After Granger test, we found the most important significant variables are GRDP, CPI, PPI and interest rate, followed by analyzing the VAR model. Through the impulse response function & variance decomposition analysis. It reveals that increasing expenditures in Pusan port causes decreasing interest rate, especially short-run interest rate.
