Abstract: Deliberative democracy, as it is put on the agenda by the Party and the State, at the grassroots level has developed diffusely-formal recognition, improved system, improved procedural mechanism, more diverse forms and richer topics, with a prospect that has rendered positive governance efficiency, i.e. cultivating the social spirit of consultation and dialogue, alleviating the social conflicts at the grass-roots level, relieving the governance pressure for the Party and the State, reconciling the diversified social values, integrating the scattered personal knowledge, and reshaping the system of governance at the grass-roots level. The development of such attributes to multiple factors, mainly, for achieving governance efficiency, the flexible adaptive mechanism. Such mechanism is embodied in the unity of centralized leadership and decentralized exploration, the integration of formal system and informal system, the complementarity of electoral democracy and deliberative democracy, and the coupling of traditional value and modern consciousness. Such a conclusion not only shows how the diffuse development of grassroots deliberative democracy is realized, but also explains how such democracy is transformed into governance efficiency.

Key words: flexible adaptability, grassroots deliberative democracy, diffuse development, governance efficiency, grassroots governance, electoral democracy
