創新來自知識的互動。本研究將創新知識來源分成客戶類知識與技術類知識，並將企業創新分成新產品開發、解決客戶問題與提高企業自身創新能耐，以探討知識互動特性對不同類型創新的影響。本研究針對業務端與研發端的知識互動，採個案研究的方式，蒐集14個企業創新個案。分析結果發現，高深度的知識互動是新產品開發成功的關鍵；不同客戶問題，所需的知識互動廣度與深度則不一；若欲提高企業自身創新能耐，需要的是高廣度的知識互動。本研究透過不同實際個案歸納出各類創新類型下的知識互動特性，除了有助於更加瞭解知識互動對創新的影響之外，亦有助於企業經營實務上的操作。 / The objective of this study is to understand the impact of intra-organizational knowledge interaction on business innovative performance. The study divided knowledge of innovation into customer-related knowledge and technology-related knowledge, and classified business innovation into product innovation, problem-solving innovation and general innovation capability. Focusing on the knowledge interaction between sales people and R&D engineers the study analyzed 14 business innovation cases in four selected companies. The results reveal that high depth of knowledge interaction is the key to product innovation while the level of the depth and scope of the knowledge interaction is highly related to the context of the problems to be solved. In regard to general innovation capability, high scope of knowledge interaction seems to be the influential factor. The findings about intra-organizational knowledge interaction provide insights about how different levels of the scope and depth of knowledge interaction affect different types of business innovation and offer useful guide in managing technology and customer knowledge in business practices.
