碩士 === 國立高雄第一科技大學 === 企業管理研究所 === 94 === Abstract This research is based on the data of 14 listed companies of the TFT LCD Industry and the Key Component Industry in Taiwan during the 2000~2004 periods. Data Envelopment Analysis (DEA) is employed to evaluate the performance of the companies by using the number of employees, fixed assets, and operating costs as the input variables; net sales revenue as the output variable. We choose three industries and calculate the values of technical efficiency, pure technical efficiency, scale efficiency, slack variables, and Malmquist index. The empirical results are as follows: 1. The technical efficiency of panel industry in 2001 was 0.642, the lowest over these years, while 0.925 in 2004 was the best. The back light industry in 2000 was the lowest over these years for 0.828, mainly came from the scale inefficiency, and the technical efficiency raised up year by year since then. After reaching considerable scale economy and technology development in 2004, the technical efficiency is up to 0.905. The technical efficiency of the TFT LCD drive IC industry was 0.925 in 2000, 0.874 in 2001, 0.901 in 2002, 0.931 in 2003,and 0.912 in 2004, respectively. 2. Analyzing the slack variables, we can provide the strategy for enterprises to enhance productive efficiency by adjusting their input and output variables. For DEA research result in 2004：AU Optronics Corp.is comparatively efficient as the benchmark for other panel companies in technical efficiency. K-Bridge electronics Corp. and Radiant Optoelectronics Corp. are comparatively efficient as the benchmark for other back light companies in technical efficiency. Novatek icroelectronics Corp. is comparatively efficient as the benchmark for other TFT LCD driver IC companies in technical efficiency. iii 3. For the result of Malmquist productivity index, technical efficiency changes influence the productivity of TFT LCD Panel and drive IC companies quite obviously. Every company of the back light industry is influenced relatively a few by pure technical efficiency changes.
