Abstract: Efficient and flexible social mobilization is an important prerequisite for stimulating the realization of multiple values of mega sporting events. Therefore, it is of great significance to construct a reasonable and effective mobilization framework for sporting events by analyzing the information flow and internal law of multiple-type mobilization issues of sporting events in social communication, in order to promote the value-carrying and social cohesion capacity of mega sporting events in China. By selecting four mega sporting events between 2021 and 2023 as the research objects, the study uses complex network modeling to differentiate the network structure and distribution effects of different types of mobilization issues in the four dimensions of scale, breadth, depth and time of dissemination. It finds that at this stage, the horizontal dissemination effect of national emotion and cultural attribute issues is the most significant, the deepening mobilization ability of athletic attribute issues is more prominent, and the entertainment attribute issues present an overall balanced dissemination effect. Then, the practical pathways for constructing the social mobilization pattern of mega sporting events in China are proposed from three aspects: the dynamic adjustment of the mobilization structure layout, the adaptive guidance of the common intention mobilization and the adaptive debugging of the rational mobilization.
