研究探讨受教育程度、数字文化资本（互联网使用）与体育锻炼参与之间的因果中介关系。基于布迪厄的文化资本理论，使用中国综合社会调查（CGSS）数据，运用工具变量回归和IV—因果中介效应模型进行分析。研究发现：①受教育程度与体育锻炼参与度显著相关，表明教育作为文化资本提升个体健康行为的能力；②数字文化资本（互联网使用水平）在受教育程度影响体育锻炼参与中起中介作用，反映数字时代文化资本的新内涵及其对健康行为的影响；③父母的受教育程度通过子代的受教育程度和数字文化资本传递影响其体育锻炼行为，深入揭示了文化资本在家庭中的代际传递机制。丰富文化资本理论在健康行为研究中的应用，揭示数字时代教育影响健康行为的新机制，深化对体育锻炼参与差异代际传递的理解。研究结果对促进全民健身具有重要的政策启示作用，强调提高受教育程度、提升数字文化资本和关注家庭教育环境在增进公众体育锻炼参与中的重要性。研究为理解健康中国战略背景下受教育程度、数字文化资本与体育锻炼参与之间的关系提供新的实证证据，为制定针对性的全民健身促进政策提供科学依据。

This study investigates the causal mediation relationship among educational attainment，digital cultural capital （internet use level），and physical exercise participation. Based on Bourdieu’s cultural capital theory，we use data from the Chinese General Social Survey （CGSS） and employ instrumental variable regression and IV-mediation effect models for analysis. The findings reveal：① Educational attainment is significantly associated with the level of participation in physical exercise，demonstrating that education，as a form of cultural capital，enhances individuals’ capacity for healthy behaviors； ② Digital cultural capital （Internet use level） mediates the effect of educational attainment on participation in physical exercise，reflecting new connotations of cultural capital in the digital age and its impact on healthy behaviors； ③ Parents’ educational attainment influences their children’s physical exercise behavior through the transmission of their children’s educational attainment and digital cultural capital，deeply revealing the intergenerational transmission mechanism of cultural capital within families. These findings not only enrich the application of cultural capital theory in healthy behavior research but also uncover new mechanisms through which education influences health behaviors in the digital era，deepening our understanding of the intergenerational transmission of disparities in physical exercise participation. The results have important policy implications for promoting nationwide fitness，emphasizing the significance of improving educational attainment，enhancing digital cultural capital，and focusing on family educational environments in enhancing public participation in physical exercise. This study provides new empirical evidence for understanding the relationship among educational attainment，digital cultural capital，and participation in physical exercise within the context of the Healthy China strategy，offering a scientific basis for formulating targeted policies to promote public health.
