At the current stage, developed economies are able to implement measures to improve energy efficiency. At the same time, the developing economies mostly focus on rapid development, which implies a rapid increase in energy demand. The introduction of innovative technologies should meet the energy needs of economies while simultaneously improving energy efficiency. In particular, this applies to increasing renewable energy consumption. The development of this sector can be accelerated through the introduction of Industry 4.0. The aim of the study is to determine the impact of Industry 4.0 on modelling energy scenarios of developing economies. The research involved methods of analysis and synthesis, economic and statistical analysis, graphical methods, and the comparison. The study revealed a high impact of Industry 4.0 on the Ukrainian economy, in particular energy sector. Among other things, an improved energy efficiency is the result of such impact. It was determined that renewable energy consumption in Ukraine increased significantly by 11.5 times during the studied period. The differences in the energy development of Ukraine and China are outlined: China has chosen energy independence. It was concluded that the development and implementation of the latest technologies play a significant role in energy scenarios. The timing of achieving the goals are the main difference in energy scenarios between developed countries and developing countries. The prospect of further research should be the determining means of measuring the impact of uncertainty on the energy modelling.

The purpose of the study is to substantiate the effectiveness of innovative and investment activities of enterprises within the functioning of eco-industrial parks in the circular economy context. The methodological basis of the research is system and synergistic approaches, the application of which makes it possible to study innovation and investment activities of enterprises that are part of the eco-industrial park as certain subsystems, which in the end, as components of the park, provide a synergistic effect. It is substantiated that the unification of production enterprises within eco-industrial parks consists in a more integrated interaction of enterprises, including through joint investment. The proposed methodical approach to calculating the efficiency of innovation and investment activity of enterprises included in ecoindustrial parks and its approval proves the possibility of obtaining a positive effect from investment activities and investment in innovative projects by enterprises united in ecoindustrial parks in the context of the circular economy. The analysis of the share of production enterprises that implement innovations, as well as the share of the volume of innovative products sold to the total volume of manufacturing enterprises prove the need to intensify the innovative activity and the introduction and development of eco-industrial parks. The advantages of innovation and investment activities within eco-industrial parks in the circular economy context are highlighted.

The article presents the authors’ views on the essence of analysis of personnel innovative potential of an enterprise. Using a system approach, the analysis of personnel innovative potential is considered as one of the functions of the management system. The authors’ method of analysis of enterprise personnel’s innovative potential is suggested, within which the goals, tasks, an object and subjects of analysis, as well as stages of analysis of personnel innovative potential are determined. The sequence and essence of these stages reflect the authors’ view of the analytical procedures concerning the object of analysis and allow selecting relevant analytical tools considering the time domain, the structure of personnel innovative potential and other components. The choice of methods of analysis of personnel innovative potential is substantiated, their characteristic is given within the limits of this research.

The European Union is pursuing an ambitious energy policy to reduce the emission of pollutants into the environment and achieve complete decarbonization by 2050. According to the approved Green Deal, each European state had to introduce its own energy strategy based on its own economic, social, climatic, and climatic conditions. In the process of European integration, Ukraine has developed its own strategies that meet the principles of European government policy. The analysis of the experience of implementation of energy strategies of different member states of the European Union will have a positive impact on the process of implementation of the new energy policy in Ukraine. According to this, a comparative analysis of strategies and the state of the fuel and energy complex of France, Austria, Poland, which have common features with the energy system of Ukraine. As a result of the study, it was found that the process of decarbonization should be gradual. Abrupt changes can lead to negative consequences in economic and social aspects. The information obtained can be useful for energy reforms in Ukraine.

The article is devoted to the issue of relevance and development of social entrepreneurship in Ukraine. Social entrepreneurship is a relevant way of development of any society, as it combines a social mission with a business approach. The relevance of social entrepreneurship is determined by the fact that it can provide solutions to social problems that cannot be solved by the state or commercial organizations. Social enterprises can work in such sectors as health care, education, ecology, social assistance, and others. They ensure the development of socio-economic systems and reduce the impact of inequality on society. The article examines the factors that influence the growing popularity of the implementation of social entrepreneurship, among which the need for innovation, increasing public interest in social issues, and others can be highlighted. Based on this, the advantages and disadvantages of social enterprises were determined. The experience of conducting this form of business in the most successful European countries, such as Great Britain, France, Germany, and the Netherlands, is also analyzed. There are many successful examples of social enterprises implemented in Ukraine. The authors also proposed several ways of implementing social entrepreneurship projects with the aim of post-war recovery of Ukraine. The purpose of the article is to clarify the basic principles of social entrepreneurship, the reasons for its growing popularity in Europe and Ukraine in particular. Also, to analyze the experience of the most successful European countries in the implementation and support of social enterprises, as well as to investigate aspects of the development of this business in Ukraine. To propose possible options for the post-war recovery of Ukraine through the implementation of social entrepreneurship projects. Even though the number of scientists who researched the issue of social entrepreneurship is large, in today's realities there are very few works that consider the issue of social entrepreneurship as part of the post-war reconstruction of Ukraine. The authors show in the article that social enterprises create innovative solutions for social problems, create new jobs and reduce unemployment. They also provide affordable services for the population, solve problems in the fields of education, health care and ecology
