Against the backdrop of the convergent development of the digital economy and the sports event economy, and in response to the new requirements for the high-quality development of China’s professional sports leagues during the 15th Five-Year Plan period, the reshaping of consumption scenes has become a pivotal entry point for unlocking the leagues’ composite value. Drawing on Collins’s interaction ritual chain theory, this study examine the ritual elements, driving forces, consumption conversion mechanisms, and migration mechanisms involved in the reshaping of consumption scenes in professional sports leagues. The findings show that offline consumption scenes are characterized by physical co-presence, symbolic boundaries, overlapping foci of attention, and graded interactional rhythms, whereas online consumption scenes reconstruct ritual interaction through virtual co-presence, multiple symbolic barriers to participation, focal differentiation, and affective synchronization through real-time bullet-screen comments. The reshaping of consumption scenes is jointly driven by the endogenous driving force of emotional attachment, the identity performance of symbolic capital, the ritual transformation generated by collective effervescence, and the multiplier effect of fan communities. These dynamics are translated into consumer behavior through three pathways-emotional response, identity identification, and moral objectification-while online and offline rituals form an interconnected, symbiotic ritual network through a closed loop of accumulation, realization, and archiving. The study further identifies persistent constraints, including participation stratification, emotional fragmentation, consumption conversion bottlenecks, and weak continuity across scenes. Accordingly, it proposes practical strategies centered on tiered fan participation, full-cycle content operation, service-chain integration, and cross-platform coordination.
