Abstract: From the perspective of the development of Party building in social work institutions, this paper puts forward a mode of Party building, namely the postnate-exogenic empowerment mode. Based on “the Data of China Social Work Longitudinal Study in 2019” (CSWLS2019), the authors focus on the current situation and influencing factors of the establishment of the Party building departments in social work institutions, the party building manpower and Party building decisions. It is found that the coverage of Party building in social work institutions is not high. There is a lack of full-time personnel, and the frequency of organizational life is low. Further statistical analysis from the aspects of Party building departments, Party building personnel, and Party building decisions power shows that, first, social work institutions engaged in community services and rescue services are more likely to establish Party building departments. Second, the support (counterpart) funds and policy facilitation provided by the government will increase the possibility for social work institutions to establish Party building departments. The evaluation will increase the possibility for social work institutions to select full-time Party building personnel. Third, social work institutions in some fields have given full play to the role of Party building decisions. Accordingly, the future development of Party building in social work institutions should shift from postnate-exogenic type to starter endogenetic type, and highlight the leading role of Party building in professional services.

Key words: postnate-exogenic, social work institutions, Party building
