In the world there no country, market or economy which is separated, and interconnection is becoming a fundamental feature of almost all social and economic systems. In the case of digital assets, such as cryptocurrencies, the impact of the relationship on their performance and price trajectory increases. The investigation of these phenomena is important for understanding the processes that govern cryptocurrencies. The objective of this paper is to assess the tightness of the relationship between the world's leading cryptocurrencies. In order to achieve this goal, the concepts of «cryptocurrency» and «blockchain», their history and features are considered. The principles of the first cryptocurrency – Bitcoin – are studied and the dynamics of changes in its price from 2015 to 2021 are analyzed. The price of Ethereum, XRP and major financial assets is compared. The best 20 cryptocurrencies at a certain time are identified with their price, capitalization and value changes over the last day and week. Based on the data from the Hackernoon website, research by Larry Chermak and the cryptocurrency publication The Block, it is determined that the strongest cryptocurrencies are interdependent or follow the most important cryptocurrency – bitcoin. Pearson's coefficient is considered. On its basis the correlation strength between eleven leading cryptocurrencies is determined, the part of the data are presented as a confidence interval. It is found that Ethereum and Litecoin have the strongest association with Bitcoin. Coin, Tron, Cardano, Bitcoin Cash, however, have low (negative) correlation between Tether or USDC. The main factors influencing the price of cryptocurrency are identified. It is also determined that alternative cryptocurrencies have lower correlation with bitcoin during periods of price growth, although the differences are not large, and during price decline the strength of bitcoin's correlation with other cryptocurrencies increases significantly, in most cases it reaches even very strong connection. The influence of social networks such as Google+ and Twitter on the price of cryptocurrency is determined as well. The proposed analysis makes it possible to understand the dynamics of cryptocurrency markets and the various processes that affect their efficiency.

The public finance sector plays a special role in the functioning of the financial system. A significant part of the funds is accumulated and redistributed through state and local budgets. At the same time, the formation of budget expenditures of all levels, their structure, determine the state and opportunities for the state to perform its functions, which is manifested through the structure of budget expenditures according to functional classification, as well as the distribution of funds to ensure current needs and capital expenditures, and its social orientation - through the structure of expenditures for economic classification. At the same time, the state of formation of budget expenditures at different levels is characterized by structural imbalance, so the article evaluates the formation of state, local, and consolidated budget expenditures according to economic and functional classification. The method of structural-dynamic analysis was used during the research and integral coefficients were calculated - linear and quadratic coefficients of structural shifts, integral coefficients of Gatev and Salai, which made it possible to substantiate the state of unbalanced budget expenditures of all levels. For the study, the period from 2015 to 2021 was taken on a quarterly basis, separately according to the expenses of the economic classification and according to the expenses of the functional classification of the state, local and consolidated budgets of Ukraine. In contrast to existing approaches, this study takes into account the peculiarities of the formation of expenses, which are associated with their quarterly fluctuations. It is substantiated that the structure of expenditures according to the economic classification of state and local budgets is unstable. The calculation of integral coefficients made it possible to draw a conclusion about the significant intensity of structural shifts, which indicates the absence of a consistent budget policy, since it, in turn, is based on the consistency of the economic policy implemented in Ukraine. The imbalance of expenditures by functional purpose, compared to the structural imbalance of expenditures by economic classification, is much smaller. The obtained indicators proved the process of redistribution of cash flows between budget levels as a result of reforms in Ukraine, related to decentralization and redistribution of powers between the national and local levels.

