網際網路及電子商務的出現，大大的改變了企業看待採購的方式，以及企業如何去面對與供應商間的關係。由於現今的競爭已由企業間轉變成供應鏈間的競爭，電子採購的導入無疑是企業增加供應鏈競爭力的重要一環。以鋼鐵之大型企業而言，更必須由複雜之採購程序當中跳出，進一步去思考如何以電子採購去創造策略性採購的價值。
本研究選擇以傳統鋼鐵產業的MRO供應商為標的，來探討其加入電子化採購之意願因素，以及所能產生的效益影響加以評估分析。由於電子採購是一個相對新的資訊科技的運用，因此現有創新擴張理論可以有效用來探索供應商採用電子採購的意願因素。
本研究彙整過去關於創新採用新科技的文獻，以「產業環境面特性」、
「組織面特性」、「電子採購科技面特性」之三構面做為探討供應商採用電子化採購之意願架構；另以「供應商夥伴關係」及「供應商績效」之兩構面來探討採用因素對於供應鏈績效的影響。
研究結果顯示，供應商認為在依賴買方資源下會增加電子採購的採用意願，且供應商認為有權力的買方如果使用強制權力會影響供應商的採用意願。供應商普遍認為高級主管支持對於電子採購的導入與採用是很重要的因素。另外供應商如認為電子採購可以降低公司商業交易的成本、改善公司現金流量時，則採用意願變高。當中心廠佔供應商銷售金額的比例以及採購頻率愈高時，表示此中心廠算是供應商的一個重要顧客，為了與之保持良好的夥伴關係，便會配合中心廠導入電子採購。
另外，本研究經由迴歸分析驗証，供應商接受電子採購採用的因素中，對於供應體系競爭力影響最大的因素為信任，然本研究也發現，供應商若考量電子採購可能會降低其獲利時，其感知的信任對於供應商之作業績效的影響性會降低。因此，電子採購之交易機制的擬定，必須能提供一個公平公開的交易平台的環境，使得供應商能融入組織文化中，將品質的要求與組織的目標一致，才能使供應鍊的績效能提昇且進一步能得到保障。
最後本研究並也根據研究結果，對供應商及中心廠分別提出電子採購採用的建議。

The view of procurement and partnership management with the supplier has been drastically changed for many enterprises, because of the emergence of Internet and Electrical Commerce in the present age. The way of competition between enterprises has been combined into the supply chain. We believe that the implementation of e-procurement will contribute to the increasing of gross profit, benefit and competitiveness undoubtedly. For the big firm like integrated steel mill, it is definitely necessary to simplify the complicated purchasing procedure, so that the tactical issue of e-procurement just can create high value from the procurement.

In this thesis, an Innovation Adoption model is proposed to study the e-procurement adoption intention by MRO supplier of Taiwan’s steel industry, and it’s impact on supply chain also has been evaluated.

Based on relevant research, the Innovation Diffusion adoption model in the thesis is proposed, which is composed of three major perspectives including environment, organization, and e-procurement technology factor. Besides, related issues in each perspectives are also addressed. Furthermore, two perspectives of partnership and achievement of supplier are also proposed to study the impact of the performance of supply chain.

The conclusion of this research indicates that supplier will increase the intension of adopting e-procurement depends on buyer’s resource support as well as buyer’s coercive power. In addition, top management support of supplier is a important factor for the adoption. Besides, market share and transaction frequency in the e-procurement represent buyer being a significant customer will enforce the will of supplier to corporate with buyer to adopt e-procurement.

Furthermore, result from regression analysis shows that Trust is major influential factor for the performance of supply chain. However, influence of Trust will be reduced, because of perceived cost being emphasized. The transaction mechanism of e-procurement should provide a fair and transparency transaction platform, so that supplier will corporate to enforce the performance of entire supply chain.

According to the research result, some of the advisements for the supplier and buyer were also discussed in thesis
