Based on the experience of functional transformation of community-level social governance organizations, using the analysis methods of organizational decision making analysis school and related theories, this study fifi nds that the contingent governance of local government is an important driving force to promote the change of community-level social governance organizations. The change of community-level social governance organizations is not a process of natural realization according to the "ultimate goal" designed in advance, but a process in which local governments adjust their governance strategies and respond to the new challenges in institutional practice. This process is full of strategic action and construction of relevant actors. Based on the dual cognition of the community-level social governance organization reform, the local government constructs the goal of community-level social governance organization reform after weighing the different demands of different organizations. Through the way of contingent governance, it promotes the transformation of community-level social governance organizations from three aspects of governance structure, governance mechanism and governance orientation.
