根據內政部營建署的統計,截至2014年第二季為止,我國營造業的規模,已達到16,987家,資本額總計新台幣6,571億,而營造業與金融保險不動產業,佔我國生產毛額GDP的比率,分別為2.98%與15.78%。顯示該產業在我國整體經濟中,一直扮演重要的角色。但近年來,我國經濟的發展遲緩、物價上漲及政府政策的改變,對不動產業與營造業造成相當的衝擊。因此,如何在這兩項產業中,找出指標性企業,使得產業內各企業能有良好的學習典範,是值得研究探討的議題。本研究以二階段資料包絡分析(data envelopment analysis, DEA)模式,分析我國上市、櫃70家不動產業與營造業廠商的經營效率與獲利能力,針對經營效率較差或獲利能力較差的公司,提出改善建議,並將上市、櫃公司的各項效率值做比較分析,並以保證範圍模式(assurance region, AR)及折衷權重模式(common compromise weights, CCW)做進一步排序比較,最後再分析比較各上市、櫃公司的經營效率與獲利能力之間的關係。結果可供各營造業與不動產業的經營者,作為爾後經營、改善之參考。
According to the statistics of the Construction and Planning Agency, Ministry of the Interior, up to the second quarter of 2014, the scale of construction industry in our country has reached 16,987 companies; total capital reached NT$ 657.1 billion. The percentage of construction industry and real estate industry to the gross domestic product (GDP) were 2.98% and 15.78%, respectively. It reveals that these industries have been playing an important role to the overall economy. However, the slow economic development in recent years, inflation, and the changes of government policies has caused considerable impact on the real estate industry and the construction industry. Therefore, how to identify the indicators of enterprises in these two industries so that other enterprises have a good learning model is an interesting research topics worth to investigate. Using two-stage data envelopment analysis (DEA), this study tries to analyze the operational efficiencies and profitability of seventy companies in real estate industry and the construction industry, and provide recommendations of improvement for those inefficient companies. Then, compare the operational efficiency and profitability of listed company and over-the-counter (OTC) company. At last, distinguish and sort those efficient companies by assurance region (AR) model and common compromise weights (CCW) model. Results can be used as recommendations for the managers in construction industry and real estate industry.
