The development of sharing economy business models is one of the features of the digital economy. The issue of sustainable development has been of particular importance in the intensively developed theory of the sharing economy. However, methodological approaches for examining the relationship between the sharing economy and sustainable development need further investigation. Economic and mathematical models that allow for a quantitative estimate of the impact of the development of the sharing economy on the sustainable development goals achievement have to be enhanced. This contribution attempts to fill the indicated gap. We have examined the relationship between the sharing economy and the sustainable development goals achievement in three directions, namely by analyzing the prerequisites for the sharing economy emergence, by tracing the sharing economy theory evolution, and by investigating the quantitative impact of the sharing economy development on the sustainable development goals achievement. To determine the sharing economy’s impact on sustainable development, a three-dimensional indicator based on the triple-p concept was developed. The correlation between the sharing economy and the unemployment rate has been used as an indicator of the influence the sharing economy has on the social domain. The correlation between the sharing economy and waste generation has been used as an indicator of the influence the sharing economy has on the environmental domain. The correlation between the sharing economy and GDP has been used as an indicator of the influence the sharing economy has on the economic domain. As a result of the study, the insignificant influence of the development of the sharing economy on the achievement of the quantitative goals of sustainable development was established. The main reason for this is the lack of acceptable macroeconomic indicators. The rise of the digital economy has been made into standard macroeconomic indicators that are insufficient to assess the social, environmental, and economic areas of sustainable development. The existing problems of regulating the digital economy threaten its inherent positive features. The developed model can be used to diagnose the influence of the sharing economy on sustainable development goals achievement, and can also be finalized regarding the available statistical base.

Waste generation and use is one of civilization’s main problems. Realizing the goals of the concept of sustainable development is one solution to this issue. Sustainable waste management is impossible without measurements and without assessing compliance with economic, environmental, and social criteria; therefore, quantitative information and indicators play an important role in solving these issues. Methods used to diagnose the sustainability of waste management should include both an assessment of indicators and a diagnosis of the reasons for changes. The approach proposed in this paper is based on the development of an integrated indicator which includes social, economic, and environmental factors, reflects the state of legislative and executive initiatives in the field of sustainable waste management through specific macroeconomic indicators, which should make it possible to identify the causes of sustainable/non-sustainable waste management.

This article focuses on the sustainable, equilibrium development of Russian enterprises engaged in the extraction and processing of gold. The conditions for the effective activity of companies in the field of gold mining were considered. The main factors causing crisis situations and problems in the strategic management of gold mining enterprises of the Russian Federation were highlighted. The main objective of the study was to develop proposals for improving the model and mechanism of the strategic management of the gold mining company. The study analyzed a wide range of theoretical sources, identified gaps in scientific works in contact with the topic of this work. These gaps were associated primarily with the inadequate reflection in the existing models of industrial enterprise management of the specifics of the activities of gold companies and the lack of key components of the model, affecting sustainable business development. The methodological basis of the study was: Systems theory and systems approach, economic and mathematical models of firm management, investment design, theoretical studies in the field of business valuation. In connection with the growing risks, socio-economic instability, the fall in the growth rate of gold mining, the problems presented in the study are relevant. Maintaining competitiveness and improving performance indicators requires the improvement of the process of the strategic management of mining companies. This article discusses the fundamental components of an improved model of strategic management of gold mining enterprises proposed by the authors, presents a graphical model, suggests directions for describing an improved management mechanism for a gold mining company using mathematical modeling methods designed to link the most problematic components and gold mining business processes: investment, technology intelligence and gold mining, capital investment, timing of the project Comrade, the profitability of production. The dynamic simulation model of strategic management presented in this study and strategy assessment tools based on the concept of the organization’s life cycle take into account the specifics of the activities of gold companies in Russia; were introduced into the practice of the enterprises of Siberia, Sakha-Yakutia, which led to increased economic sustainability and improved financial performance of these companies.

This article discusses the issues of improving strategic management of sustainable development of enterprises of the Russian Federation. The management of many companies continues to demonstrate an inadequate attitude to the development and implementation of a system of measures to ensure the proper level of sustainability of an industrial company. The main problem considered in the study is the insufficiently perfect mechanism for the strategic management of the investment policy of industrial enterprises in the Ural region of Russia. The management of many enterprises does not conduct a comprehensive assessment of sustainability and does not rely on the triad of sustainable development indicators—economic, environmental, and social. This negatively affects the strategic management decisions made. Under an insufficiently perfect mechanism, in this study, we refer to the following: At Russian regional enterprises, there is no close connection between the processes of making strategic decisions and the investment policy of the enterprise. This leads to certain errors in the formation of the enterprise strategy. The connecting element of these processes is highlighted. It is a comprehensive assessment of sustainability. The main objective of this study is to improve the model and mechanism of strategic management of the investment policy of the enterprise in the context of the environmental and economic status of the business. The proposed model is based on the principles considered from the perspective of three directions—economic, social, and environmental. This model provides for a close interconnection of components: management decision-making, investment policy development, and comprehensive assessment of sustainable development strategy. Based on the analysis of scientific works, the practice of managing industrial enterprises and certain gaps have been identified in theoretical sources related to the topic, problem, and objectives of the article. The methodological base of the study is determined, and methodological aspects of the analysis of the ecological state of business projects and the formation of strategic management of investment activity of an industrial enterprise are substantiated. The model for managing sustainable enterprise development is presented. This model provides for close interaction between the mechanisms for developing strategic decisions and managing the investment policy of the enterprise based on the environmental component of the business as a factor in sustainable development. Tools are proposed that ensure interconnection and synergy between the components of strategic management of the investment policy of the company and improve the quality of management decisions.
