Abstract: Currently, China's urban development has entered a stage of upgrading existing stock to improve quality and efficiency. The renovation of community public spaces serves as a crucial approach to enhancing urban quality and advancing grassroots governance. However, in practice, issues such as closed action goals, shortterm interest arrangements, rigid role allocation, and the disconnection between spatial functions still constrain renovation effectiveness. Based on Actor-Network Theory (ANT), this study takes the renovation of Donghu Dakeng in Shantou, Guangdong as a case study and employs the single-case process tracing method to examine the key driving mechanisms underlying the occurrence and continuation of actor translation in community public space renovations. The findings reveal that the translation in the Donghu Dakeng renovation is not the result of a natural assemblage of heterogeneous actors, but rather a relational network gradually generated through four mechanisms: consensus building, interest coordination, role embedding, and space empowerment. These four mechanisms respectively promote the generation of public issues, the coordination of diverse interests, the assumption of action responsibilities, and the continuous mobilization of built spaces, thereby integrating illegal structure demolition and pollution remediation, landscape construction, and subsequent management and maintenance into a unified action network. This study concretizes the abstract translation process in ANT into observable grassroots governance mechanisms, and reveals the continuous role of public spaces as non-human actors in network maintenance.
