The widespread use of the Internet has increased re-employment opportunities for the younger senior population. Utilizing data from the 2020 China Health and Retirement Longitudinal Study, this research employs a Logit model for baseline regression to explore the impact of Internet use on re-employment among younger seniors. Findings of this study indicate that Internet use signifi cantly promotes the re-employment among younger seniors; the effects vary across different subgroups, with those having an elementary education or being married more likely to be infl uenced by Internet use, thus having a higher probability of re-employment. Mechanism analysis shows that the Internet enriches younger seniors' social capital by enhancing social activities, thereby facilitating their re-employment. The study suggests that it is advisable to cultivate the ability of younger seniors to use the Internet, leveraging its inclusivity and role as a medium of communication to provide them with a wealth of social activities, thereby promoting their re-employment.
