Measuring Dynamic Operation Efficiency for Universal Top 10 TFT-LCDs by Improved Data Envelopment Analysis

Abstract

Currently the major manufacturers of TFT-LCD (Thin Film Transistor-Liquid Crystal Display) in South Korea, Taiwan and Japan and contribute 80% sales in global market. In view of the rapid growth of global demand, TFT-LCD manufacturers face tremendous competition. In this context, how to configure the best resource allocation and create more profit tend to be the major issue. In this study, the TFT-LCD firms in China, Korea and Japan is analyzed. Based on the trend analysis by Industrial Technology Research Institute in Taiwan, public database and information, financial statements and annual reports of these firms, we use improved Data Envelopment Analysis (DEA) in association with Window Analysis to measure their dynamic operating performance in China, Korea and Japan.
