Abstract

The purpose of this research is to analyze the efficiency of the Chinese repair shipbuilding industry using a DEA model with 12 Chinese repair shipbuilding companies. Unlike preceding studies, this study has different research subjects as well as selected input and output variables. The research was conducted with competitive Chinese companies in the market. For the efficiency analysis, input variables included the number of technicians as well as facilities, and output variables were diversified with relevant factors using the number of repaired ships and service ranges as well as sales. The differences were analyzed by including only facilities as an input variable for the DEA model, and then both facilities and technicians. For inefficient DMUs, the strengths and weaknesses were analyzed by finding the causes through a reference group, which was developed into an efficient DMU. Moreover, public and private companies were separated to develop improvement measures.

본 연구는 12개 중국 수리조선 업체를 대상으로 DEA모형을 활용해 중국 수리조선산업의 효율성을 분석하고자 하였다. 기존 연구들과 달리 본 연구에서는 연구대상 뿐만 아니라 선정된 투입과 산출변수도 차별성을 지닌다. 연구대상은 수리조선시장에서 경쟁우위를 보이고 있는 중국의 업체를 대상으로 진행하였다. 효율성 분석을 위한 투입변수는 시설 외에 기술자 수를 고려하였으며, 산출변수는 매출액 외에도 수리선 척수 및 서비스 범위를 사용하여 관련 변수들을 다양화하였다. 분석에는 DEA모형에 의하여 시설만 투입변수로 한 경우 및 시설과 기술자 수를 투입변수로 하여 차이점을 분석하였다. 비효율적인 DMU의 경우, 효율적인 DMU가 될 수 있도록 참조집합을 통해 비효율성의 원인을 찾아 장단점을 분석하였다. 또한 국영기업과 민영기업을 구분해서 개선방안을 도출하였다.
