Abstract:Rural digital governance is the core driving force to promote the modernization of China's governance level, and the embeddedness of social think tanks promotes the smooth delivery of digital resources and the cultivation of endogenous forces in the countryside, and promotes the synergistic resonance of all parties. Based on the theory of synergistic governance, the three functions of social think tanks' participation in rural digital governance, namely, consultative politics and social aid, multi-disciplinary talent research and social capital intervention were discussed. In terms of structure and relationship, and the dual dilemmas of inability to deeply embed internal and external structures and the limitations of linkage between different subjects was discovered. It is necessary to reshape the development path of social think tanks and to strengthen the recognition and interaction of social think tanks among various subjects.
