The priorities for Ukraine’s post-war reconstruction in preparation for its membership in the European Union are to ensure integration, efficient use of resources, socio-economic growth, and sustainable development. Finding ways to effectively develop the economic and other sectors, adapt to European norms and create a sustainable framework for integration into the European space was the purpose of this study. The methodology is based on the empirical research method. The reform priority coefficient was calculated using a formula for determining the priority areas for improving the economic, demographic, and political sectors of Ukraine. The study identified priority areas for Ukraine’s post-war development, including mechanisms such as ensuring sustainable economic growth, modernising infrastructure, developing trade relations with EU countries, supporting innovation and entrepreneurship, improving the quality of education and healthcare, which can be used by scientists and the state to ensure the country’s effective development and obtaining the status of a full EU member. The importance of ensuring social protection of the population, including raising living standards and ensuring access to basic social services, was identified. The study found that effective economic diplomacy and the expansion of international relations with EU member states are crucial factors for Ukraine’s successful preparation for EU membership. The focus is on ensuring strategic orientation, efficient use of resources and achieving the country’s socio-economic development in line with European standards and values. In practice, these results can become the basis for developing strategic decisions and programmes in line with EU criteria
