近十年來相關研究陸續強調影響已開發經濟體的主要趨勢之一，與『產業的服務化』有關，亦即在當代經濟發展中知識密集服務業比重逐漸增加且持續擴展。因此，本研究首先將嘗試探討在地區創新系統之演變中，知識密集服務業的角色與機能；其次，分析知識密集服務業廠商與其客戶二者間的互動關係，並從新竹和台南科學園區為核心之二地區創新系統演化中，解析不同階段的發展差異。研究發現，知識密集服務業的成長受到地區內對專殊化服務之整體需求的影響，使其在產業介面上逐漸扮演重要角色。而在不同地區創新系統演化過程中顯示，知識密集服務業廠商對客戶之功能，則逐漸由知識提供者角色轉化為共生角色。

In the last decade, relevant studies have gradually emphasized one of the major trends impacting developed economies, that is, the increasing importance and continuing expansion of KIBS in current economic development. Therefore, this study first attempted to explore the roles and functions of KIBS in the evolution of an area innovation system. Secondly, this study analyzed the actual interactions between KIBS firms and their clients, and the role difference of KIBS by examining the evolution of the local innovation systems separately centered in Hsinchu and Tainan Science-Based Industrial Park in Taiwan. Based on the result of this study, the findings are that the cumulative interactions led to increasing demand for and reliance on KIBS, prompted the emergence of needs for specialized support in many different functions, and resulted in gradually more important roles of KIBS firms in the industrial interface, that is, gradually transform into influential partners of their clients, and not merely knowledge providers.
