Abstract:	隨著企業廣泛地運用資訊科技於企業營運活動，使得國內企業的運作模式、效率與市場互動上明顯改變。然而，企業之資訊科技投資，除了與營運活動直接相關的應用系統之外，還包括提供分享式服務給應用系統的IT基礎建設。而如何正確地投資IT基礎建設，已經成為企業能否有效益地使用資訊科技的重要課題。本研究從應用系統之「穩定型」和「演進型」這兩個特性類型觀點，檢視不同特性類型應用系統的IT基礎建設彈性需求，並以上述觀點導出本研究的四個研究命題。接著，以個案研究的方式，選擇四家導入資訊科技於企業營運之台灣機械產業的企業，進行深入的實證分析。研究結果顯示演進型應用系統的IT基礎建設所有元件之彈性必須是高度水準的假設，並未受到實證企業支持，並非每一個元件都需要具有高度彈性，有一部份的IT基礎建設元件彈性可以偏低。另外，穩定型應用系統的IT基礎建設所有元件之彈性皆允許低度水準的假設，亦未受到實證企業支持，例如IT人員的彈性皆需具有高度彈性水準。結合理論與實証結果，本研究證實演進型和穩定型應用系統所需之IT基礎建設彈性的確不同，但並非極端地非高即低，而是一部份彈性需要高度水準，一部份彈性允許低度水準。本研究釐清的事實，不僅充實現有研究領域的不足，對於台灣機械產業的資訊科技運用，亦具參考價值。 Enterprise operation changes along with the interaction of the efficiency and markets and with widely use of the advanced information technology. Thus how to invest the IT infrastructure accurately has become a important subject. First we investigate various types of application systems with respect to the IT infrastructure flexibility. Four propositions have been developed. This research needs of then implements the IT technology to four Taiwan machinery companies. The results show that it is not necessary to have all components having high flexibility for IT infrastructure, neither do all components of stable application system IT infrastructure need lower level flexibility. In combination of the theoretical and real-case results, we verify that flexibility for evolving and stable application systems of IT infrastructure are different. The fact clarified from our research not only supplements the insufficiency of the present research but also a reference to the Taiwan machinery industry’s IT technology implementation.
