The development of digital twins of the urban ecosystem is gaining popularity and is the mainstream of the digital development of the territories of the world. Already today, there are domestic developments for the creation of digital twins, including the urban ecosystem. The aim of the article is to provide a theoretical description of the essence of the digital twin of a city and an overview of existing platforms for creating digital twins of an urban ecosystem to ensure the quality of life of the population. Research objectives: to identify the prerequisites for the creation of digital twins; to determine the essence of the definitional basis of the digital twin in the context of existing theoretical analogs; to characterize the conceptual foundations of creating digital twins of the urban ecosystem in Russia and the world, to identify the advantages of their development to maintain the quality of life of the population; to give an idea of the methodology for the development and functioning of digital twins of the urban ecosystem; to conduct a comparative analysis of the capabilities and functionality of digital platforms and technologies for the development of digital twins of the urban ecosystem; to conduct a comparative analysis of the existing digital twins of the urban ecosystem of the world. As a result of the study, data on existing domestic digital platforms and technologies for the development of digital twins of the urban ecosystem were obtained, their comparative analysis was carried out, advantages were identified, and the possibility of achieving technological leadership and competitiveness in this area in the world market was determined. Descriptive, analytical, and comparative methods were used as research methods. The results of the study showed that the use of digital twins of the urban ecosystem will allow municipal authorities to obtain effective levers of management, and the population -to ensure a high quality of their own life.

The article is devoted to the analysis of publication activity of the flagship university (scientometric indicators of teachers and researchers) as one of the key indicators for assessing the contribution of the flagship university to the social and economic development of the region. While solving the research tasks, the authors defined the list of scientometric indicators for assessing scientific results, analyzed the scientometric indicators of development of Yaroslav-the-Wise Novgorod State University (Veliky Novgorod) for the past three years, determined the importance of a further increase in publication activity of the university for a positive influence on the regional development. The authors consider the strategy for transformation and integration of the flagship university into the University-Region ecosystem of the regional innovative development fixed at federal and regional levels, in order to introduce advanced and knowledge-intensive technologies into the digital economy of the territory. The authors described the first results obtained within the indicated collaboration and the performance of the university as an autonomous strategic agent of regional transformations. The authors outlined the main directions of innovative development of Yaroslav-the-Wise Novgorod State University and the Novgorod Region as an advanced scientific and technological center (in the field of intelligent electronics among others), the center for developing social, anthropologic, cultural, urban and other studies which determine current and future directions of the university's publication activity. The authors note an increase in scale and effectiveness of research due to the interaction between the region and the flagship university, which manifests itself both in the growth of publication activity and in an increased volume of attracted grant funds which, in turn, are the source of financing scientific publications. The number of publications co-authored with residents of other states and industrial partners increased. To obtain results, the authors used a comparative method (quantitative and qualitative analysis), modern tools for bibliometric analysis, forecasting, an economic and statistic method.

The study is aimed at analyzing the sociality of regional socio-economic development strategies. In any of them, economic and social components can be distinguished. The social part is usually understood as a target one, aimed at meeting the various needs of the population, and the economic part as providing, creating conditions for the implementation of the former. The social aspect of strategies is expressed through the goals and development plans of either branches of the social sphere (health, culture, education, social protection, leisure, sports, etc.), or social policy, which has similar directions, or constituent elements of the quality of life. With different target interpretations, we are talking about similar social tasksincreasing incomes of the population, ensuring an increase in life expectancy, strengthening health, creating a comfortable living environment, improving sports, leisure and cultural infrastructure, developing a system of upbringing and education, supporting vulnerable categories of the population, ensuring security, etc. Analysis of the Strategy for the socio-economic development of the Kemerovo region -Kuzbass for the period up to 2035 showed the priority of social attitudes in formulating the region's mission, interests and principles to be realized. But with the concretization of development directions through priorities, the economic bias of the strategic document began to manifest itself to a greater extent. At the same time, it was found that the actual social problems of the territorial community in the long term are not fully taken into account. This was confirmed by the results of a study of the public opinion of Kuzbass residents and an assessment of the expert community, which included poor medical care, unemployment and difficulties in finding a job, a low standard of living of the population, poor ecology, etc., among the most important problems for the region.
