The digital economy has become a strategic high point of competition among countries and a new driving force of global economic growth in the new era, and all countries in the world are facing an important strategic opportunity period. This paper shows the value and potential of the digital economy by theoretically  summarizing and analyzing its basic connotation, including its basic definition, development history, dissemination mechanism, and development law. The study released by the United Nations Conference on Trade and Development concluded that the epidemic crisis has intensified the digitalization process of the whole society, and the use of digital solutions, tools, and services has brought positive economic growth, which has also inspired many countries to find new breakthrough points for economic growth and accelerated the transformation of the global economy to digitalization. The digital economy in the post-crisis era will continue to accelerate this trend, and the underlying trends of the global digital economy will further strengthen, which will bring profound impacts and changes to digitally vulnerable countries. This presents an important research direction for studying the digital economy to enhance ESG development today. 10.48554/SDEE.2022.4.1 338 digital economy development trend information economy network economy smart economy https://sustainable.spbstu.ru/article/2022.6.1/ 4_1_1.pdf

Natalia Zhejiang International Studies University, Hangzhou, PRC Wang Diankai Organisational and economic model of innovation and resource potential management of a water supply enterprise in the context of sustainable development This paper is devoted to the problems of managing the innovation and resource potential of water supply enterprises for the purpose of their sustainable development. The study develops an organisational and economic model of innovation and resource potential management of water supply enterprises, tests the model within the activities of a particular enterprise, and, consequently, forms recommendations to improve the management of the innovation and resource potential of the water supply enterprise. The creation of the model is based on the results of earlier studies in which we proved the necessity of using the term “innovation and resource potential of an enterprise” in scientific and practical vocabulary. We previously substantiated the significance of considering innovation and resource potential, studying its essence and structure in relation to water supply enterprises as economic entities that implement the most important goal of sustainable development associated with providing the population with high-quality drinking water. Our previous methodology assessed the innovation and resource potential of a water supply enterprise. The present study applies various methods of analysis, synthesis, structuring, and generalisation, as well as regression analysis. In the proposed model, the external and internal environments and input and output parameters specific to water supply enterprises are reflected in their interrelations. The model is tested on the example of the State Unitary Enterprise “Vodokanal of St. Petersburg”. In particular, the influence of the introduction of an intelligent automated system of management in Saint Petersburg’s water supply system on the value of the innovation and resource potential (in terms of its sub-potentials) and on the resultant indices of the enterprise performance is evaluated. We propose guidelines for managing each structural element of innovation and resource potential. 10.48554/SDEE.2022.4.3 338.242 sustainable development innovation and resource potential water supply enterprise drinking water production management model https://sustainable.spbstu.ru/article/2022.6.3/ 4_3.pdf

Diagnostics of changes in the demographic situation, as well as the intensification of migration processes, showed an increase in both quantitative and qualitative indicators of migration and in the forms and directions of movement of the migration vector. The findings suggest that migration processes have a significant impact on the socio-economic situation in the republic, the balance of the labour market, and changes in the economic and social situation of the population. These outcomes are often accompanied by a change in the vector of educational and professional training, and the expansion of the needs of people participating in migration. 10.48554/SDEE.2022.4.4 314.7 migration sustainable development demographic processes population natural increase population mortality life expectancy poverty level number of immigrants number of emigrants migration policy https://sustainable.spbstu.ru/article/2022.6.4/ 4_4(1).pdf

Yeltsin, Bishkek, Kyrgyz Republic Nuralieva Cholpon Development of methodological provisions for rational material cutting in lean manufacturing at mechanical engineering enterprises In the market economy, mechanical engineering enterprises require continuous improvement of business processes to ensure their competitiveness and sustainable development. Improving business processes based on lean manufacturing and management accounting allows for gaining competitive advantages in the value-creating flow for the consumer and increasing the economic efficiency of the enterprise’s operations. This study takes into account the need to improve the management of material resources being cut at mechanical engineering enterprises with single and serial production types. The main direction for improving the cutting process of industrial materials is to increase their utilisation rate through the use of rational cutting methods. However, this study identifies unresolved problems in theory and practice related to managing business and non-business material resources obtained after cutting, which affect the elimination of material and time losses arising in the process of cutting. Among the main study results are advanced terminological apparatus in the field of cutting industrial materials, advanced techniques for sorting material resources obtained after cutting and methodological provisions for their valuation, methodological approach to assessing economic efficiency of the sorting decision, and software package prototype with elements of the decision-making support system for sorting materials obtained after cutting. The implications of these results are discussed, and directions for future research are suggested. 10.48554/SDEE.2022.4.5 658.5 lean manufacturing managerial accounting material resource management mechanical engineering enterprises development of rational material cutting business material resources sorting technique https://sustainable.spbstu.ru/article/2022.6.5/ 4_5.pdf
