The reform of grass-roots governance is a process of re-framing government’s mechanism to continuously respond to residents’ demands and solve governance problems. Beijing has built a more effective grassroots governance system in the capital through deepening the reform of “Sub-district Offices And Township Governments Whistle，Agencies Report for Duty” and the Reform of Immediate Action on Request，which creates a highly organized and institutionalized model of aggregated response governance driven by the top of government. The reform focuses on the problems which originate from urban governance and the public，realizes a regular link between government and society by empowering the grass-roots government and upgrading the citizen service hotline platform，and enhances the response dynamics of grass-roots government greatly. Meanwhile，it improves the basic responsive capacity of the grass-roots government effectively by giving full play to the role of party construction，modern digital technology and social coordination. Compared with the traditional stimulus-passive response governance，the reform reflects the significant features of active governance，systematic governance，legal governance，comprehensive governance and source governance.
