내항화물운송업 경영실적 통계조사의 개선방안 연구

Abstract

In Korea, coastal cargo transport plays the role of an essential transport network, shipping crude oils and oil products, iron ore, cement, iron steel and articles thereof and other ores. Since early 1990s Korean government has deregulated restrictions through abolition of shipping tariff filing system, liberalization of import for secondhand ships and adopting registry system for coastal cargo shipping business. In 2003 the government permitted ocean-going cargo transport companies to participate in coastal cargo shipping. Though coastal cargo shipping companies have appealed to the government for financial difficulty issued by severe competition, they do not have official and impartial statistics for the financial statement. The Korea Shipping Association as the organization of coastal cargo shipping companies has made and utilized the financial statement statistics since late 1990s, but the data could be evaluated to fail to reflect exact market conditions because the sample does not represent sufficiently the population. This study suggests the improvement for the representative of the sample through adopting stratified sampling and through designing sample size and allocation to reflect the characteristics of the population.
