Chinese Intangible cultural heritage is an important vehicle for demonstrating China’s cultural soft power. Adopting methods such as literature research method and field investigation, and taking ShiSuo Sport as a case study, this research explores the longitudinal historica linheritance context and the horizontal social network extension logicinvolved in the transmission of ShiSuo Sport as intangible cultural heritage, based on Actor-Network Theory. The findings show that, rooted in agrarian civilization, the ShiSuo sport has undergone stages of development including emergence, disappearance, and revitalization, and has exhibited a trend of high-quality development along the longitudinal temporal dimension. Horizontally, it has formed a law and policy-oriented, core actor-centered concentric-circle structure of inheritance and development that expands layer by layer from the inside out, namely: core actors, active actors, auxiliary actors, and potential actors, with the outer two layersof inheritors undergoing dynamic transformation.. On this basis, practical implications are proposed to promote the high-quality development of ShiSuo Sport.
