The following article is devoted to the theoretical analysis of the knowledge of the country’s world in the implementation of the program of the new war economy. The historical component can be seen in two directions – like a development of the war Europe, and the programs of international assistance to the Asian countries – Japan, Korea, Singapore. The current state of the economy of Ukraine was updated, internal and external remarks were seen, and the stages of the process of re-establishing the national economy were systematized. Potentially possible financial and institutional supply of resources and coordinating structures for the renewal of the economy of Ukraine was seen. Looking at the unique minds of geopolitical and socio-economic nature, in which our country was accused of the beginning of a military conflict, it was stated that the need for insane and uninterrupted participation of Ukraine in the preparation and promotion of international economic development. A wide retrospective analysis of the past analysis of international assistance programs for the countries of Europe (Marshall Plan), France and Great Britain, Ireland, as well as Japan (Dodge Plan), military renewal programs for Korea, Singapore, Hong Kong was carried out. The key factors for the success of the analysis of the countries in the reach of turbulent economic success are christened, their particular sectoral identity is stated by the obvious minds in Ukraine. It has been shown that the stencil for the creation of a new national model of economic innovation can be complex and revenge for the adaptation of foreign applications. It is recommended the author’s systematization of the principles of the implementation of international assistance programs that will be effective for the war economy of Ukraine. On the basis of them, it was formulated and in detail the transfer of direct reform of the economy of Ukraine with the improvement of stages and international access. Keywords post-war development, experience of international aid, Marshall Plan, Dodge Plan, “Asian economic tigers”, directions of economic recovery.

Consolidation with European social, economic and environmental programmes in the framework of Ukraine’s integration into the European energy space has become extremely important given the growing threats to energy security and should become the basis for greening regional and national innovation systems in the context of decarbonisation, the minimisation of carbon emissions and the transition to alternative energy sources. The comparison of the regions of the country by the level of enterprise innovation and the extrapolation of these results to the share of such enterprises in the total number of industrial entities in the regions helped identify their lack of correlation and emphasised the lack of stable dependence between industrial development and innovation activity. The methodology of the article includes a number of general scientific, special and interdisciplinary methods that allowed the screening of areas for the most favourable economic development, taking into account the synergistic component of regional development and achieving the research goal. The aim of this article is to analyse the innovative component of regional and national economic development for the implementation of decarbonisation and green energy transition in Ukraine, as well as substantiate the world’s leading imperatives and national directions for effective integration into relevant European programmes. An analysis of Ukraine’s rating status in several international indices of environmental efficiency and innovation activity in the regions showed the lack of correlation between regions of Ukraine, which actualises the search for the most effective drivers of economic development. At the same time, the consolidation of efforts of national stakeholders of innovative development in a country with relevant European institutions, particularly in the direction of greening regional economic systems, will ensure the development of innovative regions and industries, which will in turn be drivers of related territories and industries while ensuring a synergistic effect.

The aim of the article is to consider current global and European trends in ensuring a sufficient level of energy efficiency, to provide an analysis of the institutional environment for energy security, and the development and justification of a conceptual and analytical model of energy...