In Ukraine, the coronavirus disease (COVID-19) pandemic partially overlapped in time with such critically important transformational processes as the second stage of the financial decentralization reform and the integration stage of the health care system reform. In this regard, the study of the main peculiarities of the change in the model of financial support of the health care system in Ukraine in these conditions, as well as the determination of which of these processes had the greatest impact on the volatility of the health care public expenditures, becomes relevant. The research involves the implementation of two stages - bibliometric analysis and statistical analysis. According to the results of the bibliometric analysis of Scopus publications concerning financial support of the health care system and COVID-19, six contextual clusters of scientific research were identified, focused on determining the impact of health care expenditures on the effectiveness of anti-coronavirus measures, age, gender, social and medical prerequisites and consequences of the spread of the COVID-19, relationship between the cost of medical services and outpatient treatment, socioeconomic, financial-economic and institutional prerequisites for ensuring the quality of the health care system and its resistance to shocks caused by the pandemic, key determinants, tools and measures to combat the spread of COVID-19. As part of the second block of bibliometric analysis, aimed at identifying the relationship between health care expenditures and decentralization reforms, five contextual clusters are identified, which are focused on the study of approaches and models to optimize health care expenditures taking into account socio-demographic factors and decentralization reform priorities, fiscal, economic and ecological determinants and factors of public health, age and geographical prerequisites that determine the peculiarities of the formation of the health care financing system, the influence of micro-financial and managerial prerequisites for financial assurance of the quality of the health care system I, effectiveness of insurance medicine. According to the results of the statistical analysis, it is established that during the period of active implementation of the financial decentralization reform (2015-2018), the share of health care expenditures in the State Budget of Ukraine was relatively stable and fluctuated within 2%, while in 2019 the share of this group of expenditures has been increased to the level of almost 3.6%. At the same time, there was a reduction in health care expenditures in the expenditures of local budgets of Ukraine: during 2015-2019, their share gradually decreased by 3-5% annually, and in 2020-2021, the reduction amounted to almost 33% and 45% to the level the previous year respectively. The specific weight of this group of expenditures in the Consolidated Budget of Ukraine is relatively stable (9–11.1%). In general, according to the results of the analysis, it can be noted that the reform of financial decentralization did not lead to a significant transformation of the structure of spending powers, while the medical reform and the COVID-19 pandemic caused a redistribution of the expenditure burden in the field of health care from the local to the state budget, although the specific weight of these expenses in the structure of the Consolidated Budget of Ukraine did not increase significantly even during the pandemic period.

The article is aimed at studying the evolution of money. The article examines the history of the emergence and evolutionary development of money and cryptocurrencies. Blockchain technology is analyzed, as well as the technological difference between Bitcoin, Ethereum, Solana cryptocurrencies is considered. The issues of the operation of the Ethereum blockchain and smart contracts are covered. An analysis of blockchain technology and the use of cryptocurrencies as a means of payment is carried out. The type of cryptocurrency such as a stablecoin is revealed in its variety. Comparisons of native blockchain coins and stablecoins as a means of payment, further of USDC and USDT stablecoins, are made. An analysis of differences between the centralized and decentralized stablecoins is carried out. It is specified what the stablecoins USDC, USDT, DAI are backed by. It is analyzed what share of the market is occupied by USDT, USDC, and DAI. The advantages and disadvantages of stablecoins are identified. A characterization of activity of the Central Bank Digital Currency (CBDC) with its connection to central banks is presented. It is determined that stablecoins are an attempt to objectively eliminate the high volatility of traditional cryptocurrencies such as Bitcoin or Ethereum by tying the value of a stablecoin to one or more other assets, such as fiat currency. Blockchain technology along with stablecoins can increase the efficiency of cross-border payments. With the growing demand for use, a stablecoin can become one of the important elements of the payment infrastructure. As result of the study, a comparison between cryptocurrencies and the companies Visa, Paypal in terms of processing speed and the amount of payment commissions is made. It is determined that blockchain and cryptocurrency technologies are a new evolutionary stage in the development of money. It is substantiated that the effect of using blockchain technology allows to cheaper and faster money transfers. It is noted that blockchain technology is young, but cooperation between traditional financial companies and cryptocurrencies is already visible.

