社会资本理论视角下数字素养对老年人健康的影响——基于CHARLS 2015~2020面板数据的分析

The Impact of Digital Literacy on the Health of Older Adults from the Perspective of Social Capital Theory—An Analysis Based on CHARLS 2015~2020 Panel Data

摘要: 老龄化加剧使老年数字社会资本缺失成为健康老龄化重要障碍。本文基于CHARLS2015~2020数据，依托社会资本理论构建传导框架，实证检验数字素养对老年人健康的影响。结果表明：数字素养可显著提升老年健康水平，且在低支持–低健康行为群体中边际效应最强，高支持群体仅获增量优化；城乡与教育存在调节作用，农村数字接入不足与教育差异制约健康收益释放。

Abstract: Against the intensifying aging, the lack of digital social capital among the elderly has become a major barrier to healthy aging. Based on CHARLS 2015~2020 data and social capital theory, this paper empirically examines the impact of digital literacy on the health of the elderly. The results show that digital literacy significantly improves the health of the elderly, with the strongest marginal effect in the low-support and low-health behavior group, while the high-support group only achieves incremental optimization. Urban-rural and educational factors play moderating roles, and insufficient rural digital access and educational differences restrict the release of health benefits.
