Abstract: Through a set of top-down mobilization system of supervision and assessment,work leading group,village supervision of the village-stationed cadres,and policy publicity,the grass-roots campaign-style governance can operate effectively.Containing the paradox of control and anti-control,"constraint control" is the internal mechanism of the effective operation of grass-roots campaign-style governance.With the four control mechanisms of "authority-interest control" "authority-pressure control" "emotion-relationship control" and "procedure-rule control",constraint control makes grass-roots campaign-style governance simple,efficient and responsible.At the same time,three anti-control mechanisms of "communication adjustment-anti-control","soft constraint-anti-control" and "legal compliance-anti-control" are embedded in constraint control,so that grass-roots campaign-style governance presents the characteristics of moderate supply.Constraint control enables the infiltration of state power to achieve the dual unity of legitimacy and effectiveness,and changes the grass-roots power structure and relationship structure.The improvement of grass-roots campaign-style governance should start from two aspects of mechanism and system.In terms of mechanism,grass-roots campaign-style governance should construct the organizational control mode of constraint control,and in terms of system,our country should continue to strengthen the system construction of the administrative contract system.

Key words: campaign-style governance, mobilization, organizational control, constraint control, administrative contracting system
