Relevance. The problem of ensuring economic resilience of single-industry municipalities (monotowns) remains acute for many Russian regions, including the Republic of Dagestan. While being significant industrial centers, monotowns simultaneously concentrate key socio-economic risks: high dependence on a single industry, structural unemployment, and low budgetary capacity. A comprehensive assessment of their condition and integration into the regional economy is necessary for developing effective public policy measures aimed at mitigating structural imbalances and stimulating diversification. Purpose. To assess the economic resilience of monotowns in the Republic of Dagestan, identify their key problems and systemic risks within the context of the region's socio-economic development, and determine promising directions for enhancing their sustainability. Methodology. The research is based on the application of comparative, structural, and dynamic analysis methods. The information base includes official statistics (the «Dagestan in Figures — 2024» compendium), federal and regional registers of monotowns (VEB.RF), and reports from ministries of the Republic of Dagestan for the period 2019—2023. Results and Conclusions. The study establishes that the monotowns of Dagestan (Kaspiysk, Dagestanskiye Ogni, Izberbash, etc.), while generating about 18—20 % of the republic's GRP, act as local centers of socio-economic vulnerability. Systemic problems were identified: the unemployment rate is 3—4 times higher than the Russian average, the share of the population in poverty reaches 17—18 %, and budgetary capacity is 15—25 % lower than the republican average. Key resilience risks are associated with single-industry dependence and insufficient economic diversification. It is concluded that a transition from targeted support to a comprehensive strategy for transforming monotowns into multifunctional centers is necessary, involving the development of tourism-service, logistics, and creative clusters. Practical significance. The research results can be used by state and municipal authorities in developing and adjusting strategies and programs for the socio-economic development of single-industry territories.
