Abstract: County jurisdictions constitute the frontline where the Party's social work is implemented and represent the pivotal level for effective execution of departmental functional adjustments.Since assuming full operation,social work departments across Yunnan Province have consistently adhered to a standardized procedure comprising "field visits,public consultation,and training programs" in accordance with national strategic priorities.By focusing on critical issues in community-level governance,these departments have developed an institutional framework and operational model characterized by "policy coordination as the anchor" and "assimilation of exemplary practices as the foundation",demonstrating significant universal applicability.Currently,operational efficiency faces two major constraints:horizontally,ambiguous functional boundaries with parallel Party and government agencies,and vertically,misaligned articulation with township (sub-district) level institutions.To enhance departmental efficacy,it is imperative to establish an integrated county-township social work mechanism featuring "vertical integration,clarify functional divisions and operational boundaries between social work departments and relevant Party and government agencies,and eliminate structural impediments.Guided by Party building principles,a comprehensive "Big Social Work" framework should be advanced through a combined approach of socialization,professionalization,informatization,and marketization,thereby refining this distinctive Chinese system through practice.Furthermore,identifying effective intervention points to address pressing public concerns,while strengthening consultative and service-oriented governance capacities,will systematically enhance the credibility of social work departments.
