摘要：The need for sustainable development of regional economies and the energy sector in the context of world economy deglobalization is highlighted. The role of energy companies as the key economic entities in providing the resilient development of regional socio-economic systems is substantiated. A number of Russian energy companies are correlated to the regions within the federal districts. Based on the review of the sustainable development concept, the gaps in the theory of regional economic resilience and in the methodology of qualitative evaluation ofthe energy sector’s participation are stated. A comprehensive approach combining the debt limitation methodology with the conceptual model by C. Walsh is suggested for the estimation of sustainable development in the energy sector. The application of the approach using the example of Russian energy companies revealed the key factors of imbalance in operating and investment efficiency management.
