The article examines the innovative trends in the renewable power generation, taking into account the impact of crises, as well as the impact of renewable energy on air pollution in the world (environmental change). Hierarchical agglomerative and iterative methods of cluster analysis, as well as econometric models were used to test the hypotheses. Carbon dioxide emissions and renewable power generation for 78 countries during 2000-2020 are taken into account as the database of the study. The results showed that there are groups of countries with sharp, high, moderate and low growth rates of renewable power generation. In addition, the results of econometric analysis indicate that the growth of renewable power generation does not always cause a decrease in carbon dioxide emissions. For a number of countries (Australia, Canada, Mexico, Poland) such connection is not essential at all. The results of the study can be useful in shaping and adapting environmental strategies around the world.

The importance of the study of the united territorial communities functioning and the identification of the main problems of organizational support of local budget management are substantiated. It has been studied that the issues related to the development of organizational support of local budget management are insufficiently researched in the domestic scientific literature. The paper clarifies that the decentralization of government should ensure the democratization of society, combine administrative, political, fiscal decentralization and involves the transformation of the interaction between governmental agencies and citizens, NGOs and businesses. The regulatory framework for the reform process is provided. Problems of united territorial communities development are identified. One of the first of them is the problem of proper implementation of the territorial community functions, which is intertwined with the filling of the UTC budget, the formation of financial resources sufficient to adequately finance the urgent social needs of communities based on the principle of subsidiarity, implementation of their economic and technological development. Conditions for the formation of able-bodied territorial communities are provided. The own and delegated powers of the united territorial communities in Ukraine are studied. The factors and subjects of ensuring the financial capacity of territorial communities are singled out and generalized. As a result, the well-established interaction of the subjects of financial relations under the influence of both external and internal factors will help meet the legitimate needs and interests of local communities. The basic legislative bases of the mechanism of voluntary association of territorial communities are generalized. It is determined that the current state of local budgets does not seem to be the best, which hinders the complex tasks assigned to local authorities: scarcity of their own sources of income, almost complete dependence on the state budget, lack of transparency of budgetary relations in providing financial assistance from the center, additional assistance revenues and economic expenditure of budget funds. According to the analysis conducted by the authors, a set of problems of organizational support of local budgets is proposed.

Today, there are problems of increasing economic, social, and financial stability and environmental protection (security) in Ukraine, and they are extremely relevant and important. They necessitate the solution of complex tasks aimed at ensuring the sustainable development of communities by means of effective state policy. The article summarizes and develops an approach to the realization of the national interests of Ukraine in the context of the continuous development of communities. It has received international recognition and is thus a system of views on the movement of economies and communities as their consistent interaction with each other and with nature. Today, it is recognized as a valuable model of the future world civilization, which marks the latest state of social development and is recognized as post-industrial. The theory and practice of sustainable development is a reflection of the objective need for economic reorientation and all social development with urgent consideration of the preservation of natural and human opportunities for current and future generations. For Ukraine, especially in view of its integration policy, the introduction of the concept of sustainable development acquires not only scientific but also political relevance and is one of the significant aspects of improving the efficiency of municipal self-government and achieving the best results. Thus, among the criteria of sustainable development of regions, it is expedient to include the criteria of municipal self-government activities, which would contribute to the dynamic and sustainable development of municipal entities, but the basic and optimal level of implementation of ideas and national interests of sustainable development is the municipal level. Therefore, local authorities should ensure the sustainable development of communities, taking into account the principles of local self-government and creating conditions for the transfer of a minimum economic, ecological and social debt to future generations.

It was determined that the development of territories depends on the choice of strategy, tactics and implementation tools regional policy of the state. And therefore, at the current stage of global transformations, they are expedient and permanently improve, as current practice shows approaches to managing the development of domestic territories. Trends and prospects of development are studied in territorial units of Ukraine in terms of implementation of the chosen strategy and current state regulations and regional policy. The study of the problem was carried out thanks to the application of methods of comparison, abstraction, analysis and generalization, as well as tabular and graphical modelling. It was determined that the prospects for the development of territories primarily depend on the strategy and tactics implementation of the state regional policy, which should take into account the dynamism of socio-economic development, the rate of digitization of the economy and the level of innovation and technology regions of highly developed countries of the world, with which domestic regions are becoming more and more difficult to compete. A set of measures was proposed to optimize the processes of managing the development of territories, in particular, the creation of mechanisms for combating post-pandemic consequences, stimulating purchasing consumer demand at the local level, improvement of tax policy, creation of favourable conditions for improving the qualification level of employees, rationalization of the financial redistribution mechanism resources between different territories, as well as between regional and state budgets, dissemination of effective anti-corruption practices at the local level. Prospects for the creation of territorial ones have been determined by communities taking into account positive and negative factors to reveal strong and weaknesses in order to identify opportunities and threats to their development at the regional level levels using a SWOT analysis. Ways to improve regional policy are proposed.

Nowadays, sustainable development is becoming a model for significant improvements in the modern world. Taking into consideration possible future challenges, transport must have sustainable features. Today, such a type of transportation as intermodal transport (transport that uses more than one mode of transportation) is gaining relevance. It is one of the most promising types of transport from an economic and environmental point of view. In this paper, the importance of sustainable development of intermodal freight transport is analyzed; the state of foreign trade and the trade balance in Ukraine and Poland are examined; and the sustainable development trends and prospects of trade relations between two countries are determined, taking into account the existing product structure. It is noted that the post-war recovery of Ukraine will require the activation of logistical flows with EU countries. The analysis of the state of freight transport by various modes of transport allowed for theoretically justifying the insufficient attention given to the development of intermodal freight transport between Ukraine and Poland for logistics optimization in international trade. From a methodological perspective, it is proposed to describe the subject area in terms of graph theory. The practical contribution involved the testing of the proposed model of intermodal freight transport to optimize logistics flows in international trade between Ukraine and Poland, considering the minimization of transport service costs and time. This required refining the mathematical apparatus based on the method of successive moves and linking their development to specific supply chains.

Research background: Digital ecosystems in Europe are heterogenous organizations involving different economies, industries, and contexts. Among them, Digital Innovation Hubs (DIHs) are considered a policy-driven organization fostered by the European Commission to push companies’ digital transition through a wide portfolio of supporting services. Purpose of the article: There are DIHs existing in all European economies, but literature needs more precise indications about their status and nature. The purpose is to study a distribution of DIHs and differences in portfolios of DIHs’ services across European economies. Therefore, the paper wants to deliver more precise data on effects on national and European policies. This is required to define their final role and scope in the complex dynamics of the digital transition, depending on regional context and heterogeneity of industries. Methods: Data on 38 economies was collected from the S3 platform (on both existing and in preparation DIHs) and further verified by native speaking researchers using manual web scrapping of websites of DIHs identified from S3. To find potential similarities of digital ecosystems in different economies as emanated by the existence of DIHs, clusterization (Ward’s method and Euclidean distances) was applied according to the services offered. Economies were clustered according to the number of DIHs and the spread of DIHs intensity in different cities. The results were further analyzed according to the scope of the provided services. Findings & value added: The applied clustering classified European economies in four different sets, according to the types of services offered by the DIHs. These sets are expression of the different digitalization statuses and strategies of the selected economies and, as such, the services a company can benefit from in a specific economy. Potential development-related reasons behind the data-driven clustering are then conjectured and reported, to guide companies and policy makers in their digitalization strategies.
