Abstract: The advancement of National Sports Tourism Demonstration Zones serves as a pivotal measure to deepen the integration of sports and tourism industries, address national strategic needs, and drive high-quality development in sports tourism. From a value co-creation perspective, this study employs literature research, interviews, and case studies to construct an analytical framework centered on “value consensus, value symbiosis, and value diffusion”. Through a comparative examination of cases in Guangxi, Hainan, Chongqing, and Guizhou, it identifies representative experiential practices and proposes actionable pathways. Findings indicate that while variations exist in development objectives, implementation routes, and service offerings across different zones, each emphasizes the positive roles of multi-stakeholder engagement, innovative resource utilization, collaborative value creation, and policy-guided planning. To further promote the development of these zones, it is essential to strengthen value consensus, foster value symbiosis, and accelerate value diffusion. This can be realized by establishing a collaborative cognition system involving diverse stakeholders, creating integrated environments for holistic resource convergence, and amplifying the demonstrative impact of advanced practices within the sports tourism sector.
