The purpose of the study is to systematize the challenges of the public economic security in the context of the development of global digitalization. The paper shows that the priority task of economic security, particularly notable in the rapidly changing conditions of today’s globalized world, is to predict the challenges and threats of general digitalization. We have highlighted the features of the digital economy development, which include the intellectual assets, the increase of the relevance of data, network management, wide Internet penetration as well as global data exchange. In the conditions of the digital economy, we have grouped the issues of economic security on system, structural and sectoral problems, as well as the problems of enterprises and individuals. The main problems of economic security are the issues of «digital inequality», a lack of own element base, changes in the labour market, industrial intelligence, personal data manipulation, etc. We have found tools for solving the issues of digital society. These tools include digital platforms for the development of «shared economy», as well as cloud technologies and methods for processing large databases. The Network Readiness Index is a tool for monitoring the development of network digital society. We have formulated the principles for constructing systems for the development of skills, which allow solving the problems of the public economic security in the conditions of digitalization. These principles include the rational use of resources combining short-term and long-term development goals, lifelong learning, consistency, unified approach to management at different levels as well as involvement stakeholders in the process of digitalization. The results of this paper can be useful to public authorities for the development of the principles of digital economy management, as well as to the representatives of scientific community for the study of the economic security issues in the conditions of digital society development.

The study aims to systematise the existing methodological approaches to assessing the development of smart cities, elaborated by a number of international institutions (organizations). Moreover, it identifies characteristics of the assessment and possibilities of its application in the Russian context. We considered the fundamentals of a smart city’s development as our research object. Methodological approaches to assessing the development of smart cities are our research subject. We analysed scientific research, published in the periodical press, as well as the results of the authors’ study on the digitization processes of socio-economic systems, the principles of the urban environment’s digitization, and the urban development’s fundamentals based on the smart city’s concept. The research method is a logical analysis of modern approaches to assessing the development of smart cities. The paper identifies and analyses the main characteristics and conditions for the effective functioning of smart cities. We consider a model of the development levels of a smart city. Furthermore, we demonstrate the importance of cooperation among stakeholders in the field of the urban environment’s development, as it creates new opportunities and ensures the long-term viability of smart cities’ projects. We note that one of the most important factors in the development of smart cities is the increment in human capital of their inhabitants. Lifelong learning and advanced training are becoming a condition for the development of modern socio-economic systems. The dominant role of highly-skilled creative work becomes the determining factor for the development of a new type of society and its inherent economy. In the paper, we have described and systemized the main approaches to assessing the development of smart cities. We have formulated a number of principles for constructing a methodology for assessing smart cities. The study has theoretical relevance due to the development of approaches to assessing the development of smart cities. The practical significance of the research lies in shaping possible future studies of rational economic management in the context of the digital society.