The completion of the decentralization of authority and finance in Ukraine has opened up new horizons for the creation of innovative approaches to territorial community management. Local governments were granted significant powers and financial resources, which creates new opportunities for the development and expansion of the capacity of communities. The rights of local governments in the organization of community management were expanded, which contributes to a more effective and balanced solution to local problems. Thus, the management of competitive advantages of territories is an important topic in economics, management, and regional development. The study of this issue is becoming increasingly relevant as more and more regions around the world compete to attract investment, develop entrepreneurship and tourism, develop transportation infrastructure, create jobs, and improve the quality of life. The article aims to examine new approaches to the development and management of competitive advantages of territories based on foreign experience. The article analyzes the peculiarities of competitive advantage management in local communities of several EU countries. Based on the study, the authors identify and substantiate the advantages of foreign experience and reveal the shortcomings that should be taken into account when implementing this experience. The author substantiates the process of decentralization reform and its impact on the development of territorial communities in terms of the use of management tools to increase the competitiveness of territories. The article shows that clustering, strategic planning, and public-private partnerships are the main tools for improving the competitiveness of communities. The main directions used by a number of countries to improve the efficiency of territorial development are characterized.

Introduction. The change of the administrative-territorial system at the basic level and the reform of the public administration system in Ukraine in 2014–2020 took place on the basis of the experience of the EU countries regarding the decentralization of administrative and financial powers in favor of local self-government. Today, the first stage of reform has already been completed, because territorial communities as the basic units of the administrative-territorial system have been formed throughout the territory of Ukraine, as well as redistribution of spending powers and revenue sources between different levels of management. Accordingly, the issue of ensuring financial self-sufficiency of territorial communities for the long term is being updated. Decentralization in European countries took place in different periods, and therefore, the tasks that today face the Ukrainian state and local self-government in particular, these countries have already solved with one or another measure of efficiency, which makes it possible to talk about the possibility of adapting the acquired experience to domestic realities. The purpose of the article is to study European practices of ensuring financial self-sufficiency of basic administrative and territorial formations for the further implementation of the most effective practices in domestic realities. Results. The practice of developing the public finance system on the basis of decentralization in the EU countries was studied, the difference between the levels of decentralization of territorial communities in different countries and the tendency to exceed the level of decentralization of expenses over the level of income decentralization was revealed. Emphasis is placed on the key principles of ensuring financial self-sufficiency of territorial communities in the European Charter of Local Self-Government. The existence of a financial "cushion" for territorial communities in the form of distributed resources from supranational funds is substantiated. Given the lack of such a mechanism in Ukraine, the need to study European practices for accumulating sufficient financial resources for community development is argued, including taxes on economic activity (personal income tax, corporate income tax, local business tax, property taxes on commercial real estate and land) and local borrowing.

Introduction. Economic development of Ukraine in the third decade of the 21st century largely depends on the development of digital technologies, on which the cryptocurrency business directly depends. According to the Index proposed by chainalysis.com, Ukraine is one of the leaders in the world and the undisputed leader in Europe in the adoption of cryptocurrencies. This became possible thanks to the active development of financial and information technologies in Ukraine, and the financial, economic and military-political crises only give additional impetus to the development of the cryptocurrency business due to its global nature and full or indirect independence from attempts at state regulation. One of the areas of cryptocurrency business development is cryptocurrency mining. The purpose of the article is to reveal the algorithm of conducting business in the field of cryptocurrency mining and the economic efficiency of mining in Ukraine and the possibility of its impact on economic growth in the country. Results. Cryptocurrency mining is the process of creating cryptocurrency coins. It has been investigated that the cryptocurrency mining process is not a financial pyramid or some kind of virtual game, but is one of the newest types of business activity, which requires significant theoretical and practical economic and technical knowledge, is economically expedient both in the short and long term. When mining, you can use a variety of computer equipment, depending on the miner’s economic tasks and desired results. ASIC equipment has been developed for mining on an industrial scale. Cloud mining is used for investing. If there is no knowledge about mining and limited financial resources, you should use browser mining or mine on your own PC, laptop or smartphone. However, the most efficient and widespread mining takes place on video cards. It was found to be a by-product of mining. It is estimated that there is a slight correlation between the earnings of miners on the Ethermine mining pool and the daily mining profit. Conclusions. Although the history of cryptocurrency business is only one and a half decades, mining, as an object of business activity in Ukraine, is a significant economically effective type of business activity, which is noted in the world rating of the perception of cryptocurrencies, according to which Ukraine is one of the world leaders. Attempts to implement legal regulation of cryptocurrency mining both in Ukraine and in other countries, and its gradual implementation do not significantly harm the creation, distribution and use of cryptocurrency coins, however, will create transformed conditions for the economic attractiveness of cryptocurrency mining as business objects.

