BACKGROUND: Health is the cornerstone of individual well-being and a vital factor in socioeconomic development. In an increasingly digitalized world, digital literacy has emerged as one of the indispensable abilities, which not only pertains to an individual's capacity to acquire, analyze, evaluate, and utilize information but also profoundly influences their health behaviours, health decisions, and overall well-being. This paper uses the 2020 China Family Panel Studies (CFPS) data to explore digital literacy's impact on individuals' health.
METHODS: By using the Entropy-TOPSIS method, this paper calculates digital literacy as a three-dimensional construct and adopts Ordered Probit and OLS models to analyze the impact of digital literacy on physical and mental health. Additionally, this paper employs the Two-Stage Least Squares (2SLS) to address endogeneity issues. The indirect effects of income, employment quality, and informal social support on individual's digital literacy and health nexus are also examined by the mediation effect model.
RESULTS: The results indicate that digital literacy positively impacts individuals' physical and mental health, which was confirmed by several robustness tests. The heterogeneity analysis shows that digital literacy is more effective in enhancing the health of middle-aged and older groups as well as rural individuals in China. According to mechanism analysis, digital literacy can enhance individuals' health by boosting income, improving employment quality, and expanding informal social support; however, the effects vary on physical and mental health.
CONCLUSION: Several policy suggestions emanate from the findings. To enhance the positive impact of digital literacy on individuals' health, the policy makers should emphasize on enhancing digital literacy particularly in rural areas and older age groups, bridging the digital divide, refining employment services and embracing a healthy concept of online social networking.
