摘要
本研究係採用兩階段 DEA方法探討2007年至2009年金融海嘯期間，44家全球領先電信企業的獲利力與市場力的相對效率，並透過 Malmquist生產力指數分析三年的兩階段及整體跨期績效表現。更進一步提出管理決策矩陣分析，提供相對無效率之電信業者經理人標竿參考對象及建議方向以改善績效。
兩階段DEA研究結果顯示，在2007年至2009年金融海嘯期間，第一階段約有76%的電信業者獲利力相對無效率；第二階段約有89 %的電信業者市場力相對無效率。二階段DEA三年平均結果，2007年平均效率值相對高，2008年平均效率值相對低，顯示全球電信業者經營績效受金融風暴影響，平均效率值下降。地理區域分區檢定結果顯示，亞洲與歐洲在第一階段有顯著差異，第二階段則四區無顯著差異。管理決策矩陣顯示共有13家電信業者在第一區，此13家電信業者之平均獲利力及市場力均優於其他電信業者，顯示其卓越競爭力及領先地位，可作為相對無效率電信業者之標竿學習參考對象來改善其效率。
Malmquist總要素生產力指數三年效率變化結果顯示：第一階段獲利力平均總要素生產力為上升趨勢(年度平均值1.107)，第二階段市場力平均總要素生產力為下滑趨勢(年度平均值0.916)；2008年到2009年兩階段平均總要素生產力則均為下滑(年度平均值分別為0.638,0.999)，顯示全球領先電信企業的經營績效受全球金融風暴影響，平均生產力下滑；這44家全球領先電信企業三年的平均總要素生產力為上升趨勢(年度平均值1.071)，且2007年與2009年的平均總要素生產力為上升趨勢(年度平均值1.105)，整體而言是進步，顯示具成長潛力。

Abstract
This study applies the Two-Stage data envelopment analysis (Two-Stage DEA) approach to explore the profitability efficiency and marketability efficiency of 44 leading global telecom companies during the global economic crisis in the period 2007-2009. This study also utilizes the Malmquist index to analyze operational performances of the Two-Stage and overall total factor production change from 2007 to 2009. Furthermore, we propose the managerial decision-making matrix to provide benchmarks and suggestions in order for managers in inefficient telecom industry to improve their performance.
The Two-Stage DEA results indicate that approximately 76 percent of the 44 global telecom companies have relative inefficiency in the First Stage of the profitability efficiency process and 89 percent of them are inefficient in the Second Stage of the marketability efficiency process. The three-year average score of Two-Stage efficiency results relative high efficient in 2007 and relative low efficient in 2008. This indicates that telecom industry operational performance was influenced during global economic crisis. The Scheffe post results indicate significant difference in profitability efficiency in Asia and Europe area but no significant difference in marketability efficiency between four geographic areas of telecom companies in the period 2007-2009. Thirteen telecom companies are in zone 1 in the decision-making matrix represent outstanding competitive and leading position during the global economic crisis. These thirteen telecom companies can be benchmarks and may provide inefficient global telecom companies the first guideline to learn with.
Three years of Malmquist productivity Index annual results show that the efficiency of telecom industry was influenced during global economic crisis with the annual total factor productivity change grew in First-Stage (annul means 1.107) and declined in Second-Stage (annul means 0.916) and both declined in Two-Stage in the period 2008-2009 (annul means 0.638,0.999 respectively). On average, the three-year overall Malmquist productivity Index annual results on 44 leading global telecom companies indicate further growth potential with annul means grew (annul means 1.071) and grew in the period 2007 and 2009 (annul means 1.105).
