The Impact of CPC Membership on Subjective Well-Being: The Mediating Role of Volunteer Service Participation

This study explores the impact of CPC party membership on subjective well-being, using data from the 2021 "Chinese Social Survey". The analysis was conducted using an OLS linear regression model and the Bootstrap method. The results indicate that party membership significantly enhances an individual's subjective well-being, primarily through increased sense of identity and collective belonging. Participation in volunteer service acts as a mediator between party membership and subjective well-being, with party members gaining a sense of achievement and social support through volunteer activities, which further boosts their well-being. The study also finds that factors such as social support, economic status, and life satisfaction significantly influence subjective well-being.
