The book focuses on a systemic study of the challenges of the modern economy and related problems and areas of sustainable development of countries, regions, and businesses, with particular attention paid to the new prospects offered by the spread of digital technology. The book’s contribution to the literature is that it reveals the specifics and digital perspectives of supporting the SDGs in the economy at every level of the economy: country, regional, and corporate, considering sectoral specificities—this is reflected in six parts of the book. Part 1 identifies contemporary challenges of the modern economy as barriers to sustainable development. Part 2 reflects the future direction of sustainable development of the countries. Part 3 considers the problems and prospects for sustainable development of regions. Part 4 focuses on the problems and prospects for the sustainable development of enterprises and industries. Part 5 sheds light on the economic and legal foundations and cooperative mechanisms of sustainable development. Part 6 offers recommendations for enhancing the use of digital technologies offered by Industry 4.0 to support the SDGs. Scientists whose research interests include sustainable economic development are the primary target audience for this book. For the primary target audience, the book forms a systemic view of the global challenges of sustainable development and offers a set of scientific and methodological recommendations to provide an effective response to these challenges at every level of the economy. An additional audience for the book is practicing experts, who will find international best practices and applied recommendations to support sustainable economic development and implementation of the SDGs in the practice of state (national regulation and public administration of the region) and corporate (in various industries) management.
