The Implementation Path of “Endogenous Development” in the Transformation of Fishing Ports and Spatial Design: A Case Study of Xiangzhi Fishing Village in Quanzhou City

Fishing harbors often face a range of challenges during their transformation process, including cultural disruption, spatial alienation, the erosion of vernacular values, harm to the interests of local villagers, and a lack of sustainable development momentum. In response, this study explores a sustainable and endogenous approach to transforming and renewing fishing villages. Grounded in the theoretical framework of endogenous development, the paper constructs a transformation model for fishing harbors driven by internal dynamics. It emphasizes the spatial dimension of fishing ports as a key node within the broader fishing village system, serving the integrated functions of production, living, and ecology, and presents an empirical case study of Xiangzhi Fishing Village in Quanzhou, a representative example. The study proposes a design model based on the synergistic interaction of local elements, spatial carriers, and principal actors. The findings suggest that this model not only offers a practical pathway for the sustainable transformation of traditional fishing villages but also provides theoretical guidance and a reference framework for similar regional development efforts.
