Abstract: Export-based growth strategies have led to increasing economic competition between countries. A country's global competitiveness is shaped by the influence of various factors, and determining these factors is of great importance. This study, which examines the determinants of competitiveness, is based on Porter's (1990) Diamond Model. In addition, three different models were developed in line with Dunning's (1992) contributions to Porter's Diamond Model and an alternative perspective. In this research, which covers Türkiye and 11 European Union member countries, annual data between 1995-2019 were used. In the study, the competitiveness index developed by Balassa was calculated for two different groups of goods that require high technology and are included in the Harmonized System. To explore the relationships among the variables, the Seemingly Unrelated Regression (SUR) method was applied. The empirical findings revealed that determinants such as market demand, resource conditions, industry support structures, competitive strategies, regulatory policies, and productivity levels have statistically significant both positive and negative effects on international competitiveness. In addition, it has been determined that the effects of these variables differ both across the examined commodity groups and countries.
