幾年前，大多數的企業都熱衷於改善內部作業流程並導入ERP；然而近幾年，企業越來越重視將供應鏈管理、顧客關係管理與供應商關係管理納入決策考量之內，因此，組織間對於B2B的交易與協同作業已逐漸受到注意。而電子採購(e-procurement)即為B2B交易流程與協同作業之一種。
尤其是現今的製造業為因應日益激烈的競爭，需要更具彈性的組織快速回應市場、更短的產品生命週期以及更多樣化的產品去迎合顧客需求；而動態的資源配置與更有效率的原物料採購流程也將使產品製造更具彈性。因此，企業導入電子採購系統成為必然的趨勢，而導入電子採購系統後，首先面臨的問題是效益發生在哪裡？目前相關研究大多是以個案研究評估單一廠商之效益，較少以量化研究提出一整合模式同時針對供應商與買方評估其績效，所以，企業應如何評估電子採購系統所產生的效益乃成為一重要課題。
本研究的主要目的是探討以網際網路Web-based的電子採購系統為平台，透過此採購系統，對買方與供應商個別的作業產生哪些直接影響，並為雙方帶來什麼樣的效益。同時也要探究電子採購系統對買賣雙方之關係在哪些方面有相關的影響。事實上，買方與供應商對於導入電子採購系統之目的並不相同，導致所產生的效益也不盡相同，若能透過問卷調查做一有效評估，相信有助於電子採購之推動。經由本研究證實，電子採購系統的確會透過雙方合作程度與直接影響因素替供應商與買方帶來一定的績效，能帶給企業許多效益。

Until several years ago, organizations mainly focused on optimizing business processes within organizational boundary. Enterprise Resource Planning (ERP) software had been a hot issue for companies to improve their operations. Towards the end of last century however, organizations increasingly included supply chain management, customer relationship management, and supplier relationship management in their roadmap for implementing information technology. Business-to-business (B2B) transactions and collaboration between organizations have received increasing attention. E-Procurement is an important issue of B2B transaction and collaboration.
Stiff competition, fast changing customer preferences, shortening product life cycle, and product variety proliferation have pushed modern manufacturing industries to be more flexible to cope with their environments. Along with dynamic capacity allocation, efficient material procurement forms a pillar to support flexible manufacturing. Therefore, the implementation of e-procurement system in enterprise is an inevitable trend. Then the next issue comes to what benefit occur from e-procurement system? Most past research have addressed the benefit issue based on the case study of single enterprise. Little investigation has conducted quantitative research to assess the performance with respect to supplier and buyer. How to estimate the impact on performance for both of buyer and supplier as a result of implementing e-procurement system is the research issue addressed in this project.
Given the web-based e-procurement system as the enterprise procurement platform, this research attempts to address the direct impact on business processes for buyers and suppliers simultaneously, and subsequently to evaluate the impact on performance for them. In addition, this research also intends to investigate the impact on relationship between buyers and suppliers. In fact, the motivation of supplier in implementing e-procurement system might be different from that of buyer, leading to different results which might occur. The questionnaire survey conducted in this research can help to evaluate the performance for buyers and suppliers.
