Nowadays, information technology and the Internet are becoming a driver for a shared consumption economy (sharing economy). The paper aims to analyse the current level of use and prospects for the development of models of the sharing economy in Russia. We identify the effects of sharing consumption for the circular economy and study factors that stimulate the use of peer-to-peer models. One of the study’s tasks was to investigate the involvement of the young generation in the sharing economy, as the most promising part of the population. The study is based on the analysis of open Internet sources on the operation of sharing platforms in Russia and a survey among students at two Russian universities (RUDN University in Moscow and Kuban State University in Krasnodar) to identify the awareness of young people regarding sharing platforms. Analysis of the current state of sharing in Russia showed that the use of most types of sharing is at an initial stage. At the same time, the prospects for economic growth and population development are quite high. The article identifies several effects of digital platforms for sustainable development, the main of which are informed consumption and production. For the further growth of users of the sharing economy, the authors highlight the level of penetration of the Internet and the need for high-quality services on digital platforms. Educational organisations can also become a platform for the development of models of the sharing economy by involving students in sharing processes, as demonstrated by the survey.
This paper contributes to the literature on sustainable consumption by in-depth analysis of the factors affecting the probability of 57 different practices of proenvironmental behavior (PEBs) in Russia. The set of studied PEBs includes not only popular energy-saving and waste-management practices but also more circular patterns of plastic consumption, shopping, and city mobility. To study real and potential barriers to greening consumer behavior models, we conducted a survey of 623 respondents using a questionnaire developed based on a comparative analysis of similar studies conducted in other countries. The processing of the survey results was carried out using nonparametric statistics due to the absence of a normal distribution of the sample for most of the studied characteristics. The results of the study revealed that the main barriers to sustainable consumption in Russia are the lack of appropriate infrastructure as well as a lack of knowledge. Infrastructural barriers in some situations makes sustainable consumer behavior impossible or inconvenient (in this case, preference is given to other types of consumption), or in some cases necessitates spending additional time and money (then sustainable consumer behavior is not completely denied but practiced less often).
Due to the rapid development of recycling technologies in recent years, more data have appeared in the literature on the environmental impact of the final stages of the life cycle of wind and solar energy. The use of these data in the eco-design of modern power generation systems can help eliminate the mistakes and shortcomings when planning wind and solar power plants and make them more eco-efficient. The aim of this study is to extend current knowledge of the environmental impacts of most common renewables throughout the entire life cycle. It examines recent literature data on life cycle assessments of various technologies for recycling of wind turbines and photovoltaic (PV) panels and develops the recommendations for the eco-design of energy systems based on solar and wind power. The study draws several general conclusions. (i) The contribution of further improvements in PV’s recycling technologies to environmental impacts throughout the entire life cycle is insignificant. Therefore, it is more beneficial to focus further efforts on economic parameters, in particular, on achieving the economic feasibility of recycling small volumes of PV-waste. (ii) For wind power, the issue of transporting bulky components of wind turbines to and from the installation location is critical for improving the eco-design of the entire life cycle.
In order to effectively regulate the circular economy (CE) at the national and international levels, it is essential to have a unified and informative system of indicators for monitoring the progress in the CE. The lack of standard indicators for measuring the progress of cyclicality leads to contradictions and misunderstandings, which is a problem for the implementation of CE strategies. This paper aims to adapt dynamic clustering approaches to solving strategic management problems of circular production and consumption processes. To achieve this goal, the authors performed the following tasks: (1) tested clustering algorithms by ranking EU countries by the level of development of the circular economy; (2) identified the approach that allows the best classification of EU countries, considering changes in the indicators of the level of CE development in 2000–2019 (dynamic classification); (3) developed a software module using python libraries to classify and visualize the results. The results illustrate that the k-means algorithm has a good discriminatory ability in division of all countries of the training sample (EU countries) into several clusters with different dynamics in the development of the CE. The best quality of classification is obtained by the indicator “Generation of municipal waste per capita”; satisfactory quality of the classification is obtained by the indicator “Generation of waste excluding major mineral wastes per GDP unit”. The study results demonstrate the fundamental applicability of the object-oriented and classical statistical approach to solving strategic management problems of the CE and their potential effectiveness in terms of the clarity and information content of reflecting cyclical processes.
The article discusses the current situation of the formation and development of the digital economy in the BRICS countries. The comparative analysis of the BRICS countries based on key requirements such as availability and reliability of the data, the possibility of crosscountry comparisons. As comparative techniques analyzed international integrated (composite) codes for up to one scale evaluation plurality of objective and subjective parameters. It has been shown that digitalization has a positive effect on per capita GDP growth only after reaching the distribution and use of ICT at a certain critical point. To obtain a positive response in the economy from digitalization, a certain period is required for organizations and the public to master new technologies and adapt to them. It was found that the ICT index is not yet sufficiently informative to assess the level of welfare since it gives a significant positive impact on the economy with a time lag. An analysis of the components of the telecommunications infrastructure index showed that Russia, Brazil are close to their saturation point, and India, South Africa, and China have very good sources of growth. The e-government development index and the telecommunications infrastructure index showed a high degree of correlation. Used summation method showed that now in Russia a degree of readiness for the formation of the digital economy has reached almost the maximum value, while those of the BRICS countries like China, India and South Africa are still in their infancy, but there are significant advantages to accelerate the digitalization process. For the digital economy to become a reality for all the BRICS countries, serious government measures and large investments are required, both in the development of infrastructure for access to the Internet and in investment in human capital.
