以資料包絡分析法評估ERP 系統導入後投資效能之研究

對於想要獲取商業利益及ERP系統效能的企業而言，資訊科技管理已經成為關鍵的因素之一。本研究使用資料包絡分析法來評估ERP持續投資與技術效率之間的關係；基於整體擁有成本的概念，本研究也利用Tobit回歸來分析技術效率分數與ERP持續投資之間的關係。本研究的結果顯示：（1） ERP系統的維護支出，對公司的技術效率有明顯的影響。（2）ERP人員的薪資支出，對公司的技術效率有明顯的影響。（3）ERP人員的教育訓練支出，對公司的技 術效率沒有明顯的影響。（4）對於持續投資ERP系統的公司而言，在技術效率上有正相關的影響。（5）對於在台灣導入ERP系統的公司而言，相較於國際品牌的ERP系統，本土的ERP系統顯示出較高的技術效率。
