| Summary: | 碩士 === 國立交通大學 === 工業工程與管理系所 === 95 === We use data envelopment analysis (DEA) with five indicators to measure the productivity change of 15 semiconductor packaging and testing firms in Taiwan between years 2000 to 2003. Instead of radial-based model, we use slacks-based measurement (SBM) to have more accurate measurement. Furthermore, super-SBM model is employed to measure the super efficiency. We employ Malmquist productivity measurement to analyze four events for each firm- the technical change, the frontier forward/backward shift, the productivity shift, and comprehensive productivity. Our approach excavates the deeper management implication and provides some new interpretations. Therefore, competitiveness of each firm against others would be realized.
