their value increasing often exceeds the cost of mining. On the other hand, given the emergence of cryptocurrency as a phenomenon of the information economy, the paper analyses the impact of specific technical features (cryptographic hashing algorithm, the complexity of creating new blocks, the technology of verification of mining operations, etc.) on the risk of investing in cryptocurrency assets.

Bakery products are very important in human nutrition and are the basis of any daily diet. Their social significance is determined by the traditions and habits of the population of the countries, accessibility for all groups of the population, diverse assortment, including bakery products for functional and specialized purposes. The up-to-date trend is to expand the assortment of functional bakery products, the use of which will provide the body’s need for the necessary macro- and micronutrients for an active and healthy lifestyle. In the bread and bakery products market, consumer preferences are constantly changing. Consumers prefer products that contain less fat and sugar. The market is in demand for bakery products that are healthy, while taste remains an important success factor. Manufacturers include popular healthy additives (grains, seeds and legumes) in their products. Particularly popular at present are ingredients from Eastern Europe and Asia: yuzu, sesame, matcha, shiso. Tropical fruits (passion fruit, mango, bergamot) and fragrances (dried hibiscus, lavender and rose) are predicted to become popular. This causes the complexity of demand segmentation, features of merchandising and pricing policy, features of consumer behavior and consumption psychology, etc. An assessment is given of the dynamics of production and consumption of bread and exports of products, and a forecast is made for the development of the world market for bread and bakery products. The results of the analysis are necessary to assess the level of food safety and to develop a strategy that takes into account the current trends in the global bread and bakery products market. Prospective trends for sustainable production of frozen bakery products have been developed.

The article analyses the impact of the sanctions of civilized countries on the Russian economy. Particular attention is paid to sectoral sanctions on the markets of oil and oil products, in the banking and financial sectors, as well as on the market of transport services. The authors analysed the prospects for expanding sanctions on the oil market for Russia in the context of setting a maximum price for the export of Russian oil by the main buyers. Conclusions are drawn not only about the impact of sanctions on Russian oil production, but also about a possible decrease in prices for oil and other energy resources in the region. The authors positively assessed the US and EU anti-Russian sanctions in the financial sector. The impact of sanctions on the Russian banking system, insurance, and stock markets was studied. Particular attention was paid to the impact of disconnecting the banking system of the Russian Federation from the international payment system SWIFT. The authors also focused on the gradual division of the Russian economy under the influence of sanctions and trends in the energy market into the energy sector and the rest. It was found that the most affected by the sanctions were air transportation, mechanical engineering, and ferrous metallurgy sectors. Conclusions are drawn about the need to continue sanctions pressure on the Russian economy. High energy prices during the 200 days of the war with Ukraine allowed the Russian Federation to subsidize economic sectors that suffered from the war at the expense of the energy sector. A market reduction of the oil prices or their correction with the help of the sanctions policy should cause significant and irreversible damage to the Russian economy.

This paper studies the issue of financing the Space Industry at the State Level in the Postwar period as part of the country’s recovery plan, as one of the foremost critical zones of technological development and to ensure space security and defence. The European Space Agency (ESA) is, identified as the main player in the European space sector. It is determined that the current structure of ESA – Space 4.0 – provides for the success of European space activities in close coordination with the needs of European societies and economies. Despite all the prospects, offered by the Space Industry, a number of barriers can hinder full participation in the space economy. These ‘barriers’ include the requirement of large capital investments, technological risk and longer de-velopment times. Public-private partnerships have been, identified, as an effective way to overcome these barriers, so the government should play an important role in pro-moting innovation through the space sector. The war in Ukraine, which began on Feb-ruary 24, 2022, once again, reminds us of the unique value, and critical use of outer space for security and defence purposes. From intelligence gathering and monitoring to the availability of communications. It is determined that the war already has serious consequences for the European space sector. The Space Industry of Ukraine is a critical component of the national economy of Ukraine because it is the motor of numerous imaginative changes in other segments of the economy and contributes to the improve-ment of social, political, financial and natural circles of society. In Ukraine, there's an incessant disappointment in the State to fulfil its commitments to the ventures in the Space Industry. In the conditions of full-scale, ‘war’ the Space Industry isa key element of national security and defence of Ukraine. The financing of the Space Industry at the State level in the post-war period is crucial as part of the country’s recovery plan.

The article examines the peculiarities and modern specifics of the formation of ecological and economic security in Ukraine in the conditions of digitalization. It was determined that the lack of dynamic growth, the violation of the optimal balance and balance of the ecological and economic system are caused by the depletion of raw resources, a decrease in the overall potential of the environment, and the irrational use of natural resources. It has been proven that in the conditions of digitalization, a new challenge for all enterprises is to ensure the ecological and economic efficiency of their activities, which combines the principles of transparency and openness in their functioning. It has been proven that the strategy of environmentally-oriented economic development should be aimed at solving environmental problems and preserving biological diversity.

