Abstract:At present,the problematic villages in rural areas have brought enormous challenges to the domestic grassroots governance. Under this premise,A County in North China innovated the System of Assigned Party Secretary and achieved good practical results. Under the coordination of the Organization Department of the County Party Committee,the county and villages jointly built a talent pool and then assigned the appropriate cadre to resume the party secretary of the problematic village to realize the precise match between talents and villages. In the actual governance process,the assigned party secretary realized the effective governance of the problematic village by constructing the integration mechanism of village power,the mobilization mechanism of governance resources,and the flat governance mechanism for dealing with trivial matters.The System of Assigned Party Secretary is a decisive step for the party-led grassroots governance,providing the direction for the building of grassroots governance ability.
