ABSTRACT After the national universities in Taiwan implementing the college affairs funds, the expenditure comes from not only the government supply but also universities themselves. It¡¦s for the purpose of their needs on teaching, researching, and serving. In order to enhance the elasticity that the funds use independently and the competitiveness of higher education, it is bound to put more focus on both the managing and cost efficiency. This research adopts the efficiency-measuring mode of Data Envelopment Analysis (DEA) to weigh the conditions of managing results and efficiency fluctuations¡]the fluctuation of Malmquist productivity¡^of 51 national universities in Taiwan from year 2001 to 2004. The conclusion of obtaining is as follows: From the aspect of managing efficiency, National Chiao Tung University and National Dong Hwa University perform the best among the general universities; as for the technological universities and vocational colleges, National Taiwan University of Science and Technology and National Chin-Yi Institute of Technology perform the best. The lacks of valid managements in resource usages causes the technical inefficiencies; the general universities performed like the technological and vocational colleges were rather similar and relatively inefficient from the year 2001 to 2004. The reasons of inefficiency came from the technological efficiency of bad management with reached the scale efficiency of the best scale at the same time. The Malmquist indices of National Tsing Hua University and National Taichung University were more than 1 from the year 2001 to 2004; as for the technological and vocational colleges, the Malmquist indices of National Tai-Chung Institute of Technology, National Taichung Nursing College, National Taiwan Junior College of Performing Arts, and National Tainan Institute of Nursing were more than 1 as well. There is a decline trend gradually of productivity in 2001-2004 in both the general universities and technological and vocational colleges, it was mainly that the production technology efficiency retrogresses. Finally, implementing college affair funds may be still affected by other external objective environments, the one of great impact among them: external parameters, such as size of the school, the history of the school, and the location of the school. Through the regression analysis, there are strong correlation between campus size and management efficiency for the general universities; however, not between history and location of the school. On the other hand, the technological and vocational colleges, do not have dominance to whole efficiency value. From the analysis, we can understand the over-all performing, efficiency of the universities in Taiwan. The fund governors should manage and advent different efficiencies with various methods in order to promote the managing efficiency of the whole.
