摘要

近年來，全球科技產業國際化及分工化態勢明顯，各國在市場競爭特別激烈，2018年以來，中國已成為全球各TFT-LCD面板零組件業者主要擴展地區，而日本、韓國因大尺吋面板市場競爭激烈，已將重心轉至發展AMOLED，各業者積極進行差異化與新技術的拓展，企圖發展新經營策略。
本研究應用二階資料包絡分析法評估台灣面板業者2008年至2019年經營績效，根據面板營運過程分成獲利階段與市場階段進行探討；並採用麥氏生產力指數，評估業者在跨期經營績效的變化。
研究結果，在整體技術效率第一階段獲利能力平均為60.1%，第二階段市場能力71.4%。純技術效率部分，在獲利能力平均為67.8%，優於市場能力規模效率58.1%。規模效率部分，在獲利能力規模效率平均為90.3%，優於市場能力規模效率76.5%。
故本研究發現面板業者市場中，具有獲利能力業者不一定在市場能力表現也佳，而且兩階段皆是整體規模效率高於純技術效率值，無效率業者表示獲利能力偏低，應適時調整規模效率。

In recent years, the trend of industrial internationalization uder global division of labor has become obvious. There exists tough competition among the coutries as well as their offers. Since 2018, China has become the main expansion area of TFT-LCD (Thin-Film Transistor liquid-Crystal Display, TFT-LCD), panel components industry in the world. Japan and South Korea, due to the tough competition in large-scale panel market, have shifted their focus to tth development of AMOLED (Active-Matrix Organic Light-Emitting Diode, AMOLED). All industries are expanding the difference and new technologies in order to develop new business strategies.
In this thesis, that uses the second-order data envelopment analysis (DEA) to evaluate the operating performance of Taiwan's panel industry from 2008 to 2019. According to the panel operation process, it can be divided into the profit-making stage and market stage.
In addition, this thesis adopts the Macintosh productivity index (MPI) to evaluate the change of business performance. The results in this thesis show that the average profitability of overall technical efficiency in the first stage is 60.1%. The market ability in the second stage is 71.4%.
In terms of pure technical efficiency, the average profitability is 67.8%, that is better than the market capacity and scale efficiency. In terms of scale efficiency, the average profitability scale efficiency is 90.3%, which is better than the market ability scale efficiency.
Therefore, in the panel industry market, profitable companies may not perform well in the market. The companies should be adjusted scale efficiency for their internationalization and business performance.
