青少年体育高质量发展既是加快建设体育强国、教育强国与健康中国的基础工程，也是实现中华民族伟大复兴战略目标的重要支撑。基于系统论视角，构建“要素-结构-功能”分析框架，揭示了青少年体育高质量发展是要素配置优质化、结构运转高效化、功能实现增效化的动态演进过程。研究表明，我国青少年体育当前发展面临的系统困境是：在要素层面，人力、物力、财力、知识技能等资源配置失衡；在结构层面，政策执行碎片化、体教融合浅层化、多元主体协同不畅、科学评价体系缺乏等治理问题凸显；在功能层面，个体素养提升受限、社会价值存在认知偏差、后备人才培养乏力等引致整体效能衰减。基于此，提出优化要素资源配置以夯实系统发展基础、创新结构协同机制以提升系统运转效率、促进功能价值实现以释放系统整体效能等突破路径。

Promoting the high-quality development of youth sports is a foundational project for accelerating the construction of a strong sports nation, a robust education system, and a Healthy China, as well as a crucial pillar in achieving the strategic goal of national rejuvenation. From a systems theory perspective, an “element-structure-function” analytical framework reveals that the high-quality development of youth sports is a dynamic evolutionary process characterized by optimized resource allocation, efficient structural operation, and enhanced functional performance. The study ide.jpgies systemic challenges in China’s current youth sports development: at the element level, imbalanced resource allocation in human, material, financial, and knowledge-skill resources; at the structural level, bottlenecks such as fragmented policy implementation, superficial integration of sports and education, weak coordination among diverse stakeholders, and a lack of scie.jpgic evaluation systems; and at the functional level, constrained individual competence enhancement, biased social value perception, and inadequate training of national reserve talents, all leading to overall efficacy decline. To address these issues, breakthrough pathways are proposed, including optimizing resource allocation to strengthen the foundation of system development, innovating structural coordination mechanisms to enhance operational efficiency, and reinforcing functional value realization to unleash the system’s overall efficacy.
