Abstract: Based on the practice of digital government, the core mechanism of digital faciliation could be defined as two-way activation. On the one hand, by connecting the demands in the front end and the back end of grass-roots governance, the digital technology pours the multiple demands of civil servants, enterprises and the public into the whole chain of grass-roots governance process. It organizes the grass-roots governance from start to finish and activates the government accurately and efficiently in grass-roots governance. On the other hand, by regrouping the resources inside and outside the organization, the digital technology reorganizes the scattered social forces, such as the party builders, social organizations, the administration and the market, and the idle social resources to activate the social vitality. The two-way activation, in essence, uses digital technology to facilitate the two key links of discovering and solving social problems and promote the grass-roots governance.
