Abstract: Since modern times, overseas Chinese from southern Fujian have traveled to Southeast Asia to make a living, returning large amounts of silver to their hometowns. This promoted the gradual modernization of traditional architecture and accelerated the renewal and development of settlement spaces. Liuchuan Village in Jiaomei Town, Zhangzhou City, Fujian Province serves as a typical case for studying settlements in southern Fujian's overseas Chinese towns influenced by the modern overseas Chinese remittance industry, which fueled settlement construction. From the perspective of the business of overseas Chinese postal agencies, this paper establishes a connection between the development stages of this business and the spatial changes of settlements. By interpreting official archives and folk historical materials, combined with field research and oral interviews with overseas Chinese relatives, this paper sorts out the development of educational space, production space, public space, defense facilities, and living space during different stages of the overseas Chinese remittance industry's development. It further explores the reasons behind the evolution of village settlement space, aiming to provide reference for the development strategy of settlement preservation influenced by industry.
