Abstract: Integrating the protection and revitalization of minority religious architectural heritage with modern societal development is a critical challenge in balancing cultural preservation and regional economic growth. Based on the neo-endogenous development framework, which emphasizes resources, participation, and identity, this study constructs an analytical framework tailored to the unique and rich cultural contexts of minority villages. Using Husa Village in Longchuan County, Dehong Prefecture, Yunnan Province, home to the Achang Ethnic Township and rich in religious architectural heritage, as a case study, the paper analyzes the current status, identifies key challenges, and proposes strategies across four dimensions: natural and architectural heritage conservation, traditional craftsmanship and ethnic arts preservation, cultural tourism revitalization, collaborative governance by enterprises and local communities. Follow-up fieldwork further explores the impact of the neo-endogenous development model on sustainable heritage management. The findings offer insights to effectively preserve minority religious heritage while fostering local cultural, economic, and social development, providing a reference for similar efforts in other minority regions.
