A Study on the Relationship between Macroeconomics and South Korea's Air Cargo Exports and Imports using Gravity Models

This study analyzed the importance of Korean air cargo transport in the increasingly close international trade and logistics network due to the acceleration of globalization and digitalization. Korea serves as an East Asian logistics hub centered on Incheon International Airport, and contributes significantly to economic growth and international trade through air cargo transport. The study analyzed air cargo exports and imports between Korea and major trading partners (the United States, China, Vietnam, and Japan) from 2003 to 2023 using a gravity model.
