營建產業為國家經濟建設重要的一環,與國計民生關係密切,同時又牽連著相關產業之發展,許多研究已經透過使用各種方法進行分析台灣的建築公司表現,並獲得有用和有價值的結果。一般認知營建業為高獲利的行業,然而隨著景氣循環以及物價高漲時代,營建業經營不如過去容易,本研究試圖以資料包絡分析法來評估國內上市櫃營建公司2007年到2012年之經營績效,儘管使用資料包絡分析法可以評估績效,但有可能同時產生有效率的決策單元,使用超級效率分析,我們可以改善相對無效率的公司並進一步增加其鑑別度,此外差額變數分析可以顯示如何改善投入項以及產出項以使相對無效率的公司改善成為相對有效率的公司,期望藉由實證結果分析個別廠商過去之經營效率情形,作為營建公司未來經營方向及提升經營效率之參考依據。
Construction industry is important for national economy and people's livelihood is closely related. Many studies have been conducted to analyze the performance of construction companies in Taiwan by using various methods and obtain useful and worthwhile results. This study attempts to utilize data envelopment analysis (DEA) to assess the operating performance of the domestic listed construction companies from 2007 to 2012. Although using DEA to evaluate performance is quite promising, more than one efficient decision making unit (DMU) may occur. Using the super efficiency analysis, we can improve the discrimination of the results obtained by DEA and rank efficient DMUs further. Moreover, slack variable analysis is included to analyze the inefficient DMUs and find the way of improving the inputs and outputs of the inefficient DMUs such that the inefficient DMUs could be efficient. The results obtained also provide managers insights to make executable strategies or to form future business directions to enhance operational efficiency.