The article considers theoretical and practical aspects of financing general secondary education in Ukraine and the European Union member states, in particular in Finland, Estonia and Germany. Studies of Ukrainian and foreign researchers on the problems of the decentralization of secondary education management, expanding the autonomy of education authorities at the local level, and establishing the rights and responsibilities of the institutions both in educational processes and in financial support were analyzed. The article justifies the importance of implementation of the reform of decentralization in Ukraine, as a result of which the rights of local self-government bodies in making managerial decisions, in particular in the system of financial resources and control, have been expanded. Analytical indicators of the efficiency of the use of funds of educational subsidies allocated for payment of salaries of teaching staff in 2021 are provided, and the relationship between the cost of education per student and the number of classes in the general secondary education institutions is established. The example of the rural territorial communities helped to prove that the larger the number of classes in the general secondary schools, the lower the cost of education per student. The most common factors of mismanagement and misuse of public and local budgets were identified, in particular the lack of sound forecasting and planning; the misuse of financial resources; unreasonable management decisions; long-term maintenance of the balances of educational subvention funds without the use of the accounts of budget fund managers and the current accounts of educational institutions, etc. The planned amounts of the educational subvention and the subvention for the provision of support for persons with special educational needs for 2022, as well as the remaining unused funds under these subventions, were analyzed in detail. The volumes of the sequestration of subventions, which took place as a result of the military aggression of the russian federation against Ukraine are given. Further research will include the systematization and development of financial reporting forms for a comprehensive analysis of the use of financial resources at all levels of school education management.

The cryptocurrency market has been developing dynamically in recent years. The rapid development of the market is the result of an increased interest in cryptocurrencies, both from those who consider it as a means of payment, and from investors who purchase cryptocurrencies for speculative purposes. Blockchain technology, on which cryptocurrencies are based, has gained acceptance in the financial industry, and many companies are engaged in the work on using it in their activities. On the other hand, numerous supervisory authorities, including the European Banking Authority, the European Central Bank, the National Bank of Poland and the Polish Financial Supervisory Authority, warn against investing in cryptocurrencies, pointing out the numerous risks associated with such investments. The purpose of the article is to analyze the benefits and potential risks of investing in cryptocurrencies. The object of the research is investing in cryptocurrencies. The subject of the research is cryptocurrencies as investment. The author used the methods of analysis, synthesis, generalization and deduction. As a result of the study, the advantages and potential risks of investing in cryptocurrencies were analyzed. In addition, countries that have fixed the management of the bitcoin cryptocurrency at the legislative level have been reviewed.

