The article defines that public administration is a system of activities of state authorities aimed at optimizing the use of resources to achieve the priority goals of social policy. It is emphasized that the social sphere covers a wide range of services that ensure the well-being of citizens, including health care, education, social protection and other critically important elements. The study of the problems of public management of the social sphere in territorial communities reveals a number of challenges, such as insufficient financial support, the absence of a clear legal framework, and a low level of public involvement in decision-making processes. Analysis of modern approaches to legal regulation in this area showed that effective management of social policy requires the integration of innovative methods, in particular digitalization of processes, which will contribute to the transparency and accountability of local self-government bodies. As a result of the research, it was found that the public management of the social sphere in the territorial communities of Ukraine is a complex, multifaceted process that requires a comprehensive analysis and a comprehensive approach to its improvement. The development of recommendations for improving management mechanisms should become a priority for researchers and practitioners in this important field. Effective management of the social sphere requires systematic control over the implementation of state policy. This involves not only an internal audit of the activities of local self-government bodies, but also mechanisms of public control that would allow residents to actively participate in the processes of evaluating the effectiveness of social programs. The study showed that the key factors in the effectiveness of public management of the social sphere in territorial communities are: adaptability of management mechanisms; integration of modern technologies; formation of partnership relations; personnel training and development; community involvement in decision-making processes, etc. Legal regulation of public management of the social sphere in territorial communities of Ukraine is conditioned by the need to create effective management mechanisms that meet modern challenges. Among the prospects for the development of legal regulation of public management of the social sphere in the territorial communities of Ukraine, the need for: improvement of the legal framework was emphasized; strengthening of financial autonomy; development of professional training; integration of modern technologies; community involvement in decision-making processes; focus on inclusiveness; monitoring and evaluation of efficiency; cooperation with international organizations; adaptation to changes in the socio-economic environment; increasing the level of trust in the authorities, etc. It is emphasized that the successful implementation of public policy in the social sphere depends on the effective interaction of all interested parties, which in turn will ensure sustainable development and increase the quality of life of the population.
