本研究以三階段資料包絡分析探討在95到97學年度三年間國內近年升格的私立技職院校的經營績效。研究藉由三階段的調整，期望觀察出各技職院校在摒除環境和產出品質的影響下，真實的學校經營效率表現。結果顯示，當學校屬性為中部學校、南部學校、中型規模學校、科技大學等與各項投入差額之間，具有正向關係，而學校屬性為商科重點或其他科的學校、大型學校等與各項投入差額之間，具有負向關係。而在排除外在因素與統計干擾的影響後，本研究發現各高等技職院校的技術效率、純技術效率與規模效率的差異會減少，多數高等技職院校管理效率仍有改善空間，且亦有部分無效率來自於規模無效率，除部分技職院校處於固定規模報酬階段外，其餘多數技職院校皆處於規模報酬遞增階段。 / This paper uses the three-stage data envelopment analysis (DEA) to measure performance efficiency of the private vocational and technological colleges which are elevated recently in Taiwan during the 2006-2008 periods. With the three-stage adjustment, the researcher presented the relationship between the outside environmental factors among the considered colleges and the input slacks. After excluding the impacts from outside environmental factors and statistical noises, the study finds that the differences among the technical efficiency, the pure technical efficiency, and scale efficiency of the considered colleges would be decreased. In addition, it is also found that most considered colleges have opportunity to improve their efficiency and are in the phase of increasing returns to scale.