The article examines the peculiarities of the formation of the ecological and economic security system and the specifics of its principles. The relevance of the transformation of approaches to understanding the essence and principles of ecological and economic security in the context of the need to ensure sustainable development is substantiated. The levels of ecological and economic security and the peculiarities of changes in profits and costs during the transition of the economic system and business entities between these levels are determined. The principles of implementation and formation of economic tools for ensuring environmental safety are proposed.

The introduction of digital technologies in agricultural production is one of the most important elements of strategic development in the agricultural sector and rural areas in Ukraine. In agriculture, these new technologies can modernize the industry, promoting innovation in agribusiness and creating new opportunities for rural development. The introduction of digital technologies in agriculture ensures the accuracy of measurements, speed data collection and processing. Digitization in rural areas is an inevitable process that brings a number of economic, social and environmental benefits. The immediate aim of this paper is to assess the state of implementation of digital technologies in agriculture and to examine opportunities for rural development in Ukraine. Research methods: monographic, descriptive, analysis, synthesis, induction. The results indicate that only large agricultural enterprises in Ukraine are able to implement and use digital technologies. Thus, it is proposed to create an integrated digital portal for agricultural needs, combining solutions that optimize activities of agricultural enterprises: land bank management, production, crop monitoring, warehouse, procurement and supply, equipment and repairs, logistics, inventory and finished products. The article identifies technological and human barriers to introduction of digital technologies in rural areas of Ukraine. In addition it proposes strategies for development of digital literacy and skills among rural residents in Ukraine. The results of the research can have a significant impact on the development of agriculture in Ukraine, promoting digital technologies among other agricultural enterprises and ensuring the development in rural areas, attracting additional agricultural market participants and infrastructure that provide relevant information and digital services to rural residents.

The aim of the article is to develop the existing methodological approaches to assessing the military and economic capabilities of the country in conditions of war and peace. To achieve the purpose of the study, its decomposition was carried out and the following were investigated: existing approaches to assessing the military and economic potential of the country, the country's power and national power; the concept of critical load of the national economy is revealed; the generally accepted norms on financing of defense needs are resulted; the experience of financing the needs of defense by the leading countries of the world - in the conditions of the Second World War is given; a methodical approach to assessing the military and economic capabilities of the country is proposed.

The article considers the problem of ensuring the economic security of trade enterprises by forming an optimal pricing policy. The methodology of formation the minimum and maximum selling prices of trade enterprise, maintenance of margin of economic security, which is based on research of turnover costs and working capital of trade enterprise is offered. Based on statistical data of trade enterprises, the types of prices by product range are determined, which form a stable economic situation and ensure economic security of trade enterprise. The necessity of forming the optimal price policy and selling prices of trade enterprises with the use of Pareto efficiency tools and construction of single-criteria and multi-criteria tasks, indicators of quality of commodity resources of trade enterprises is substantiated. Using the Excel software processor and the «Regression» function, economic-mathematical models of optimal prices for the product range of trade enterprises are built. The results testified to the effectiveness of the proposed model of the optimal pricing policy of trade enterprises, as the obtained values are within the minimum selling prices, which provides economic security of trade enterprises. The process of forming the pricing policy of trade enterprises to ensure economic security is proposed, which is based on the principles of pricing, appropriate methodological tools and monitoring of market environment factors. Organizational, economic, legal, social and market (marketing) mechanisms for the formation of effective pricing policy of trade enterprises aimed at ensuring economic security are identified. This study is practically interesting for personnel of trade enterprises, regardless of organizationallegal forms of ownership and activities, and theoretically – for researchers dealing with pricing.

This paper considers the issue of state financial protectionism of the agricultural industry in the context of regionalization. A comprehensive methodology of state financial protectionism of the agricultural industry in the context of regionalization has been proposed, taking into consideration IPR and the value of the agricultural industry in a region. Based on statistical data on the indicators of investment attractiveness of the region (IAR) and the value of the agricultural industry in a region, regions for financing were determined. The problem of determining the fate of state financial protectionism for the agricultural industry in the context of regionalization has been stated and solved. The proposed methodology was tested by an experimental method. It is proposed that the state financial protectionism in the context of regionalization should include budget (investment) financial injections based on the investment attractiveness of a region and the value of the agricultural industry in the region, which are directed to the agricultural sector, in order to support it. The calculation results show that the distribution of financial resources with the available amount of public finances S=1 allocated for support is carried out proportionally. The comprehensive approach has made it possible to identify four regions for financing, and those are the regions that have the greatest value in the agricultural industry. Practical value is for management bodies (local, territorial, etc.) in the distribution of funds according to the vector of protectionism of the agricultural industry. The theoretical value is for researchers dealing with financial support, state protectionism, and public administration.
