基于CGSS2005、CGSS2015两期截面数据，运用logistic回归模型分析了中国居民体育参与的变化 趋势及其影响因素，结果显示：（1）2005-2015年间，居民体育参与率显著提高，体育参与的群体异质性与阶 层分化现象日益凸显；（2）传统社会分层变量对体育参与的影响呈现多样化特征：随着时间推移，个人受教 育程度对体育参与的促进作用递增，职业分层的影响依旧显著，而收入对体育的促进作用不断减弱；（3）家 庭社会经济地位的影响力在不断削弱，取而代之的是家庭教育资本的作用不断增强。因此，要关注体育参 与群体异质性扩大化倾向。建议通过优化政策，降低结构性因素导致的体育参与不均衡问题，提高弱势群 体的体育参与率。

Based on the cross-sectional data of CGSS2005 and cgss2015，this paper uses logistic regression model to analyze the change trend and influencing factors of sports participation of Chinese residents.The results show that：（1）during 2005-2015，the rate of residents’sports participation has increased significantly，and the phenomenon of group heterogeneity and level differentiation of sports participation has become increasingly prominent；（2）the influence of variables of traditional social stratification on sports participation has been presented diversification characteristics：with the passage of time，the promotion of individual education level on sports participation is increasing，the influence of professional stratification is still significant，and the promotion of income on sports is weakening；（3）the influence of family socio-economic status is weakening，and the role of family education capital is increasing. Therefore，we should pay attention to the tendency of sports participation group heterogeneity expansion.It is suggested to optimize policies to reduce the imbalance of sports participation caused by structural factors and improve the participation rate of vulnerable groups.
