智慧資本作為策略性資源取代土地資本、原料資本與金融資本，成為企業價值創造的源泉。智慧資本的管理決定一個企業生存、調適和競爭的能力。在今日競爭激烈的環境，企業如何運用智慧資本創造價值並建立持續競爭優勢，已成為今日企業的重要管理議題。對於智慧資本內涵與存量的衡量，學者已提出許多不同的技術與方法，然而對於智慧資本管理效率的衡量仍相對不足。有鑑於此領域實證研究的相對缺乏，因此本研究之目的在於探討廠商管理與運用智慧資本之效率。

此外，本研究嘗試建立一多元投入與多元產出的績效衡量模式，評估企業在智慧資本存量及流量運用的績效。而績效主要在衡量資源被使用的程度，如何運用最少的資源，透過最佳的資源配置方式，獲取較高利潤，是企業管理者所關心的課題。本研究目的主要有兩點： 1.建構IC設計產業之智慧資本衡量與經營績效指標並分析其智慧資本運用效率。 2.分析IC設計產業智慧資本管理效率的變動狀況，並依據企業的相對效率與效率改變將其分類，使企業可據此瞭解相對於競爭者其智慧資本管理與運用的狀況並加以改善。

本研究採用資料包絡法與Malmquist生產力指數探討41家台灣IC設計公司在2002年的智慧資本運用的相對效率與1999年至2002年績效的改變狀況。透過客觀的數據分析，提供相關結論作為業界提升智慧資本運用績效時之參考。智慧資本的有效管理與運用將決定企業生存競爭之能力，本研究初步建構一智慧資本管理效率評估模型，研究分析發現多數企業的智慧資本運用效率仍有改善空間，而約三分之二企業的效率在4年中並未獲得改善，最後並依據企業的效率將其分類，使企業可據此瞭解其相對效率狀況，並作為企業改進與提升競爭力之參考。

Firms gain competitive advantage and superior performance through the acquisition, holding and subsequent use of strategic assets - both tangible and intangible assets. In the face of an intensely competitive environment, firms are challenged with the task of managing and leveraging intellectual capital. Although the importance of intellectual capital in assuring superior performance is well accepted, few studies have investigated the nature of relationship between those two variables. The objective of this study is to focus on the efficiency of firms at converting intellectual capital stocks into performance.

The purposes of this study are: (1). to establish an assessment model to measure the intellectual capital stocks of Taiwan IC design companies, (2). to evaluate and compare the performances of 41 IC design companies, and (3). to examine the efficiency change of 41 IC design companies from 1999 to 2002.

This study adopted data envelopment analysis (DEA) and the Malmquist productivity index to measure the performances of 41 Taiwan IC design companies in 2002 and the efficiency change from 1999 to 2002. The results revealed that about one third of the companies have excellent efficiency of managing intellectual capital. But the efficiency of two thirds of companies is getting worse from 1999 to 2002. Moreover, the entire industry can be partitioned into six clusters based on relative efficiency of managing intellectual capital and efficiency change. It is expected this study can provide useful information for future research in alternative contexts.
