DEA績效評估-以工業電腦產業為例

Abstract

台灣在全球工業電腦扮演不可或缺的角色。本論文以2006 年的營收規模為考量，挑選國內13 家工業電腦廠商，輔以國外2 家工業電腦廠商為研究對象，利用資料包絡分析法，進行2002 年至2006 年各廠商的相對經營效率及策略聯盟的效率分析，期能找出經營績效佳的廠商所具有的共同特質，提供業者在企業資源投入分配上改進之建議；另於第二階段，藉由Tobit迴歸分析，進一步探討影響工業電腦廠商之經營效率的因子。實證結果如下：

1. 國內IPC 公司經營效率優於國外IPC 公司 2. 專用型的小IPC廠商主攻利基產品，創造高效率、高獲利。 3. 通用型的大IPC廠商整合趨勢明顯，成長力道強勁。 4. 國內工業電腦業者可藉由策略結盟找到成長機會。 5. 資本額大、發展自有品牌、專注垂直市場等因子皆對於經營績效有助益。

Taiwan firms play an indispensable role in the IPC industry. This research utilizes the Data Envelopment Analysis (DEA) approach to evaluate 13 Taiwan domestic and 2 foreign IPC firms’relative efficiency during the period from 2002 to 2006. The purpose is to discuss the operating efficiency of IPC firms, and to explore whether performance better off via strategic alliances. In addition, some improvement guidance and suggestions are provided for operation units with less efficiency. Then through Tobit regression analysis method, several factors that affect the operation performance of IPC companies can be identified. The findings are as following:

1. Domestic IPC firms’operating efficiency is superior to foreign ones'. 2. Small IPC firms focusing on niche markets have enjoyed high profits. 3. Big IPC firms grow via integration. 4. IPC firms can find the growth opportunities through alliance. 5. According to the Tobit model, firms with larger capital, brand equities and going vertical have better performance.
