The article analyzes trade patterns between South Korea and major countries in the aviation industry using a gravity model. The researchers looked at exports and imports in the aviation sector over a 20-year period, focusing on factors like GDP, distance between countries, and membership in organizations like APEC and OECD. They found that South Korea's trade volume is proportional to GDP and inversely related to distance between countries. Specifically, exports correlate with GDP per capita, while imports are proportional to GDP and influenced by OECD membership. Trade volume is also linked to GDP and distance between countries. Overall, factors like GDP, distance, and organization memberships play a significant role in aviation trade patterns between South Korea and other countries.
