| Summary: | 碩士 === 國立成功大學 === 高階管理碩士在職專班 === 97 === After rapid development in TFT-LCD industry from 2000 to 2007, the production capability of TFT-LCD firms has expanded tremendously in Taiwan, Japan and South Korea. However, due to the global economic decline, the demand has reduced hurriedly in the third and fourth quarters of 2008. The fast change from boom-and-bust, of demand has coused Taiwan's TFT-LCD factory to encounter in operating difficult. This study selected 10 major TFT-LCD companies as the sample firms , 7 of them are Taiwanese firms listing at Taiwan’s firms that listed in Taiwan stock market, including CMO, AUO, CPT , Innolux, HannStar, TPO, Wintek, others are Sharp from Japan, and Samsung and LG from South Korea.
Data envelopment analysis (DEA) is used in this study to rank the performance of firms for the sample firms. The research attempts to use Analysis of Efficiency, Slack Variable Analysis, and Malmquist Productivity Index (MPI) to measure the efficiency frontiers of TFT-LCD industry in Taiwan, Japan and South Korea In order to investigate efficiency frontiers from different perspectives, this study designs four Input-Output Models in the DEA analysis.
The input variables include staff population, financial structure, total assets, cost of operating, research and development expense, intellectual capital at the beginning period, the output variables include business income, benefit before tax , business capacity, profitability, cash flow, and intellectual capital at the end of the period .The study tries to find the benchmark firms and the input and output slacks to understand the relative position of the sample firms. The results indicate that, about half of TFT-LCD firms in Taiwan are very competitive worldwide.Those firms that are not in efficient frontiers can learn form their benchmarking companies to understand how to adjust the scale of the firm to promote competitiveness and restructuring speed, increase sales profits, and increase profitability and total effectiveness. As a summary, it is suggested that (1) firms should put further backward integration on upstream components to reduce input costs. (2) firms should focus on niche and concentrate on the development of key technology to increase profits, (3) firm should try to own self-brand and try to expand marketing channels. It is also hope that the study findings can provide some suggestion of business efficiency improvement for Taiwanese TFT-LCD firms.
