Investigating the Relationship between Inter-Organizational Systems Investment and Corporate Competitive Advantage: The Role of Supply Chain Dynamic Capability

從供應鏈動態能力觀點探討跨組織資訊系統與企業競爭優勢之關連性

雖然跨組織資訊系統投資一向在企業策略中被視為創造競爭優勢的利器，但許多企業在建置採用後發現這些跨組織資訊系統並沒有帶來預期的績效。當其他的競爭者也採用相同的跨組織資訊系統時，企業頂多能維持競爭力，而無競爭優勢可言。本研究提出『供應鏈動態能力』概念，並強調跨組織資訊系統又須要結合供應鏈動態能力才能創造組織的競爭優勢。根據流程理論及動態能力觀點，本研究提出兩項供應鏈動態能力，分別為供應鏈整合能力及供應鏈合作能力。本研究並以台灣個人電腦產業之145家公司為施測對象，經由線性迴歸分析發現供應鏈動態能力在跨組織資訊系統及組織競爭能力關係上扮演重要的中介角色。此外，本文也發現與供應鏈整合能力相較，供應鏈合作能力具較強之中介效果。

Many companies have developed strategies that include investing heavily in inter-organizational systems (IOS) in order to facilitate information sharing and sustain competitive advantage. These systems, treated as competitive weapons, are expected to provide great business value; however, many of them do not fulfill the expected promises. This study proposes that IOS can be a source of competitive advantage only when combined with supply chain dynamic capabilities (SDC). Built upon the process theory and the view of dynamic capabilities, the author defines two types of SDC supply chain integration capability and supply chain coordination capability. Conducting linear regression analysis on data collected from managers in 145 companies in the personal computer (PC) industry in Taiwan, the author shows that SDC play a significant role in mediating the effects of IOS investments on the company's competitive advantage. Furthermore, supply chain coordination capability has a greater mediating effect than supply chain integration capability on the relationship between IOS investment and competitive advantage. Thus, these findings confirm the influence of SDC on IOS investment and show which SDC is of primary importance to create competitive advantage for companies.
