Scientific research plays an important role in the achievement of a sustainable society. However, grasping the trends in sustainability research is difficult because studies are not devised and conducted in a top-down manner with Sustainable Development Goals (SDGs). To understand the bottom-up research activities, we analyzed over 300,000 publications concerned with sustainability by using citation network analysis and natural language processing. The results suggest that sustainability science’s diverse and dynamic changes have been occurring over the last few years; several new topics, such as nanocellulose and global health, have begun to attract widespread scientific attention. We further examined the relationship between sustainability research subjects and SDGs and found significant correspondence between the two. Moreover, we extracted SDG topics that were discussed following a convergent approach in academic studies, such as “inclusive society” and “early childhood development”, by observing the convergence of terms in the citation network. These results are valuable for government officials, private companies, and academic researchers, empowering them to understand current academic progress along with research attention devoted to SDGs.

In the age of systems, the innovation occurs through building a socio-technological system. Therefore, the need for scientific basis of building desirable systems and managing them effectively is increasing and urgent. At the same time, the increasing complexity and uncertainty of the surrounding environment create serious hurdles in designing, constructing and managing systems. This paper proposes a new category of research for building a big socio-technological system, in order to resolve the difficulty of building systems and embedding it in the society. This new type of research includes the whole process of planning based on the completely rational ground and genuine viewpoint of social expectations. It also includes the estimation process of the real performance of systems after it was built in the society to enable the system to evolve in pace with the societal changes. The new research concept proposed here will hopefully form an essential part of innovation.
