With societies like Japan and Taiwan rapidly aging, finding solutions to the ever-pressing challenges of regional decline has become a priority over the past decades. Yet, strategies aiming at regional revitalization did not yet achieve the desired success. One possible explanation for this is a negligence of the holistic character of the issue. Regional decline involves many factors which share an intertwined relationship. A successful solution strategy must therefore consider the underlying patterns and address multiple key factors in order to achieve systemic change. Sedai Group is a private organization aiming to revitalize the historical district of Dadaocheng, Taipei. To achieve this goal, the group has established different concepts and is, amongst others, now engaged in historical building rental and subleasing, start-up incubation, art, tradition, and culture promotion, and online platforms. The driving force behind the group’s model is the creation of a so-called value-based community by supporting social entrepreneurs and enterprises on the one hand and attracting like-minded people to join the community on the other hand. This way, Sedai Group aims not only to contribute to the revitalization of Dadaocheng, but also to become a movement with enough reach and resources to make an impact in solving other major challenges, too. The main contribution of this study lies in combining the core concepts of Sedai Group in a systems map. This systems map shows how the different concepts together contribute to the creation of the value-based community, creates synergies, and how this can benefit Dadaocheng in overcoming decline and can therefore serve as a blueprint for other projects. This research is based on literature reviews on regional decline and regenerative principles. The former is used to confirm that the Sedai Model indeed target key drivers or regional decline. The latter explores criteria to avoid creating strategies that are unsustainable or even create dependencies.
