This study evaluates the impact of Korea’s major Free Trade Agreements (FTAs), particularly the Korea–China Free Trade Agreement (KCFTA) and the Korea–United States Free Trade Agreement (KORUS), on Korea’s export performance using econometric and machine learning approaches. Quarterly trade and macroeconomic data were collected from KOSIS, the IMF, the World Bank, and the National Bureau of Statistics of China (NBS). A Difference-in-Differences (DiD) framework was used to estimate relative treatment effects before and after FTA implementation, while Stepwise Regression, Ridge, Lasso, Elastic Net, and Random Forest models were applied for robustness and predictive analysis. The findings do not provide strong evidence that the FTAs generated additional positive export effects during the study period. Instead, GDP and exchange rates emerged as more significant determinants across most models. Among the predictive models, Random Forest demonstrated the strongest predictive performance with the lowest prediction errors. The study highlights the value of combining causal econometric analysis with machine learning techniques to evaluate trade agreement effectiveness from multiple analytical perspectives.
