the Covid-19 pandemic on South Korea’s regional export structure, with an emphasis on understanding how global events like pandemics can reshape regional export structures. Thus, it seeks to identify changes in regional competitiveness and the shifting patterns in industrial exports that occurred due to the pandemic. Design/Methodology – The research uses export data by applying Export Similarity Index and Revealed Comparative Advantage to gauge changes in the export structures of various regions in South Korea. By comparing data from before and after the onset of the Covid-19 pandemic, the study provides a comprehensive look at how regional export markets have adapted and changed in response to global economic disruptions. Findings – The study uncovered a notable shift in the export structures across regions of South Korea because of the pandemic. During the pandemic, there was an increase in the similarity of exports across regions, indicating a convergence of regional export strategies. Post-pandemic, a diversification trend emerged, reflecting a response to changing global market demands. Notably, certain regions displayed a remarkable resilience, maintaining their competitive advantage in specific industries despite the global economic turmoil. Originality/value – This study contributes a new dimension to the understanding of export competitiveness, particularly in the context of South Korea. By providing a regional perspective, it offers insights into how global events like pandemics can lead to significant shifts in regional economic structures. The findings are particularly valuable for policymakers and business leaders, offering guidance in the development of strategies to enhance regional export competitiveness and ensure balanced economic development in the face of future global challenges.
