공컨테이너(Empty Container)는 적컨테이너(Full Container)와 달리, 화물이 적재되지 않은 비어있는 컨테이너로 공컨테이너 재고는 수출에 비해 수입이 많은 항만에서, 수요는 수입에 비해 수출이 많은 항만에서 발생한다. 그러나 수입과 수출은 기간, 지역에 따라 유동적이기 때문에 수요와 재고량 예측에 어려움이 있는데, 본 연구에서는 자기회귀누적이동평균(ARIMA)과 머신러닝 기법을 활용하여 이를 예측하는 방법을 제시한다. 본 연구에 활용된 데이터와 프로그램 소스코드는 Kaggle 에 공개되어 있다.

식품 등(식품$\cdot$첨가물$\cdot$기구$\cdot$용기 및 포장)을 수입코자 할 때에는 영업소를 관할하는 시군$\cdot$구청 위생과에 식품판매업신고를 필하고 수입할 때마다 수입항을 관할하는 검역소에 수입신고를 하여 검사를 받아야 한다. 판매를 목적으로 수입하는 식품등은 보건사회부장관이 정하여 고시하거나 인정한 규격 및 기준에 적합해야 하며, 수입한 식품 등에도 식품위생법에서 정한 표시기준에 의한 표시를 한글로 해야 한다. 이상의 제반요건을 갖추지 못한 식품등은 판매나 영업을 목적으로 수입할 수 없다.

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.

This study examined the impact of geopolitical risk on port throughput in Korea. With a high trade-to-GDP ratio, Korea has an open economy. The vast majority of its exports and imports are serviced by maritime transport. Therefore, cargo volume of Korean seaports is highly likely to be affected by changes in global economy resulting from escalation in geopolitical risk. In this regard, this study investigated the relationship between geopolitical risk and port throughput in Korea during the period of 1995-2022. Results indicated that the impact of geopolitical risk on port throughput was not statistically significant. However, the relationship varied by export, import, and ports. Especially, it was revealed that cargo volume of Korean ports was negatively associated with the level of geopolitical risk. In addition, it was also found that geopolitical risk had a negative impact on the unit price of Korean import..

This study investigates the difference of behavioral patterns between the import container volume of all ports and that of Gwangyang port in Korea. All series span the period January 1999 to December 2008. I first test whether the series are stationary or not. I can reject the null hypothesis of a unit root in each of the level variables and of a unit root for the residuals from the cointegration at the 5 percent significance level. I hitherto make use of variance decompositions and impulse response functions, both of which have now been widely used to examine how much movement in one variable can be explained by innovations in different variables and how rapidly these fluctuations in one variable can be transmitted to another. The variance decompositions for the import container volume show that the proportions of the forecast error variance of import container volumes explained by themselves are 30 and 26 per cent after 12 months, respectively. As a result, innovations in exchange rate and business activity explain 70 and 74 per cent of the variance in the import container volume. All in all, innovation accounting indicates that import container volumes are not exogenous with respect to exchange rate and business activity. The impulse responses indicate that container volumes decrease sharply to the shocks in exchange rate and decay very slowly to its pre-shock level, while container volumes respond positively to the shocks in the business activity and disappear very slowly, showing that the shocks last very long. Furthermore Gwangyang port is more sensitive to the change of the exchange rate and the industrial production than all ports.

Free Trade Agreement(FTA) aims at abolishing tariffs on trade among nations or regions resulting in having a significant impact on maritime transportation and port. Korea made the first FTA with Chile in 2004 and the trade volume between two countries has seen significant increase. The literature on such impact, however, seems to be very limited. The main purpose of this study is, therefore, to analyze the impact of Korea-Chile Free Trade Agreement on the imported container throughput from Chile at the Busan Port. For this both cross-sectional and time series data are collected that comprise container throughput, Gross Domestic Product (GDP), import tariff, and maritime freight rate, from 2000 to 2011, and the gravity model is applied. The main result of the study shows that the dependent variables, GDP and import tariff are statistically significant, but the maritime freight rate is not consistent with regarding to statistical significance and parameter sign.

침체된 세계경제가 회복할 기미는 보이지 않고, 재정수입을 확보하지 못한 정부들은 민간자본을 이용한 인프라 건설사업 추진을 선호하고 있다. 이런 자본을 동반한 해외사업의 추진을 위해서는 정부, 금융권, 건설사가 협업하는 사업모델이 절실하다. 본 연구는 해외항만 개발사업분야 중에서 인도 항만시장을 중심으로 기회와 장애요인, 현황분석을 통해 해외 건설사업 지원의 핵심 경쟁력에 대해 제언하였다.

인천항은 한국의 주항의 하나로 원자재 수입화물을 취급하는 항만이다. 수입된 원자재 중에서 대두박등의 사료 부원료의 취급 시 강한 바람, 차량의 이동, 저장시설에서의 상하차 등에 의하여 다량의 비산먼지가 발생하여 인천항의 주된 비산먼지 오염원이 되고 있는 실정이다 (Jeon et al., 2000). 일반적으로 사료 부원료의 취급에 의하여 발생하는 비산먼지의 제진을 위하여, 사료 부원료 취급시설에 bag filter에 의한 제진시설이 사용되고 있다. (중략)
