Abstract

This paper investigates the influence of industrial activity volatility and exchange rate volatility on import container volume of the Korea during the 1999:1- 2010:9. Conditional variance from the GARCH(1, 1) model is applied as the volatility. The Johansen multivariate cointegration method and the error correction (general-to-specific) method are applied to study the relationship between import volume and its determinants. The empirical results show that volatility has statistically significant negative effect on import volume.

본고는 환율변동성과 경기변동성이 우리나라 수입물동량에 미치는 영향의 방향, 크기, 지속기간을 분석하였다. 본고에서 도입하는 모형이 안정적임으로써 허구적 회귀 가능성을 배제하는 것으로 나타남에 따라 장기균형식과 오차수정모형을 이용하여 수입물동량이 변수들에 의해 어떠한 영향을 받는가에 대해 추정하였다. 예상한 대로 장기방정식의 추정결과에서 경기의 호조는 수입물동량의 증가를, 변동성의 증가는 수입물동량을 감소시키는 것으로 나타났다. 수입물동량에 미치는 영향은 환율변동성이 경기변동성보다 더 큰 것으로 나타났다. 또한 오차수정항의 계수가 음의 부호로 매우 큰 값을 나타내 빠른 속도로 장기균형으로 수렴하고 있음을 알 수 있었다. 그리고 충격반응 분석결과에 따르면 반응과 지속기간의 크기에서 경기 변수가 가장 큰 것으로 나타났다.
