近年來，研究廠商創新之觀點，從以往之產業群聚移轉至網絡演化，然而，影響網絡形成與演化之因素於以往探討廠商創新能力的相關文獻中較少受到關注，而合作，即為網絡關係的一種型態。從個體的角度觀之，廠商的合作行為往往面臨資訊不對稱的情形，因此本研究從廠商資訊不對稱的觀點出發，引入管理學門中訊號理論(signaling theory)的觀點，解構廠商訊息以及廠商過去所累積的社會資本與研發合作網絡建立之關聯性。並探討不同型態的空間地域屬性對於合作網絡的形成是否有所影響。 本研究以台灣ICT廠商為研究對象，該產業不僅在我國經濟發展的過程中扮演重要的角色，於世界的資訊科技產業鏈中亦占有一席之地。並且有著技術上需要持續創新，並且注重分工合作的特性。資料蒐集採用二手資料的方式，建立近似於整體性的廠商技術網絡資料以及廠商基本屬性資料，分析方法以社會網絡分析法、Pair-t檢定以及卜瓦松迴歸模型進行假說驗證。實證分析結果顯示廠商訊息的揭露對於合作網絡的建立有正面影響效果，並且廠商對於研究發展的相關訊號-研發資產的投入，有助於吸引其他廠商和其建立合作網絡的關係；而廠商於過去累積的網絡地位亦有助於合作網絡的形成。最後在空間地域屬性方面，實證結果顯示空間地域屬性對於廠商合作網絡的建立存在影響效果，創新氛圍較強的產業地域有助於廠商研發合作網絡的建立；此外，廠商若位於高網絡密度的產業群聚內部亦有助於其建立合作網絡，顯示廠商區位的挑選對於其外部網絡關係存在影響效果。 / In recent year, the research topic of firm's innovation is transformed from industry cluster to network evolution. However, the factor of network evolution was less mentioned in past research , and the cooperation activity is one type of network relationship.From the perspective of the individual , firm often faces the condition of information asymmetry , while cooperating with others. So our research begin with this problem, and we introduce signaling theory to understand the relation between R&D alliance and firm’s signal or social capital and also discuss whether different types of geography character have the effect on R&D alliance formation. This research concerns Taiwan’s ICT industry as study object. Taiwan’s ICT industry not only plays an important role in Taiwan’s economic development but also is a key part of the global ICT industry chain. Besides, ICT industry has the character of technical innovation and work division, so the firm’s cooperation behavior is important.We use secondary data to build the database, using SNA, pair-t test and poisson regression to analyze. The result shows that the information reveals a positive effect on alliance formation. In addition, firms investing in the property of research and their accumulating of network position in the past have the positive effect on R&D alliance formation. Finally, the result also shows that firm located on high-innovation and high network density environment is more easily to help them find the R&D alliance partner. It shows that firm’s choice of location affects the outside network relation.
