Abstract

Many Korean construction companies have fallen on hard times because the construction business continues to stagnate. Therefore it is necessary to measure the management efficiency for efficient operation and strengthening competitiveness of them in order to survive a difficult situation. This paper proposes a combined ANP and DEA model to analyze the efficiency of the listed construction firms. In order to determine the input and output variables of DEA, the ANP model is applied to evaluate the importance of input and output variables. The benchmarking companies and efficiency value for the construction firms with inefficiency are also provided to improve the their efficiency. The 57 listed construction companies consisted of 36 listed on KOSPI and 21 listed on KOSDAQ are analyzed in this study. The analysis results show that 11 companies whose values of CCR are 1, and 14 firms whose values of BCC efficiency are 1. In additions, the 19 firms have the scalability efficiency. Finally, we test the correlation between efficiency and the stock price.

많은 국내 건설 회사들은 지속되는 건설 경기 침체로 힘든 시간을 보내고 있다. 따라서 건설기업들이 어려운 상황 속에서 살아남기 위해서는 효율적인 운영과 경쟁력 강화를 위한 경영 효율성의 분석이 필요하다. 본 논문에서는 국내 상장건설기업 효율성을 분석하기 위하여 ANP와 DEA의 결합모델을 제안한다. DAE에서 가장 중요한 투입요소와 산출요소를 결정하기 위하여 ANP 모델을 적용하여 투입요소와 산출요소의 중요도를 평가한다. 그리고 비효율성을 갖는 그룹으로 분류된 기업들에 대해서는 효율성을 갖는 벤치마킹 기업들과 이들 그룹으로 이동하기 위하여 개선해야할 효율성 수치를 제공한다. 본 연구에서는 KOSPI에 상장된 36개와 KOSDAQ에 상장된 21개로 구성된 57개의 건설기업을 분석하였다. 분석결과 CCR 모형에서 효율적으로 선정된 기업은 총 11개였고, BCC 모형에서는 총 14개 기업이 효율성을 가지고 있었다. 추가적으로 규모의 효율성이 1인 기업은 19개 기업이었다.
