Європейський Союз як ключовий партнер України у формуванні нової моделі економічної безпеки

The purpose of the work is to investigate the role of the European Union as a key partner of Ukraine in forming a new model of economic security, to analyze key aspects of cooperation, such as macro-financial assistance, harmonization of legislation and post-war recovery, and to identify prospects and challenges of Ukraine’s integration into the European economic space. The research methodology is based on a comprehensive analysis of scientific and theoretical sources, regulatory legal acts of the EU and Ukraine, as well as empirical data on economic cooperation between Ukraine and the EU. The system-structural method was used to analyze cooperation mechanisms, the comparative law method to assess the harmonization of legislation, and the logical-semantic method to clarify the key concepts of the study. The study found that the European Union is a strategic partner of Ukraine, providing significant macro-financial support, contributing to the harmonization of national legislation with the acquis communautaire and playing a leading role in creating conditions for the post-war recovery of the Ukrainian economy. It is proven that the implementation of European standards in the field of economic policy creates a basis for strengthening the economic security of Ukraine. However, the study also revealed significant challenges related to the need to modernize the institutional system, adapt to European norms and overcome dependence on external financial assistance. The work offers a new approach to understanding the role of the EU in shaping the economic security of Ukraine, focusing on the complex impact of macro-financial assistance, harmonization of legislation and sanctions policy on the development of the Ukrainian economy. For the first time, the impact of post-war EU initiatives on the economic stability of Ukraine has been systematically studied. The results of the study can be used to improve the strategy of economic security of Ukraine in the context of integration into the EU. Practical recommendations can serve as a basis for developing state policies in the areas of economic development, legal regulation and investment attraction.
