Based on data from the 2018 and 2020 China Longitudinal Aging Social Survey(CLASS), this study systematically investigates the impact of reemployment on older adults' participation in volunteer service, as well as the underlying mechanisms, using a Logit model and the Propensity Score Matching (PSM) method. The findings indicate that reemployment significantly promotes volunteer engagement of older adults, with high-frequency reemployment associated with increased frequency of volunteer participation. Mechanism analysis reveals that reemployment not only shapes positive psychological cues but also enhances the perception of social support, both of which promote elderly participation in volunteer service. Heterogeneity analysis shows that the positive impact of reemployment is more pronounced among older adults who reenter the workforce voluntarily, compared to those who do so passively. Further analysis indicates that reemployment among older adults has a stronger positive effect on participation in the informal type volunteer service than on participation in the formal type or dual-type volunteer service. To systematically activate the synergistic effects of reemployment and volunteer participation among older adults, it is recommended to remove participation barriers, reshape the societal recognition of “productive and joyful ageing”, and provide targeted incentive measures.

Using data from the 2000 and 2010 wave of Sample Survey of the Aged Population in Urban/Rural China, this paper analyzes trends and correlates of religiosity among Chinese elderly over 2000-2010 by performing period and cohort comparison and multiple logistic regression, in order to provide further evidence for aging policies in China. Results show that the proportion of elderly having religiosity declined from 15.56% in 2000 to 13.89% in 2010; and this proportion of religiosity among the elderly was decreasing in the same age group over time, and decreasing with age in the same birth cohort, which is consistent with the prediction of secularization theory. Gender, ethnicity, education, party membership/cadre status, chronic disease, self-rated filial piety, living with children, and participations in social organization have significant impact on religiosity among the Chinese elderly.
