Abstract:As an “event” that deeps into the local community,the precision poverty alleviation triggers the conflict between the state power and local society. There are obvious information asymmetries between the digitalized governance technology and the ambiguity of the rural society,divergences between formal state power and the rural endogenous orders,differences between the logic of distinguishment and the egalitarianism adhered by the ordinary farmers.In the face of these conflicts,the villages and farmers,in the process of the precision poverty alleviation,create the system of villagers’ comments to construct the joint governance. The result shows that the joint governance of farmers’ comments mainly include the following governance mechanisms:information mechanism benefited from acquaintance society,authority mechanism constructed by multiple participation and consensus mechanism constructed by consultative discussion. As a result,this system creates a new institutional arena,which is useful to combine the state power with local society. Based on the case study of B village in the west of Hunan province,this paper explores its governance mechanism and perfect its deficiencies,which can provide some enlightenments to precision poverty alleviation and landing of public policy at the grassroots level so as to achieve changes from the joints-separation to the joints-fusion and the effective governance in the grass-root society.
