The article substantiates the institutional prerequisites for the reproduction of the personnel potential of state and municipal authorities. It is emphasized that for local governments, which are actually a mechanism for the implementation of at least three major social and legal phenomena: firstly, municipal government, secondly, municipal service, and thirdly, municipal personnel policy. Particular attention is paid to the problems associated with the professional education of municipal personnel, their competence, necessary for the implementation of sustainable socio-economic development of municipalities and regions. This circumstance testifies to the demand for a competency-based approach to the training, assessment and professional development of managerial personnel in municipalities. The personnel potential of municipalities in the new Russia in the 21st century is the aggregate ability of the population to ensure in practice the adopted and updated strategies for sustainable socio-economic development of the territories of municipalities and, in fact, is one of the priority factors and the most important resource for staffing the executive administrative bodies of the municipal government. In this context, analyzing the quantitative and qualitative indicators of the personnel potential of local authorities, we believe that the quantitative characteristics mainly depend, firstly, on the demographic indicators of the municipality, within which the monitoring of personnel potential is carried out; Firstly, we note that the qualitative indicators are formed due to the well-established system of training and retraining of municipal employees according to the standards of the third generation in the universities of the region, in the Academy of National Economy and Public Administration under the President of the Russian Federation. However, as sociological research conducted by us in the Belgorod, Kursk, Lipetsk and Voronezh regions of the Central Federal District shows, the existing practice of regulating the vocational and educational structure of residents of local communities often still does not provide the required balance of personnel potential of municipal authorities and management. In the context of the formation and development of the digital economy, the requirements for the quality of training and activities of municipal personnel and persons in the managerial personnel reserve are significantly increasing, which necessitates the formation of preventive management decisions in the process of training and promotion of professionally trained personnel. Thus, we believe that the problem and relevance of our study is determined by the practice of the need to create evidence-based forms, methods and personnel technologies that ensure the achievement of strategic indicators of the socio-economic development of territories during the functioning, which to a large extent will allow solving this problematic problem. situation.
