因應供應鏈之間激烈的競爭，國內資訊電子業不但導入企業資源規劃以整合其內部企業流程，更導入跨組織資訊系統以便與外部夥伴，包括供應商、協力廠和客戶之間能緊密連結，以改善跨組織企業流程的協調和效率。 在供應鏈管理的跨組織資訊系統文獻中，大部分在探討中心廠的績效，對於整體供應鏈網路績效甚少著墨。Struab等在2004發表以六個理論為基礎的網路組織績效模型，並以兼顧程度和對稱性的資訊分享和組織依賴關係來衡量一對一的供應鏈網路組織績效。本研究即採用Straub 等的研究模式和資料分析方法，以國內的資訊電子業為對象，透過問卷調查探討中心廠和供應商間程度對稱的資訊分享和組織依賴關係與供應鏈網路績效的關係。研究結果發現，程度對稱的資訊分享和組織相賴關係不但顯著地正向影響一對一的供應鏈網路組織績效，兩者間的互動分析進一步顯示高程度對稱的資訊分享所帶來的網路組織績效始終高於低程度對稱的資訊分享所帶來的網路組織績效，其差異在相賴程度低的情況下更加顯著。 To cope with the severe competition between supply chains, the domestic IT industry not only employs enterprise resource planning to integrate internal business processes, but also introduces inter-organizational system (IOS) to tightly linked to various partners including vendors, suppliers and clients to improve coordination and efficiency of inter-organizational business processes. While prior studies of the IOS in SCM have examined the benefits of network leaders from these systems, little attention has been paid to the performance of the supply chain as a whole. To measure the performance of a supply chain, Struab et al. (2004) proposed a nomology of networked organizational performance (NetOP) based on six theories. They successfully established that degree symmetric information sharing and degree symmetric interdependence positively affected the performance of the dyadic supply network. This study adopts the research model and data analysis of Straub et al., regards domestic IT industry as the target, examines the relationship between the degree symmetric information sharing and interdependence and NetOP. The results show that degree symmetric information sharing and interdependence not only positively affect the performance of the dyadic supply network, the interaction between the two antecedents reveals that high degree symmetric information sharing always leads to higher performance than low degree symmetric information sharing, and the difference is more significant when the degree symmetric interdependence is low..
