The article is devoted to the research of economic policy for stimulating regional competitiveness in conditions of macroeconomic instability, spatial polarization and the consequences of the full-scale war in Ukraine. The relevance of the topic is determined by the need to modernize regional development mechanisms in the context of global challenges, in particular the demographic crisis, institutional asymmetry, the digital divide, and structural depletion of peripheral regions. The research is based on the hypothesis that an effective policy to stimulate regional competitiveness is possible provided that the European development vector is integrated with the values of security, sustainable development, institutional capacity, digital transformation of public administration, and differentiated consideration of spatial asymmetries between regions. The research methodology is based on general scientific and specialized methods, including systemic, institutional, comparative, factorial, structural-logical, statistical, spatial, cluster, and graph analytical approaches. The research contains the results of a comparative analysis of the regionsʼ competitiveness of Poland, Lithuania, and Ukraine in the Lublin Triangle architecture, it analyses geospatial differentiation, and identifies transformation vectors of regional development in the context of the war in Ukraine, in particular digital adaptation, demographic response, institutional mobilezation, and mechanisms for stimulating innovation. A conceptual model for aligning sustainable development values with economic policy for managing competitiveness at the regional level is proposed. The results of the research made it possible to develop new conceptual approaches to assessing the effectiveness of economic policy for stimulating regional competitiveness and to justify directions for its further improvement
