运用文献研究法、逻辑分析法等研究方法，探析青年与人工智能协同建设中国式现代化体育的作用机制与面临的现实挑战，并提出关键驱动路径。基于协同创新理论，经分析发现，人工智能技术赋能机制、场景应用机制、参与创新机制、价值共创机制共同构成青年与人工智能协同建设中国式现代化体育的作用机制。然而，在实际推进中面临着重重现实挑战，包括数据治理失范引发的隐私泄露与伦理风险、算法偏差强化的结构性不均等、青年过度依赖人工智能技术会消解其主体性以及使其认知能力退化、互联网体育服务的适应性困境与参与人群代际失衡。基于此，提出4条关键驱动路径：1）对制度进行适应性调试，完善数字技术治理体育框架与健全青年创新机制；2）增强体育教学的数智化韧性，重构新时代体育专业青年的认知路径；3）构建政府、体育社会组织、青年多主体联动机制，协同营造体育人工智能创新环境；4）加强数据基础设施建设，筑牢青年与体育人工智能协同创新的安全基座。

Using research methods such as literature analysis and logical reasoning, this study explores the mechanisms and practical challenges of how youth and artificial intelligence collaboratively develop Chinese sports modernization, Chinese, and proposes digital technology-driven pathways. Based on the theory of collaborative innovation, the study finds that the mechanisms of AI technology empowerment, scenario application, participatory innovation, and value cocreation collectively constitute the operational mechanism for youth andAI to collaboratively develop Chinese sports modernization. However, in practical implementation, challengesinclude: privacy leakage and ethical risks caused by problematic data governance, structural inequalities reinforced by algorithmic bias, the erosion of youth subjectivity and the decline of their cognitive capacities due to overreliance on AI technology, as well as the adaptive challenges of internet-based sports services and intergenerational imbalance among participants. Based on these findings, the study proposes four key technology-driven pathways: first, adaptive adjustment of institutions， improvement of the sports governance framework under digital technology, and improvement of youth innovation mechanisms; second, strengthening the digital intelligence resilience of sports education to reshape the cognitive pathways of sports-major youth in the new era of 21st century; third, establishing a multi-stakeholder linkage mechanism involving governments, sports social organizations, and youth and collaboratively creating an innovative environment for sports AI; fourth, strengthening the construction of data infrastructure to consolidate the security foundation for the collaborative innovation of youth and sports AI.
