Selected Digital Services in Building a Resilient and Sustainable Economy Ukraine's Experience Implications for European Union Countries

The article analyzes the role of selected digital services in maintaining the functioning of the Ukrainian state and economy in wartime conditions and assesses their adaptive po-tential for European Union countries in the context of sustainable and resilient develop-ment. The starting point was the concept of institutional and economic resilience, which has grown in importance in the context of global crises, contributing directly to the goals of sustainable development and long-term socio-economic stability. A qualitative and quantitative approach was used, including secondary data analysis, comparative analy-sis, and triangulation of sources. The results of the study showed that platforms such as Diia, Diia.Business, eRobota, and Air Alert played a key role in ensuring the continuity of public services, support for businesses, and crisis communication. The integration of these tools into the public management system enabled Ukraine to maintain basic state func-tions despite the ongoing armed conflict. A comparative analysis with Estonia, Poland, and Denmark confirmed that the Ukrainian model can be a source of inspiration for EU digitalization strategies, particularly in the areas of mobile administrative services and integration with crisis management systems. The article's conclusions emphasize the importance of digitization as a strategic resource that strengthens the resilience and sus-tainability of public institutions and economies in emergency situations.
