This study examines the specific motivation of college students to volunteer, based on the interpretation of volunteering as entailing both consumption and investment. Analysis of micro-level data, collected in an online survey from non-volunteers and volunteers on the RenDa Economics Forum, one of the main social networking sites in China, and from volunteers at the Shanghai World Expo 2010 in China, provides strong support for consumption-related motivation. However, we find no clear statistical evidence for the validity of the investment motive. Volunteering activities are found to play no significant role in determining future income when compared to other factors, such as test scores, gender, age, parents’ education, job location, and the type of employer.
