Existing research on the agglomeration effect of urban roads mainly focuses on land use but ignores the differences between various locations, types, and directions of roads. Few studies have been conducted on the built buildings which can represent the actual utility, and land use as a kind of government authorization may not necessarily represent actual needs. This research provides an analytical framework and an empirical analysis to study the differences in impacts of different urban roads on land use and to identify its internal dynamic mechanism. Guangzhou, being the research object, is one of the five major central cities in China. By using the techniques of GIS and SPSS, together with the methods of corridor effect, correlation analysis, and geographic detector, we analyze the external characteristics of office buildings and land gathering along both sides of the roads, explore the urban characteristics of corridor effect, then analyze the relationship with urban traffic flow and bus network density in order to find out the internal motivation of corridor effect. The fundamental conclusion can be drawn that the corridor effect on the land used for commercial offices is mostly unnoticeable, and roads of different locations, types, and directions display various scope and intensity of corridor effects. The agglomeration power is mainly caused by private transportation and has no relationship with public transport. The article concludes the model of the corridor effect and provides some policy suggestions to the government in order to strengthen the linkage development of transportation and land and to promote the improvement of land use efficiency.

The micro-renewal of rural heritage in urban villages transcends spatial transformation, profoundly altering social structures and relational dynamics. Recent research has emerged concerning the cultural impact of rural revitalization on rural heritage. However, little research has been undertaken regarding the specific mechanisms via which various renewal orientations influence the community. This study focuses on the case of Whampoa Village in Guangzhou, China, specifically highlighting the rehabilitation of its ancestral temples. Utilizing a field–space–society analytical framework, it analyzes how these revitalized ancestral temples enhance community resilience and instigate a reverse reconfiguration of spaces. Moreover, it emphasizes that the varied rehabilitation approach of ancestral temples, by including different social groups, fosters the establishment of new community connections. NGOs and small investors act as the primary catalysts for the preservation and inheritance of cultural heritage. The redevelopment initiative in Whampoa Village has enhanced spatial diversity, thereby reinforcing and transforming existing community structures. Nonetheless, it highlights the potential for spatial inequities arising from capital-driven commercialization in these rural regions. This article seeks to enrich the global database of cultural heritage by including cases from southern China and to contribute to the literature on the preservation of rural cultural assets.
