For a long time, studies on the peer effect of physical activity among adolescents have focused on relevance rather than causality. This article provides empirical evidence of the peer effect of physical activity among adolescents using data from the China Education Panel Survey. The results show that the peer effect increases physical activity by about 6.757-8.984 min per week among classmates, a finding consistent with previous studies. Using the instrumental variable approach and considering the potential missing variables, the peer effect increases physical activity by 23.923-27.410 min per week, representing a threefold increase. In addition, the general attitude towards sports in class plays a significantly influential role, accounting for 20% of the peer effect of physical activity.
长期以来，青少年体育活动的同伴效应研究一直侧重于相关性而非因果关系。本文利用中国教育追踪调查数据，为青少年体育活动的同伴效应提供了经验证据。结果表明，同学之间的同伴效应对体育活动的影响约为每周增加 6.757-8.984 分钟，这一发现与以往的研究一致。使用工具变量法并考虑潜在的遗漏变量后，同伴效应对体育活动的影响每周增加 23.923-27.410 分钟，增加了两倍。此外，班级中对体育的总体态度也起着显著的影响作用，占体育活动同伴效应的 20%。
