摘要


發光二極體(Light Emitting Diode,LED)照明技術是一項革命性的科技,LED具有無汞、節能及使用壽命長的優點。近年來,綠能產業已陸續成為各國政府施政的主軸之一,基於LED上述的優點,加上龐大的市場商機,使得該產業正處於百家爭鳴的成長階段。台灣LED產業之產量已達到全球第一,產值達到全球第二。由此可見,台灣已在全球LED 的產業競爭中已佔有一席之地,也是最具潛力成為兆元產業的新星。在LED 的全球競爭中,台灣LED 廠商必須瞭解自身的營運績效,並且不斷提升,才能維持其競爭優勢及保有領先地位。 本研究主要是以資料包絡分析法中CCR模式、BCC模式及Malmquist生產力指數來探討各發光二極體廠商經營績效,並透過客觀的數據分析,找出發光二極體廠商中最具經營效率之廠商,而經營效率較差之廠商,則可透過數據了解是因規模或技術效率衰退影響所致,進而可以改善其經營效率。 綜觀本研究數據顯示,在CCR與BCC模式中可發現,只有佰鴻在2007年至2011年間的整體技術效率值均維持在1,表示佰鴻在這五年當中,不論是純粹技術效率或規模效率均達到相對有效率的狀態,是屬於相對有效率的廠商。由於CCR與BCC模式並無法處理跨年度資料分析與比較,故以Malmquist生產力指數來比較跨年度資料分析,從2007年到2011年各廠商的Malmquist生產力指數中發現,生產力指數改善提升最多的是東貝及光鼎(1.007),東貝是因為純技術效率變動指數(Pe-ch)成長的因素所致,光鼎則是規模效率變動(Se-ch)成長的因素所致;生產力衰退最多的廠商則是廣鎵(0.838),其Malmquist生產力指數偏低的原因是因為技術效率變動(Tech-ch)、純技術效率變動指數(Pe-ch)及規模效率變動(Se-ch)皆衰退的因素所致。

Light emitting diode (LED) lighting technology is a revolutionary technology, LED has the advantages of mercury-free, energy saving and long life. In recent years, the green industry has started to become one of the Governments’ policies of the spindle. Based on the above-mentioned advantages of LED, coupled with the huge market opportunities, the industry is being in the growth stage of contending. Production of LED industry in Taiwan has reached the world's first and output value has reached the world's second. It can be seen, Taiwan has been playing important role in the global LED industry competition, also the most potential to become a trillion dollar industry in Taiwan. In order to maintain its competitive edge and retain its leading position, Taiwan's LED manufacturers must understand its operating performance and continuously improve in the global competition of the LED. This research uses Data Envelopment Analysis (DEA) and Malmquist model to evaluate the efficiency of LED firms in Taiwan from 2007 to 2011. Base on the result of dataanalysis﹐ firms can understand its operating efficiency, and then to improve operating efficiency for those firms whose operating efficiency behind others’ accordingly. The empirical dataof using CCR and BCC models showed that BRIGHT was the only firm whose overall technical efficiency in each year between 2007 to 2011 were maintained at score 1. Meaning that Bright are relatively efficient manufacturers during the past five years. Considering CCR and BCC models can not handle cross-year data analysis, so we use the Malmquist productivity index to process the cross-year data analysis.According to empirical dataof using the Malmquist Productivity Index from 2007 to 2011, Malmquist productivity index to improve the most were the Unity (1.007) and Para (1.007). The MPI getting declined the most was Huga (0.838).