The article is to research the possibilities and prospects of using graphical technical analysis for forecasting the movement of asset prices by an Internet trader using the example of Bitcoin (BTC – BitCoin). The theoretical and methodological aspects of cryptocurrency technical analysis in the conditions of modern financial markets were analyzed. A comparative analysis of short- and medium-term technical analysis strategies in Internet trading was carried out. Cryptocurrency-applied technical analysis was used to determine current trends of the Bitcoin growth cycle. The research methods included comparative analysis, and graphical and analytical methods of technical analysis such as the method of observing price movement, capitalization analysis, pattern identification, support/resistance levels identification, indicators use and comparison, and bars analysis (Japanese candles). Cryptocurrency analysis used the Traidingview platform data from BINANCE, BITSTAMP and CRYPTOCAP exchanges. Considering the example of the analysis of the medium-term agreement with patterns and indicators of the BTC instrument, the most likely movement of the asset price is calculated in several stages. In the first stage, the classification of analysis tools and the possibility of applying several of them were investigated. The second stage involved analyzing the difference and risk of using different time frames for investment and finding rational ways of applying the available information to analyze the subsequent deal. In the third stage, a comparative analysis of the transaction with the BTC instrument was carried out, and the likely movement of the cryptocurrency price was determined. Based on the research, the only possible scenario for the behavior of the BTC instrument has been developed, namely: a drop in price and accumulation in the further bearish market. It is substantiated that the best option for analysis is the collection of all available information from the chart and its further analytical summation to obtain the most likely trend of the instrument's movement, as well as the analysis of the speculative value of the deal. The considered approaches to the technical analysis of the Bitcoin cycle create a scientifically based practical tool for Internet trading.

Introduction. The decentralization processes have updated the need to solve two interdependent tasks: to substantiate the role of local governments in meeting the needs of the population and thus determine public goods that have to be secured at the level of territorial communities, regions, and the country and sources of financial resources for their provision; to outline the ways of territorial communities’ development in a long run and achievement of their self-sufficiency as an efficiency criterion of administrative-territorial reform. For that matter, the substantiation of theoretical foundations of territorial communities’ self-sufficiency is an important scientific task. The purpose of the article is to substantiate the theoretical foundations of territorial communities’ financial self-sufficiency and determine its place in the structure of communities’ self-sufficiency. Methods. The methods of dialectical analysis, synthesis, and logical generalization, as well as comparison and formalization, were used in the research. Results. The nature of the territorial community concept is defined and its economic features are outlined. The theoretical foundations of territorial communities’ financial self-sufficiency are examined and on this basis, the definition is interpreted considering the interrelated concepts of socio-economic systems’ self-sufficiency and territorial communities’ self-sufficiency. A territorial community is financially self-sufficient if its financial system is characterized by self-reliance in conditions of vertical integration into the system of public finance, and if it is capable to maintain and/or improve the achieved development level and secure normativity of providing social goods to the population due to efficient use of financial tools under the impact of external and internal factors. The paper emphasized the role of vertical integration of the community’s financial system with the system of public finance and the top priority of internal capacity to develop in the community for achievement of financial self-sufficiency. It also substantiates the need to determine the normativity of public goods provision to the population in the process of the use of financial tools.

The author analyzes the existing legal regulation of relations related to the use, issuance, trade and other operations with cryptocurrencies in the European Union law. It was noted that the development of cryptocurrency markets in the EU requires a well-built legal framework clearly defining the regulation regime for all cryptocurrencies that are not subject to current legislation on financial services. The main directions of regulatory influence on the cryptocurrency market in some EU Member States are identified. The problems of the system of legal acts covering legal relations with cryptocurrencies are analyzed. It was stated that creating a high-quality and effective legal framework within the EU internal market is an extremely important though challenging task. Perspective directions of legal regulation of crypto-assets according to the Proposal for a Regulation of the European Parliament and of the Council on Markets in Crypto-assets, and amending Directive (EU) 2019/1937, COM/2020/593 final, are analyzed. When analyzing the draft Regulation, it was found that its adoption would be an important step towards maximum harmonization of cryptocurrency legislation. A number of problems of the future legal act have been revealed. These include ambiguous legal regulation of cryptocurrency market participants’ cybersecurity. In addition, the legislative bodies should bear in mind that cryptocurrencies are in the process of constant transformation and transition from one type of token to another. In this case, the rules of the upcoming Regulation should be more flexible to future changes. It was concluded that according to the current draft Regulation, it is extremely unlikely that any types of crypto-assets will remain unregulated in the EU.

