In Part I, the case of Grameen Euglena in Bangladesh and that of Sari-Sari stores leveraging micro-financing in the Philippines, along with other interesting cases, are analyzed as effective social business models. Analysis also shows that the IT service industryin emerging countries helps to enlarge formal sectors so as to absorb younger generations into informal sectors. The e-health service business in Bangladesh and the business process outsourcing (BPO) IT service industry in the Philippines are examined in each part of the book. Part II, particularly, shows that IT and the digital technology-based service industry can lead to a new industrial development path in these countries instead of the conventional one based on manufacturing. In other words, digital technology-based service industries, as formal sectors, can absorb working people from informal sectors. As a result, poverty issues which form a key issue in SDGS will be alleviated. This book is highly recommended not only to academicians but also to businesspeople who seek an in-depth and up-to-date overview of new sustainable and inclusive businesses in the age of SDGs.
