This study examines the role of political efficacy and social networks in rural China to understand the social characteristics that might affect an individual’s disposition to join in public deliberations. A model is developed and empirically tested by Partial Least Squares analysis. This shows active involvement in public deliberation to be positively influenced by political efficacy (with external political efficacy being a partial mediator), high internal or external political efficacy, and a high internal efficacy leading to high external political efficacy. Social networks have a moderating effect, individuals with a high social network status having an enhanced positive internal political efficacy-public deliberation involvement but weakened positive external political efficacy-public deliberation involvement. The research advances the theoretical understanding of complex political psycho-behavior relationships and provided insights into the role of social settings. The findings could also help boost deliberative democracy in such limited democratic societies as China.