The territorial organization of the state plays a key role in ensuring optimal solutions to the problems and functions of society and the state. Most modern countries differ in their internal organizational structure, i.e. the method of territorial division, the number of administrative-territorial units, autonomous units, their authorities, the method of formation, as well as the degree of centralization (decentralization) of state power. The organization of public power, stability of inter-government relations, ensuring sustainable development, meeting the needs and interests of the population depend on the administrative-territorial structure 1 . The Constitution of Ukraine defines the basic principles of the territorial structure of Ukraine, the system of administrative-territorial units of our country, taking into account economic, historical, geographical, environmental, demographic characteristics, ethnic and cultural traditions. However, since the declaration of independence of Ukraine, discussions have begun on the need to reform the existing administrative-territorial structure 2 . Attempts to implement constitutional, administrative, municipal, and other reforms in Ukraine have not yet led to successful results in this area. This issue is important in the current situation when the search for the optimal model of the administrative-territorial structure of Ukraine is being carried out. History shows that destructive trends in countries are a consequence of the lack of a balanced management system, its territorial organization, primarily a balanced administrative-territorial division, and the status of administrative-territorial units 3 . Optimally organized geographically and

Reform of fiscal decentralization is one of the most effective modern tools to improve the efficiency of public and local finances, as it involves the transfer of some powers from central to sub-central governments according to the principle of subsidiarity.Therefore, one of the top priorities in public finance development nowadays is to ensure municipal financial resilience (financial capacity).In the paper it is proposed to measure municipal financial resilience (financial capacity) as an integral indicator of fifth parameters (ratio of revenue / cost / tax revenue of local budgets (excluding transfers) to revenue / cost / tax revenue of the consolidated budget, "1" reduced by the ratio of net intergovernmental transfers to own revenue of local budgets; ratio of own revenue of local budgets to their own expenditure) aggregated based on Fishburn formula.It is proposed to chose as a proxies of municipal sustainable economic development such indicators as consumer price index, current account balance, volume of credits to the private sector, net foreign direct investment, GDP growth, GDP per capita, gross capital formation, business density, employment ratio, R&D expenditures, trade turnover.Testing the hypothesis on relationship between municipal financial resilience (financial capacity) and its economic development is realized on data for Ukraine for the period 2008-2021.Method of modellingregression analysis in Stata software.Based on the empirical research results it might be concluded that there are national peculiarities of relationship between municipal financial resilience (financial capacity) and its sustainable economic development in Ukraine, which might be considered in terms of fiscal decentralization reform implementation, counteraction to negative consequence of coronavirus disease pandemic and municipality post-pandemic recovery strategy.

The paper notes that at the present stage, research primarily by foreign scientists defines decentralized finance as based on the cryptocurrency ecosystem. The development of new financial technologies, which led to the emergence of digital currency, and its attractiveness, primarily as an asset for investment, have already formed a certain ecosystem of cryptocurrencies. In particular, the functioning of crypto-exchanges, which include various participants: issuers providing mining, agents and a kind of intermediaries in cryptocurrency transactions during the circulation of stablecoins. The dynamics of market capitalization of cryptoassets was analyzed according to the statistics of the International Monetary Fund (IMF), which increased more than 10.5 times (from USD 191.6 bln at the beginning of 2020 to USD 2,027.5 bln as of the end of September 2021). At the same time, it should be noted that the structure of the cryptocurrency market is unstable, which is typical for the new market that is in its infancy. This is confirmed by the market capitalization structure of bitcoin, ethereum, and stablecoins for the above period. Based on IMF data, indicators characterizing the state of formation of the cryptocurrency ecosystem, namely, bitcoin volatility and market capitalization of tokens, are analyzed. It is noted that the fairly rapid spread in the global financial space, and especially the growing attractiveness of cryptocurrencies in emerging financial markets, require the study of possible risks, arising from the formation of an ecosystem of cryptocurrencies and decentralized finance to ensure the stability of the centralized financial system. The main financial stability risks associated with the cryptocurrency ecosystem are systematized and grouped into key blocks: operational risk, cyber risk, misappropriation, bribery and corruption, as well as risks related to financial imbalances. The emphasis is on a problem that is formed purely in the field of decentralized finance and is associated with the development of peer-to-peer lending, crowdfunding and crowdinvesting. A generalization is made about the understanding of the ecosystem in the financial system (financial ecosystem), which is used in modern research at two levels: at the micro level it reflects the business model of a financial institution, and at the macro level it reflects the transformation of the financial system under the influence of financial technology. The formation of the financial ecosystem was the result of the intensive development of financial technologies (FinTech), among which neobanks are the most popular today. In addition, a classification of neobanks is proposed with an emphasis on the level of digitalization.

