隨著網際網路的普及，電子商務開始蓬勃發展，而企業對企業間的電子商務更是被認為在未來會成為電子商務中最主要的部份。供應鏈管理為企業對企業間電子商務的應用之一，供應鏈管理其主要目的在使整個供應環節運用整合性的作業方式以及和諧式的經營理念，提供一個低成本、高效率、高彈性、以及能快速回應的競爭優勢。由於電子商務的發展，可以幫助公司減少供應商的數目及協助企業夥伴，電子商務和供應鏈管理的整合也正在改變企業的內部作業以促進彼此合作，運用電子商務整合產業上中下游的供應鏈管理將成為企業競爭利器。 　本研究透過實證研究的方式，實際用問卷調查國內的資訊產業，觀察其電子商務應用與供應鏈管理績效間的相關性，希冀透過本研究來瞭解電子商務應用程度的多寡是否會影響供應鏈管理的績效，並進而對企業提出更具體的建議。 　本研究的兩個主要目的為：(1)探討電子商務應用與供應鏈管理績效間的關係，(2)探討企業特性是否會對電子商務應用與供應鏈管理績效間的關係造成影響。從研究結果顯示出，電子商務應用與供應鏈管理績效間有顯著的正相關，在企業特性方面，研究結果發現組織的型態不會影響電子商務應用與供應鏈績效間的關係，但組織的規模則會影響電子商務應用與供應鏈績效間的關係。 / Along with the widespread use of Internet, E-commerce starts to expand prosperously. Business-to-Business (B-to-B) E-commerce is considered the most important part in the future E-commerce, and Supply Chain Management (SCM) is one of the applications in B-to-B E-commerce. The main purpose of SCM is to offer a low-cost, efficient, quick and flexible competitive advantage by the united operational method and the harmonious management concept for the whole supply segments. Owing to the development of E-commerce, it can help the company reduce the number of the suppliers and form an alliance among the business partners, when integrating E-commerce and SCM. It also will change the internal operation of industry to improve mutual cooperation of industries and become a competitive weapon for the business by the unification of up, middle and down streams of SCM through E-commerce. 　This research is to investigate the relation between applications of E-commerce and performance of SCM through empirical study by the practical questionnaire of Taiwan's information industry. Through the research, we hope to understand the influence of applications of E-commerce to the performance of SCM and to offer concrete suggestions for business enterprises. 　There are two main purposes in this study. Firstly, we want to study the relation between applications of E-commerce and performance of SCM. Secondly, we want to find out if the characteristics of the business enterprise will influence this relation. From our study, we find out that applications of E-commerce and performance of SCM are heavily related. We also find out the type of the business organization will not influence the relation between applications of E-commerce and performance of SCM, but the scale of the business organization will.
