Economic competitiveness is a key factor in the sustainable development of countries in today's globalized world. Through a systematic analysis of economic competitiveness, it is possible to identify key factors that influence the success of countries within the EU. This can include labor productivity, innovation, quality of infrastructure, business environment, labor market and access to financial resources and trade routes. Understanding these factors allows countries to focus their efforts and resources on areas that are key to improving their competitiveness. Comparing best practices among EU member states provides valuable lessons and guidelines for strengthening economic competitiveness throughout the region. For example, countries that are success in stimulating innovation and investing in research and development tend to be more competitive. On the other hand, countries facing obstacles such as inflexible labor markets or outdated infrastructure often lag behind their competitors. In addition, economic competitiveness analysis allows EU member states to adapt their policies and strategies to respond to faster changes in the global economy. Through continuous analysis, monitoring and adjustment of policies and strategies, EU countries can strengthen their competitiveness and achieve sustainable economic growth. This not only ensures prosperity within the EU, but also creates a basis for strengthening the EU's position at the global level. The main problem of research on economic competitiveness on the example of European Union countries lies in the complexity of factors that influence competitiveness, as well as in the need to find the most effective strategies for improving competitiveness within the diverse economic context of the EU.
