本研究利用國內三大行動通訊業者的投入產出資料,以資料包絡分析法評估其經營效率,並利用無母數U檢定探討「技術創新」與企業經營績效之關聯性。研究結果發現:(1)台灣行動通訊產業平均整體總效率為0.855,尚有14.5%的改善空間,表示整體行動通訊產業還未達到有效率的境界,國內相關行動通訊公司還有相當的努力空間;無效率來自規模效率。因此如果要改善整體行動通訊產業的經營效率,可以針對規模效率方面來做改進。(2)本研究實證發現,「資產總額」、「研究支出」、「員工素質」、「行動電話用戶數」及「行動電話通話費產值」等五項指標與經營效率值有正向的顯著影響關係。顯示出國內相關行動通訊公司對於上述之五項指標,要以積極與穩健的方式經營。
This study has collected inputs and outputs data form three telecommunications companies in Taiwan, and analyzed the operational efficiency by used Data Envelopment Analysis. Furthermore, this study examines the relationship between operational efficiency and technical innovation by using Mann Whitney U test. As this study indicated (1) the average overall technical efficiency of telecommunications companies in Taiwan is 85.5% and the remaining 14.5% still can be improved. The inefficiency comes from the scale. Therefore, if the overall efficiency in the telecommunications companies needs to be improved, it can focus on the scale. (2) All assets volume , reaserch outlay , employees’ qualities , the numbers of mobile phone users , and the benefits from bill of mobile phone , are obviously positive correction with the efficiency to operate a business. This study has shown that telecommunications companies in Taiwan have to have a positive and steady management in this four indicators .
