研究目标：基于福利经济学和阿马蒂亚·森的可行能力理论构建个体福利指标体系，来检验体 育参与对个体福利提升的作用和效应以及社会资本的中介作用。研究方法：利用中国家庭追踪调查数 据库（CFPS）的微观数据，运用多元线性回归模型和 KHB中介效应检验法和可视化进行实证分析。研究 结论：体育参与不仅可以提升个体总福利水平，还可以提升分维度福利水平；社会资本在体育参与影响 个体福利的过程中发挥中介作用，其中，个体社会资本对健康和幸福感维度的福利提升作用较大，集体 社会资本对教育和收入维度的福利提升作用较大。研究创新：揭示了体育参与通过社会资本对个体福 利提升的影响机理。研究价值：为进一步促进全民健身、实施健康中国战略提供理论支撑。

Based on welfare economics and Amartya Sen’ s capability approach， this study constructs an individual welfare indicator system to examine the role and effects of sports participation in enhancing individual welfare， along with the mediating role of social capital. Utilizing micro-data from the China Family Panel Studies（CFPS）， empirical analyses are conducted using multiple linear regression models， the Karlson-Holm-Breen（KHB）mediation effect test， and visualization techniques. The results suggest that sports participation not only elevates the overall welfare level of individuals but also enhances welfare across specific dimensions. Social capital serves as a mediator in the process， with individual social capital has a greater effect on health and well-being， while collective social capital has a greater effect on education and income. This study reveals the mechanisms through which sports participation influences individual welfare enhancement via social capital and provides theoretical support for furthering nationwide fitness initiatives and implementing the Healthy China strategy in the new era.
