Abstract

This study analyzes the effects of freight transportation income, capital, asset, non-operating expenses, and debt ratio on the debts of inner port freight transportation businesses through the GLS of panel regression analysis and the estimation of fixed effects model. The factors and hypotheses were established through a theoretical background review, and the financial statement and profit and loss data of inner port freight transportation businesses for 10 years from 2006 to 2015 were analyzed. The results showed that assets had positive effects on debts, and negative effects on capital, non-operating expenses, and debt ratio, but no effect on freight transportation income. This result empirically demonstrates the tendency of inner port freight transportation businesses to secure assets by increasing debts, creation of debt reduction leverage effect using non-operating expenses such as interest expenses through bank borrowing, and the adoption of management characteristics and financial operation method to lower the debt ratio by reducing capital more than debts. In future studies, it is necessary to analyze coastal port freight transportation business by industry (oil tankers, cargo ships, and barge ships), and regions such as East, West and South sea.

본 연구는 패널회귀분석의 GLS 및 고정효과모형 추정을 통해 내항 화물운송사업의 화물운송수입과 자본, 자산, 영업외 비용, 부채비율이 부채에 어떠한 영향을 미치는지 분석하였다. 이론적 배경을 통한 요인과 가설 설정, 2006년부터 2015년까지 10년간 내항 화물운송사업체의 재무상태표, 손익계산서 자료를 분석한 결과, 자산은 부채에 정(+)의 영향, 자본과 영업외비용, 부채비율은 부채에 부(-)의 영향을 끼치며, 화물운송수입은 영향을 미치지 않는 것으로 나타났다. 이러한 결과는 내항 화물운송사업체가 부채확대로 자산 확보하려는 경향, 은행차입을 통한 이자비용 등 영업외비용을 활용한 부채감소 레버리지 효과 창출, 부채보다 자본을 줄여 부채비율을 하향조정하고 있는 경영특성과 재무적 운영방식을 채택하고 있음을 실증적으로 보여준다. 향후 연구에서는 내항 화물운송업체를 업종별(화물선, 유조선, 예부선), 지역별(서해권, 남해권, 동해권)로 세분화하여 분석할 필요가 있다.
