Abstract:	本研究以向具經濟火車頭之稱的營建業為研究對象，採用能比較不同生產技術群體的共同邊界投入導向距離函數，探討經營模式有所差異的營造與建設兩次產業公司的共同邊界技術效率。搜集台灣2000年至2007年24家營造業及59家建設業公司不平衡的縱橫資料，共計561個樣本點，進行迴歸分析後，主要發現如下：首先，在技術效率、技術缺口比率及共同邊界技術效率等指標，建設業公司均顯著優於營造業公司。其次，營造業公司之規模報酬平均值僅微幅高於建設業公司，兩個次產業之公司若經由購併等方式擴大生產規模，均可降低其長期平均成本且強化公司之競爭力。This paper is to compare technical efficiency of metafrontier with the sample firms of construction and real estate industries having different business model and belonging to sub-industries of construction known as the economic engine. This study adopts a model integrated metafrontier input distance function due to its ability to associate multi-inputs with multi-outputs under different production techniques groups. The research period from 2000 to 2007, 24 firms from construction industry and 59 firms from real estate industry are collected, total 561 unbalanced panel data. The main results are as follows. First, this study found that technical efficiency, technology gap ratio and technical efficiency of the metafrontier on the firms of real estate industry are significantly better than those on the firms of construction industry. Second, this study found that average value of returns to scale for construction industry`s firms only slightly higher than those for real estate industry`s firms. Moreover, the companies on two sub-industries could reduce long-term average costs and strengthen their competitiveness if the companies on two sub-industries expand production scale through mergers and acquisitions.
