近年來，台灣的公部門經歷了組織精簡、繜節成本、流程再造等多項對於公共服務品質的挑戰，在諸多改革課題中，植基於資訊科技創新的電子化政府與電子商務—以數位科技方式來完成商品、勞務的買賣及金錢匯兌的一項機制—乃兩項最為人矚目的世界性潮流。
在電子化政府與電子商務兩項理念的結合下，經由網際網路來公佈政府採購資訊及完成政府採購事務的政府採購電子化系統已在2000年於我國開發完成並上線服務。其中，電子領投標系統為政府採購電子化系統的四個子系統之一，此系統的目標是使有意競標的廠商在領標投標的過程中省卻大量的紙本作業，同時大幅提昇政府部門採購業務的行政效率，此外，透過線上競標公開化、透明化的程序，也能有效遏止採購弊端的發生。
本研究的目的如下：
1. 檢視世界各國政府採購電子化方案的發展與推行成果；
2. 分析及探討影響我國「電子領投標系統」發展與推行的關鍵因素；
3. 針對我國「政府採購電子化」這項政策的推行提出策略性建議。
在本研究中，我們首先論及電子商務的本質與近來發展，並介紹近來世界各國所推動的各項政府採購電子化系統、他們如何推動以上系統以及以上系統如何改革該國的政府採購業務。緊接著，根據我國電子領投標系統的相關情境背景，我們提出一個以計畫行為理論(TPB)為基礎，結合科技接受模型(TAM)與終端使用者滿意度(EUCS)解構的研究模型，以實證資料加以驗證，分析出該模型中影響電子領投標系統終端使用者使用行為意向的關鍵因素分別為有用性(U)、正確性(AC)、便利情況(FC)、態度(AT)、主觀規範(SN)及知覺行為控制(PBC)。最後，根據本研究之分析結果，提供相關建議，望能協助我國的政府採購電子化政策順利推動，進一步達成預期的政策目標。

Public services in Taiwan have experienced redundancies, cost cutting, closure of operations, and challenges to the quality of their services to diverse populations. Among the tasks of electronic government, electronic commerce, a mechanism of buying and selling goods and services, and transferring funds through digital communications, is the most visible trend of the information technology related changes over the last few years. Accordingly, the electronic government procurement system, an internet-based service for electronic government purchasing and information sharing, has been developed and provided to the public since 2000. Ideally, with the help of Electronic Tendering System, a subsystem of the electronic government procurement systems, tremendous paper work will no longer be necessary for companies doing business with government, and the administrative efficiency will be improved significantly. In addition, under the design of online biding procedure, the chance of procurement fraud may be limited as well.
The purposes of this paper are as follows:
1. Discuss the ongoing promoting programs of electronic government procurement internationally.
2. Analyze the key factors of the establishment and implementation of the Electronic Tendering System locally.
3. Propose strategies for the implementation of the electronic government procurement system.
In this paper, we discuss the essence of electronic commerce and introduce the international opportune movement for government departments to reinvent their organizations by implementing electronic procurement systems. In particular, we examine the antecedents of the technology usage in the context of an integrated model. Answering what the key factors of the successful information systems are is crucial to the development an effective electronic government procurement system program.
