一般企業的物料採購成本平均約占公司營運總支出之50%，加上物料採購作業流程相當冗長且繁雜。因此，如何簡化採購流程及節省採購成本是企業一直以來所必須面對的重要課題，而電子化採購已成為企業採購原物料的市場趨勢。準此，本研究旨在探討電子化採購、夥伴關係、資訊分享、供應鏈整合，以及供應鏈績效等構面之間的影響。研究方法首先針對3家製造業進行個案分析，再對研究雛型與假設作適當的修正，接著進行第二階段的量化研究，以作為研究模式的最後驗證與確認。從個案研究與統計分析結果顯示，電子化採購可促進資訊分享與供應鏈整合。同時資訊分享與夥伴關係、供應鏈整合及供應鏈績效具有正向關係，可知資訊分享在電子化採購系統中扮演非常重要的角色。另外，夥伴關係依不同的產業而有不同的重要性，對某些產業而言，價格與品質才是重要的考量因素。個案分析與統計研究的結果比較大的不同在於，供應鏈整合對供應鏈績效的影響在個案分析中有顯著的關係，但在統計上的結果為不顯著。可能的原因有二：為了建立完善的供應鏈整合機制可能要花費不可估計的成本，而且效益是難以衡量的。另一方面;當供應商的溝通績效加強，但不一定影響到營業績效。

The average manufacturing firm spends about 50% of its sale revenue on the purchases of goods and services. Furthermore, the process of traditional procurement system is lengthy and complicated. Therefore, how to simplify procurement process and reduce procurement cost has always been a key challenge for enterprises.
E-procurement is a new trend to apply for solving the procurement problems. This research investigated the correlation between e-procurement and supply chain performance. Moreover, this study probed into some important factors of partner relationship, information sharing, and supply chain integration within supply chain system, as well as their roles and correlations within the framework. The current study adopted qualitative method to do case studies with three manufacturing firms and the original research model and hypotheses were revised, based on the results of case studies. Followed by that, the study used quantitative method to confirm and verify research model.
The results revealed that e-procurement could promote information sharing and supply chain integration. Furthermore, information sharing was positively associated with partner relationship, supply chain integration and supply chain performance. The information sharing, therefore, played an important role in e-procurement system. In addition, partner relationship held different importance from industry to industry. Moreover, in some industries, price and quality are the most important issues. The results of case study showed that, partner relationship only supports e-procurement, supply chain integration, and supply chain performance partially. However, the results of statistical analysis showed that partner relationship was not significantly associated with e-procurement and supply chain integration, and by improving the partner relationship may promote supply chain performance. Although the results of case study indicated that supply chain integration was positively related to supply chain performance, there was no significant correlation found between both through statistical analysis. There might be two reasons. To build complete and perfect supply chain integration may also spend inestimable cost and the benefit is hard to measure. On the other hand, while the supplier’s communication performance is enhanced, the supplier’s operational performance is not affected.