With the development of financial institutions, this application software and related information technologies are used not only by specialists, but also by ordinary citizens to solve tasks that a few years ago seemed to be within the competence of only mathematicians specializing, for example, in building forecasting models. It can be noted that the collaboration of IT with application software, as well as with the mathematical apparatus most typical for forecasting tasks, gives good results. In particular, this applies to the Central Bank market. The study is devoted to the problem of approaches to the selection of methods and strategies for analysis and forecasting of the central bank markets, which is an urgent issue today. Far from all possible methods and strategies have sufficient coverage in the scientific information space, which prompts the need to analyze and systematize already existing information in this field. Accordingly, basically. the purpose of the study is to analyze and systematize the theoretical foundations of existing approaches to forecasting the CCV market. An analysis and systematization of the theoretical foundations of existing approaches to forecasting the CCV market was carried out. Generalized advantages and disadvantages of structural methods and models used for making market forecasts were outlined. A comparative analysis of ANN models was carried out in terms of their use for market analysis tasks. Among the analyzed ANN models are the following: CNN-2l, CNN-3l, LSTM, sLSTM, BiLSTM, GRU, CLSTM, MLP and RFBNN. The analysis and testing of existing models provided results that provide a wide scope for further research and study.

The purpose of this article is to develop and substantiate a conceptual and analytical model of the structure of energy generation and consumption at the local level in the context of the decentralisation reform in Ukraine on the basis of an analysis of current world-wide and European trends as to ensuring a sufficient level of energy efficiency. The current trends of world energy consumption are illustrated, the forecast for the development of renewable energy is built, the energy efficiency analysis of the national economy is carried out. In order to form a holistic system of energy management on the local grounds, a model of generation and consumption for use at the local level is proposed, the financing of which is provided for by the results of the use of a comprehensive mechanism. A number of normative and organizational-institutional proposals on the normalization of energy efficiency improvement processes are suggested. The factors of energy efficiency of this model, financial instruments for its effective functioning in the form of a mechanism of interest-making budget revenues and specialized funds are disclosed; organizational and institutional support of such reform is proposed; the functional dependence of the target function of the model of energy generation and consumption is detailed, taking into account the methods of generation and the main consumers at the appropriate levels. The analysis of the main risks is carried out and the flaws of this process are defined; a number of regulatory and institutional transformations are proposed to improve the effectiveness of the implementation of an effective policy of energy efficiency of hromadas thus ensuring the energy security of the State. It is recognized as expedient to adopt a package of bills and resolutions on energy cooperation, organization of a biofuel exchange. The model of organization and functioning of a cooperative for the generation and consumption of solar energy, which is based on the regulatory framework, is presented. The above mentioned allowed to develop scientific and applied recommendations for improving regulatory provisions, which will enable the hromada to become an effective player in the wholesale electricity market, marketing the energy according to the green tariff.
