КЛЮЧИ К УСТОЙЧИВОМУ РАЗВИТИЮ АРКТИЧЕСКОЙ ЗОНЫ РОССИЙСКОЙ ФЕДЕРАЦИИ: МОДЕЛЬ ЦИРКУЛЯРНОЙ ЭКОНОМИКИ И ЛОГИСТИЧЕСКАЯ ИНФРАСТРУКТУРА

The article examines the infrastructure approach to the implementation of the concept of sustainable development in the Arctic zone of the Russian Federation (AZRF). This is done from the point of view of compliance of this development with the so-called megatrends of the world economy, highlighting theoretical, conceptual, and technological aspects. he characteristic of modern geoeconomic and geopolitical factors of development of the AZRF is given. A brief comparative analysis of applicability of economic models that are relevant the concept of sustainable development in the case of the Russian Arctic: bioeconomy, green economy, and circular economy. A few conditions for the implementation of the circular economy model in the Russian Arctic is considered. In connection with the representation of the AZRF as a heterogeneous socio-economic, real-virtual, socio-cyber-physical space, a special role of logistics infrastructure is shown as necessary condition for ensuring the sustainable development of this largest Russian region. The emphasis is made on the need to conceptualize the concept of "logistics infrastructure". Based on a holistic approach to logistics, a 5-layer (underwater, water, ground, air, space) conceptual research holistic model is proposed that could be used for designing, constructing, and monitoring the system of logistics flows in the Russian Arctic. The result of an analytical assessment (in dimensions of "digitalization" and "sustainability") of the state of the Art and possible development for the underwater layer of the logistics infrastructure of the Russian Arctic. The conclusions of the article could be useful both for designing the logistics infrastructure of the Russian Arctic, and for designing the courses of disciplines of higher education relevant to the problem under consideration.
