發光二極體(light emitting diode, LED)是劃時代的照明科技,根據美國市場調查機構(Strategies Unlimited)估計,2007年全球LED之市場規模約為46億美元,截至2012年全球LED市場帄均年複合成長率高達20%,目前台灣LED之總產值佔全球22%,位居第二。本研究欲透過灰關聯分析,找出台灣LED廠商之灰關聯係數,同時使用Entropy計算其經營績效評估準則之權重。經由客觀的數據分析,提供管理結論作為業界在維持經營績效及提高競爭優勢時之參考。本研究標的為14家台灣LED專業廠商,研究期間為2002年~2007年,以期完整反應出LED廠商之總經營趨勢表現,達到本文之研究目的。研究結論發現在2002年~2007年期間內,LED上中游廠商中,以晶電之經營績效表現呈逐步上升趨勢。就下游廠商而言,則以億光表現較佳。經針對數據與個案作深入分析,本研究建議LED廠商在專利障礙部份應積極善用台灣廠商的競爭優勢與國際LED大廠進行策略聯盟,以取得專利授權。此外也頇提升本身的技術層次、積極創新與研發、掌握市場趨勢、改善產品組合、產能調配效率、降低生產成本,以便提升其競爭優勢,擴大全球佔有率與利益。
Light Emitting Diode (LED) is an innovative lighting technology. According to the estimation of the research company, Strategies Unlimited, the global market size of LED industry is 4.6 billion US dollars in year 2007 and the cumulated average growth rate till year 2012 is estimated to be 20%. Taiwan LED companies owned the worldwide second large market share, 22%, which have an important position worldwide. The background above led to this paper, analyzing the operation performance of Taiwan LED companies and providing suggestions for future improvement respectively. This research encompasses all public financial data from the 14 pure LED companies in Taiwan, covers from 2002 to 2007. This research applies the technique of Grey Relational Analysis (GRA) and Entropy to assess the performance of Taiwan LED industry and provide suggestions to improve Taiwan LED companies' performance. From our research results, the performance of EPISTER and EVERLIGHT are relatively high among other LED companies. After a further analysis of these two companies, this research suggests Taiwan LED companies should build up strategy alliances with worldwide LED leaders for cross licensing. Moreover, they should enhance their technology capability, accelerate in R&D and innovation, grasp the market trend, improve product mix and manufacturing efficiency and reduce the cost. In consequence, they can improve their competitive advantages and enlarge worldwide market share and benefit.
