The more the satisfied customers increases in customer satisfaction survey, the more the company has difficultly in improving the customer satisfaction. In addition, the effectiveness of practical application of customer satisfaction survey decreases due to its constitution limitation on its data analysis. To overcome these problems, it is necessary to develop a new method to identify the strategy meanings and find the dissatisfied factors of satisfied customers using the satisfied customers reclassification. This study focuses on the satisfied customer segmentation using Latent Class Analysis. The case study shows that the satisfied customers are divided into three subgroups using Latent Class Analysis and we draw meaning results such as satisfaction and dissatisfaction factors through analyzing each group. This study is expected to play the role as the groundwork for the revitalization of customer satisfaction survey.

본 연구에서는 항만의 주요고객인 선사를 대상으로, 국외선사와 국내선사로 세분화하여 속성의 중요도와 항만 선호도 차이를 비교분석하였다. 컨조인트 분석 결과 국내선사와 국외선사 간의 항만선호도에서 분명한 차이를 보였으며, 이러한 차이는 기항지와 환적항에서 동시에 나타났다. 국외선사들은 환적항으로서 상하이항을 가장 높게 평가했지만, 국내선사들은 부산항을 상하이항보다 높게 평가했다. 또한, 기항지 선호도 비교에서도 비슷한 결과를 나타냈다. 이러한 연구결과는 국내외 선사에 따라 항만 선호도가 다르기 때문에 집단별로 구분하여 평가할 필요가 있음을 의미한다. 또한, 이를 바탕으로 타항만에 비해 경쟁위위에 있는 부산항의 선호도를 유지하기 위해서는 지속적인 목표(Target) 마케팅이 필요하며, 주요 목표(Target)는 항만의 주요 고객인 선사임을 암시한다.
