Abstract: This paper examines the place-making and supply of public cultural spaces in borderland small towns within the context of slow city construction, drawing on three years of practice of the ‘Shandu' cultural brand in Alxa League, Inner Mongolia. Rather than treating cultural supply as a matter of facility distribution alone, the study builds on Lefebvre's theory of spatial production and insights from place-making scholarship to propose a five-dimensional supply framework-slow ecology, slow space, slow culture, slow life, and slow governancewhich corresponds to the economic, social, ecological, spatial, and governance dimensions of urban development. This framework is then used to analyze how a region characterized by vast territory, sparse population, and multiethnic settlement innovates its cultural delivery. What sets Alxa apart from slow cities in eastern China is its desert landscape-the Badain Jaran Desert, the Ejina Populus euphratica forest, and the Tengger Desert together form a unique core attraction. Evidence from the case shows that through layered composite spaces, embedded cultural markets, the excavation of local heritage, and the extension of digital services to community level, the ‘Shandu' brand has achieved a shift from a logic of ‘facility coverage' to one of ‘brand penetration'-even under extreme geographical constraints-with service efficiency improving markedly in the process. At the same time, the brand still faces sustainability challenges, including a shortage of professional staff, activity homogenization, and operational frictions arising from competing uses of space that the current model has yet to fully resolve.
