Abstract: The article deals with the problem of a collective subject in the conditions of the spread of digital communications. The classification of collective subjects is a definite problem for legal science. There are social, political, and economic collective entities. A collective entity exists under the following conditions. Firstly, there should be a possibility of constant communication between the members of the team. Secondly, the team conducts one or more types of common activities. Thirdly, the team members participate in the development of directions and ways of future activities. Fourth, they can directly or indirectly influence decisions on the choice of one of the proposed options for future activities. The spread of digital communications significantly increases the connectivity of large teams. There is a possibility of existence of geographically distributed collective entities, whose members are located in different countries. The research method is based on the analysis of changes in the ways of communication between individuals who make up a collective subject. Digital networks allow for discussions (including those protected by cryptography), voting, foresight, the use of digital signatures, and automatic logging of all communication. Compared to telephone communication, digital communications allow the simultaneous participation of hundreds of people (collective chat). The speed of e-mail transmission is thousands of times higher than the speed of written messages. The new tools allow for video conferences with demonstrations of graphic and tabular materials. Voting using secure protocols and digital signatures is possible. There are decision support systems, computer models (digital doubles) of objects that need to be managed to make decisions. All this leads to a significant change in the quality and effectiveness of collective subjects. New types of collective actors (virtual communities) are emerging, which ultimately influence events in the real world. Legal science needs to start studying the processes of digitalization and comprehend their theoretical significance for jurisprudence.

Abstract: The subject of the study is the interaction of the ideal and material components of political, cultural and socio-economic processes influencing them in large socio-economic systems such as religions, sciences, ethnic groups, regions and states. The concept of social ideo-material polysystems (SMPS) is proposed. IMPS are holistic systems that include social, cultural and economic components that make up a complex society. A feature of such systems is that some of the elements of these systems are material, and some are ideal. A polysystem is a supersystem consisting of fuzzy irregularly interacting ideo-material systems (IMS). It is substantiated that IMPS, consisting of people, artifacts and biological organisms, form integrity due to the system of ideas that unites them. It is the systems of ideas that give meaning to social IMPS, uniting communities, determining their behavior and direction of development. Approaches to the quantitative study of ideal subsystems of IMSI are proposed.
Methods: use of systemic, holistic, evolutionary and informational approaches.
The highest type of IMSI are civilizations, the most complex known systems in the Universe. A feature of such systems is that some of the elements of these systems are material, and some are ideal. IMS, consisting of people, artifacts and, in some cases, animals and plants, form integrity due to the system of ideas that unites them. These ideal systems manage social IMS, unite communities, determine their behavior and direction of development. IMS are very diverse: they can be scientific communities in which science brings together scientists, scientific instruments, theory, texts, social institutions, buildings; these can be religions in which the scripture unites priests, parishioners, temples, sacred texts and attributes. The complex of ideas on which these systems are based is of a holistic character.
Conclusions: The proposed concept of ideo-material polysystems can be used to deepen the study of political systems.

Abstract: This article is dedicated to examination of the questions of interinfluence of digital and traditional economy in the regions of the Russian Federation. On the one hand, digital economy stimulates the development of traditional economy; while on the other hand, digitalization requires acquisition of equipment, digital communication services, software, and recruitment of qualified personnel. The interaction of digital and traditional economies differs in the regions with commodity sector, industrial regions, mixed economy regions, metropolitan areas, and territories with low population density. The growing importance of digital economy in the overall development of the regions and the country requires comprehensive examination of digitalization processes with regards to both, economy and society. The scientific novelty consists in the use of big data for tracing correlations between the available indicators of development of digital economy and various aspects of traditional economy established in the Russian region. Based on the database of the Unified Interdepartmental Information Statistical System, the author constructed scatter diagrams, calculated correlation coefficients and trend lines to determine the interdependence of these indicators. The article examined the link between the number of personal computers in the region, level of public access to the Internet, GRP, cost of labor, and users of satellite communication systems. The author determines the instances of positive and negative interinfluence, and discusses the probable causes their different vector.
