This study explores how online community managers can encourage prosocial behaviors through small group interactions, integrating social exchange theory with group influence theory. It investigates the impact of reputation and reciprocity on user contributions under different group influences, using longitudinal data from over 3,000 members across 72 subgroups. The findings offer insights for administrators to enhance knowledge contribution and exchange within online communities.
