Supplementary file 1_The impact of digital literacy on rural residents' sports participation behavior:evidence from China.docx

PurposeInsufficient Digital Literacy among residents may lead to a polarization in access to digital resources, thereby affecting their willingness to participate in exercise, which necessitates attention. This study aims to analyze the impact of Digital Literacy on sports participation behavior from the perspective of internet perception, along with its potential mechanisms, providing a basis for promoting healthy lifestyles and enhancing public health service levels in rural areas.
MethodsBased on the mixed cross-sectional survey data from the China family panel studies (CFPS) conducted in 2018, 2020, and 2022, a comprehensive analysis was performed using binary logistic regression, Heckman two-stage regression, instrumental variable methods, and Karson-Holm-Breen (KHB) mediation effects to examine the impact of Digital Literacy on sports participation behavior among rural residents and its underlying mechanisms.
ResultsThis study found that Digital Literacy significantly enhances the level of sports participation behavior among rural residents, with results remaining reliable after a series of robustness checks. Furthermore, the mechanism analysis indicates that Digital Literacy can indirectly enhance the level of sports participation behavior by stimulating digital usage behaviors among rural residents, promoting human capital accumulation, and increasing social capital levels. According to the heterogeneity analysis results, male, middle-aged, and married rural residents exhibit higher levels of Digital Literacy and are more inclined to participate in sports activities.
ConclusionAs the Digital Literacy level of rural residents improves, a deeper understanding of the multidimensional value of physical exercise is attained, thereby promoting their active participation. Mechanisms related to digital usage behavior, human capital accumulation, and social capital levels play a more significant role in facilitating physical exercise. To accelerate the construction of digital villages, it is imperative to increase investments in rural digital education to address the challenges faced by residents in utilizing internet technology and devices, thereby facilitating better integration into an information society and fulfilling the demands of rural communities for physical exercise and healthy living.

一、研究背景与目的
居民数字素养（Digital Literacy）不足可能引发数字资源获取的极化现象，进而影响其参与体育锻炼的意愿，这一问题亟待关注。本研究旨在从网络感知视角，剖析数字素养对农村居民体育参与行为的影响及其潜在作用机制，为推广健康生活方式、提升农村公共卫生服务水平提供依据。
二、研究方法
本研究基于2018、2020及2022年中国家庭追踪调查（China Family Panel Studies, CFPS）的混合截面调查数据，采用二元Logistic回归、Heckman两阶段回归、工具变量法以及Karson-Holm-Breen（KHB）中介效应分析法开展综合分析，以检验数字素养对农村居民体育参与行为的影响及其内在作用机制。
三、研究结果
本研究发现，数字素养可显著提升农村居民的体育参与水平，该结论在一系列稳健性检验后依然可靠。进一步的机制分析表明，数字素养可通过激发农村居民的数字使用行为、促进人力资本积累以及提升社会资本水平，间接增强其体育参与程度。异质性分析结果显示，男性、中年以及已婚农村居民的数字素养水平更高，且更倾向于参与体育活动。
四、研究结论
随着农村居民数字素养水平的提升，其对体育锻炼多维价值的认知将更为深入，进而推动其主动参与体育活动。与数字使用行为、人力资本积累及社会资本水平相关的作用机制，对促进体育锻炼发挥了更为显著的推动作用。为加快数字乡村建设，亟需加大农村数字教育投入，以解决居民在使用互联网技术与设备时面临的困境，助力其更好地融入信息社会，满足农村社区居民的体育锻炼与健康生活需求。
