Singang is rich in cultural capital, and its Matsu culture impacts the development of Singang Township. This paper focuses on how Singang’s cultural capital is transformed into social capital and affects local development. It adopts exploratory methods and collects data mainly from in-depth interviews. It concludes that cultural capital creates local identity via local organizations, and that the transformation of cultural capital into social capital arises from the following three aspects: the religious culture, centered on Matsu, promotes trust between locals; the local cultural ethos of placing public interest ahead of personal interest forms the interactive norm in Singang Township; and the organizational culture of its citizens’ association strengthens the network of local participation. Social capital also generates spillover effects through community actions, such as free meals during the Dajia Matsu Pilgrimage Procession, the Singang Cleaning Initiative, and two wonderful roads designed to enhance local awareness and boost development.
