Government-founded social organizations are a social governance  innovation model with Chinese characteristics, reflecting a profound  restructuring of the relationship between the state and society. The  Chinese government is rapidly founding various community foundations, among which there are obvious differences in the functional positioning  and operational mechanisms of government-led community foundations. With the help of fs/QCA 3.0 software, a qualitative comparative analysis of  the fuzzy set of 19 typical cases reveals that the causes of these  differences are not single, but a complex result of a combination of  multiple factors. In this regard, five explanatory models were constructed: development-led, issue-derived, resource mobilization, community  creation, and policy mobilization. Among them, the "policy mobilization  type" accounts for the largest share and tends to cultivate social  organizations and build public welfare platforms as organizational goals, which is consistent with the policy goals and preferences of the Chinese  government in governance innovation.