Purpose. The aim of the article is to analyze the theoretical-and-methodological and organizational-and-economic principles of modern development of Ukraine, burdened by military action, and provide practical recommendations for basic trends in sectoral development of postwar national economy, taking into account financial, industrial and organizational factors. Results. The article contains the results of an in-depth analysis of the preconditions and factors of renovation transformations of the Ukrainian economy. Econometric research methods, in particular, simulative modeling and cluster analysis, proved that for Ukraine in the postwar period, the most effective way to develop a destroyed economy will be the development of innovation-active regions and industries, which in turn will be drivers of related territories and industries, while providing a synergistic effect. Sectoral development should be based on the principles of Industry 4.0 and budget decentralization. A comparative analysis of the identity of the administrative system of Ukraine and Poland allowed us to offer our own vision of building a national system of budget and tax distribution with the introduction of fundamentally new institutions and mechanisms. Based on current global trends regarding the Green Deal, the transition to a low-carbon economy and decarbonization, as well as, taking into account the actual integration of Ukrainian and European energy systems, formulated directions for reforming the industry in decentralization reform. The influence of state regulation on the process of regional decarbonization is determined, based on the author’s analysis of the advantages and disadvantages of decarbonization models, the need for an integrated approach and the use of hybrid models in the postwar economic recovery. Applied models of decarbonisation of energy-intensive sectors are demonstrated, the model of structure of generation and consumption at lower levels according to the NUTS classification (Nomenclature of territorial units for statistics) is proposed for use, it has a double factor of energy efficiency. In order to legally regulate the regulatory framework and institutional environment, increase the effectiveness of energy efficiency policies of communities and ensure energy security of the state, a number of proposals for legislative initiatives. Scientific novelty. The scientific novelty of the obtained results is the study of theoretical and methodological foundations of postwar renovation of Ukraine’s economy based on sectoral development of innovation-active regions and industries, the principles of Industry 4.0, modernized budget decentralization. A mathematically formalized conceptual model of electricity generation and consumption at the local level is proposed. A comparative analysis of decarbonisation models conducted in the article made it possible to develop a hybrid integrated approach that would combine existing models and have a national orientation, taking into account the force majeure circumstances of the recovery of Ukraine’s war-torn economy. The dualistic nature of decentralization at the local level has justified the mechanism for financing regional energy management activities. Practical value. Theoretical and methodological achievements of the study became the basis for the formalization of tools and measures of transformation of Ukraine’s economy. The sectoral results of the research were used by the authorities and local self-government bodies at the regional (Regional Entrepreneurship Support Funds) and local levels (Mariupol District Council). The obtained practical results on sectoral development and budget decentralization can be used by central and regional executive bodies, sectoral enterprises in the formation of directions and mechanisms of postwar transformation of Ukraine’s economy.

This article is devoted to an analytical review of the situation in the energy sector of Ukraine, taking into account constructive changes in the connection of the Ukrainian energy system to ENTSO-E and the destructive situation caused by industrial infrastructure failures and economic renewal....

Digitalization of all spheres of life, from the business sector to public administration, has now become a common trend in the development of Ukrainian society, one of the main drivers of the socio-economic development of the country. The purpose of the article is to substantiate the feasibility of the cluster approach to the digitalization of public administration in the regional strategy, taking into account international best practices. Methodology. The theoretical and methodological basis of the study are the provisions of institutional theory, in particular, the paradigm of evolutionary development, digital economy, regional economy, clustering theory, the concept of strategic management, decentralization, public administration. In the process of research the following general scientific methods were used: analysis and synthesis (for the analysis of scientific schools of development of cluster theories, generalization of existing theoretical approaches and provisions, scientific developments on public administration, regional strategy, management of cluster development and clarification of terminological apparatus); classification and systematic approach (identification of industry specifics of cluster structures development in different countries; determination of peculiarities of IT-clusters creation on the basis of analysis of regional development strategies); comparison and structural-logical generalization (determination of peculiarities of international practice of cluster development and possibilities of its use in Ukraine; elaboration of a number of measures on formation of regional infrastructure of digital electronic administrative services). Results. The study revealed the sectoral focus of cluster structures in European countries. The features of the implementation of cluster policy and the key objectives of support for the development of cluster structures in a number of EU countries were identified. It is proved that the clusterization of the national economy, cluster policies and initiatives in the last decade have become important elements of strategies and concepts of innovative and sustainable development of European countries. Based on the analysis and synthesis of sectoral trends in the creation of cluster structures in European countries, it was found that the national characteristics of existing cluster policy determine the direction of cluster initiatives; strategic cluster alternatives are determined by national characteristics and the adopted cluster concept; to assess the feasibility of the cluster strategy of development of the territory it is necessary to correlate the level of investment potential and investment activity; methodological principles of formation of a national cluster strategy need to be refined and clarified, taking into account the current challenges. Practical implications. Based on the generalization of best international practices, it was found that to increase the competitiveness of the regional economy it is necessary to create cluster structures in the IT industry as an effective form of partnership. However, the study showed that the current legislation of Ukraine does not pay proper attention to the formation and functioning of clusters, including in the IT sector. To this end, it is necessary to make changes and additions to the Concept of creating clusters in Ukraine, the Regional Development Strategy until 2027 and action plans for their implementation in 2021-2023 years to create cluster structures as a business entity. It is advisable to develop and approve the Concept of Cluster Policy and the Target Program "The formation and development of clusters in the regions of Ukraine for 2021-2023 years", which should provide for the creation of IT-clusters as a special type of associations of enterprises in different fields, taking into account regional specificity. Value/originality. Author's approach to improving the legislative framework for the development of IT clusters in the regions of Ukraine, taking into account international best practices.
