現今，許多公司與他們的供應商夥伴建立跨組織資訊系統交換資訊、給予對方更快速的回應，以在快速變遷的環境之下維持競爭力。此篇研究進行文獻探討之後，分別從流程觀點還有動態能力觀點這兩個研究理論的基礎之下建立了研究架構，來衡量跨組織資訊系統的績效。我們的研究架構提出，一間公司有兩個重要的動態能力，分別是供應鏈的整合能力還有協調能力，在資訊科技的投資上還有公司績效之間扮演相當重要的角色。 / 我們在台灣的PC產業中發行問卷來衡量此研究架構，利用線性回歸來驗證假設。實驗結果支持了論文中的兩個假設：(1)跨組織資訊系統正向影響動態能力，(2)供應鏈的整合能力在跨組織資訊系統投資還有公司績效中間扮演重要的中介角色。 / Nowadays, firms usually develop inter-organizational systems (IOS) with their suppliers to exchange information and give each other faster responses to sustain their competency under a fast-changing environment. This study reviewed past literature and developed a research framework to evaluate IOS performance based upon two theoretical perspectives: process view and dynamic capabilities. This framework proposed that firms’ dynamic capabilities-- supply chain integration capability and supply chain coordination capability might be an important mediator between IOS investment and firm performance. / A general survey is conducted in Taiwan PC industry to validate the research model. A linear regression is used to testify the hypotheses. The results support our two hypotheses: (1) IOS investment is positively related to the dynamic capabilities, which also have obvious impact on firm performance; (2) supply chain integration is an important mediator between IOS investments and firm performance, and on the other hand, firm performance is partially mediated by supply chain coordination.
