The article examines the impact of new economic conditions against the backdrop of the COVID-19 pandemic on the trade enterprises competitiveness using the example of the market of building and finishing materials. The aim of the study is to identify the qualities that a manager, who is able to bring an enterprise out of a crisis state with the least consequences for it, should possess, to develop a model for managing the competitiveness of trade enterprises by forming a set of corrective measures aimed at ensuring the competitiveness of services accompanying the trade in construction and finishing materials. Theoretical studies were carried out using the methods of system analysis and generalization of the existing scientific developments in the field of managing the trade enterprises’ competitiveness [1]. The methods of statistical analysis were used to determine the crisis impact assessment on the competitiveness of trade enterprises and to identify the competitive advantages of the industrial analyzed segment. As a result of the study, the following results were obtained.: - analysis of trends in the retail industry revealed the main problems of trade enterprises in the context of the crisis caused by the spread of a new coronavirus infection; - the use of the fundamental principles of the formation and maintenance of the organization’s competitive advantages made it possible to determine the competitive advantages of trading enterprises in the market of building and finishing materials, using digital technologies in business, allowing to maintain a stable position in industrial market; - relying on a system of long-term competitive advantages, the main activity areas of trade enterprises were identified, which, thanks to corrective solutions, are able to ensure sustainable development in the context of overcoming the crisis caused by the COVID-19 pandemic.

The objective reasons for assessing the role of institutional investors as valuable participants of the Russian financial market and forecast trends within the framework of various projects is explained by the necessity of optimizing their participation in serving the needs of national and international economy as well as using the tools of environmental policy promotion. The subject of the research is the activity of institutional investors in contemporary environment and possible ways of making them as financial intermediaries more effective in providing the needs of the modern economy, especially in the fuel and energy complex as a key sector of the Russian Economy. The article provides a comparative analysis of the current set of factors and threats that affect the prospects of participation of institutional investors in financial markets. The complex analysis methodology, used in assessing the problems, involves considering the standpoint of the influence of a set of factors, subdivided into internal and external. Internal factors include the national market conditions and environmental issues. External factors reflect the long-term impact of a potentially adverse or favorable impact on the course of projects implementation based on institutional investors’ facility in spite of market turbulence, political sanctions or pandemic conditions.

The article reveals the concept of a logistics unit, logistics and digital hubs. The aim of the study is to assess the competitive prospects for digitalization of the Russian logistics block of the Northern Sea and New Silk ways as a set of international logistics and digital hubs, as well as exhibition complexes and educational sites. The research is focused on combining the logistics sections of the Northern Sea Route and the New Silk way into a single logistics system with its further registration in digital space. The main goal of this system is to unite all available resources of the Russian Federation in its block of the international logistics system to attract the largest number of partners and customers. It is considering the possibility of combining the Northern Sea and New Silk way sections into a single system on the territory of the Russian Federation. The authors investigated the ways of digitalization of the logistics block of the NSR-NSW with the subsequent creation of a virtual space for the control and redistribution of trade throughout the Russian Federation. During the research, studies were conducted in the field of public administration, which use modern digital communications and digital security systems. Possibilities of implementing a system of digital hubs based on the results. As a result of the study, potential positive results from the implementation of the project of digital inter-hub networks in both the economic and social sectors were highlighted.

Energy Internet is centered on electricity, based on a strong smart grid, and deeply integrates advanced information and communication technology, control technology and advanced energy technology to support the clean and low-carbon transformation of energy and electric power, comprehensive utilization efficiency optimization of energy, and the access of flexible and convenient multiple entities, which is a smart energy system with the characteristics of green safety, ubiquitous interconnection, efficient interaction, and intelligent openness. This article focuses on the impact of the development of the Energy Internet on power grid companies and the main business of power grid companies in the future development environment of the Energy Internet, providing references for the transformation and development of power grid companies.

Morocco, like the rest of the world, is experiencing a climate change that threatens a number of wetlands. Marine ecosystems contribute to the regulation of the Earth’s climate, but their degradation releases large quantities of greenhouse gases (GHGs) such as carbon dioxide (CO2) into the atmosphere. This paper aimed to map and model changes in carbon storage and sequestration for coastal habitats using the INVEST model, using the Sidi Moussa-Oualidia lagoon complex as a case study. To achieve this objective, several data were used, namely, land use and land cover maps between 2003 and 2020, as well as data on the amount of carbon stored in the three basins; biomass, sediment carbon (soil) and dead carbon (litter), and the annual rate of carbon accumulation in biomass and sediment. The results obtained in this work allowed us to compare the two former and current carbon stock and net sequestration scenarios and to evaluate the social cost of carbon in the study area. This study can facilitate the development of a coastal rehabilitation strategy to take advantage of the benefits of these wetlands and, at the same time, to conserve the ecosystem services provided by these environments, including the CBCS.

The article is devoted to the application and formation of new scientific approaches and practical recommendations for the use of information modeling technology in the activities of enterprises of the construction complex at the stages of the life cycle of the construction of real estate objects. Research methods are theoretical analysis and empirical study. The object of analysis is the enterprises of the construction complex in the conditions of the formation of the factor space at all stages of the life cycle. Quantification of factors influences the outcome. The article proposes new scientific, practical approaches to the functioning and development of enterprises of the construction complex in conditions of risk, as well as factors of uncertainty in construction production based on the use of information modeling technology, the use of effective models for managing the construction of facilities. A flexible management model is proposed that allows you to respond to all changes in the external environment, timely manage costs, including the timing of work, which allows you to quickly adjust the progress of production processes in space and time when any types of risks occur.

Based on the research of Marine plastic garbage recovery method, the discussion of the recovery device and the understanding of the types of ships, this paper designs a multi-stage recovery device for Marine plastic garbage. This device according to the types of the existing Marine plastic garbage and recycling requirements, effective implementation for big (more than 50 cm diameter or width), medium (diameter and width are between 5 mm ~ 50 cm) and micro (diameter or width under 5 mm) type size grade plastic debris automatic classification recycling, determined the primary barb type crawler collection device, second level network intercept type garbage collection device and the third level based on the sponge and activated carbon micro plastic collection device. Recycling and storage of Marine plastic waste to effectively address Marine plastic pollution is consistent with the MARPOL convention on the protection of the Marine environment.
