The great changes of economy and technology initiate the times of service knowledgeization, then the new service industry,knowledge-intensive business service (KIBS), is emerged. And the innovation activities of KIBS are coming into the research field of innovation theory. However, when reviewing the literature about the KIBS, we find it basically uses the traditional manufacturing industry as the fundamental of innovation paradigm. Meanwhile we observe, if an innovation paradigm based on the manufacturing industry was simply transplanted to the KIBS, the false research result would appear since the ignorance of the difference between them. In this paper, some basic characteristics of KIBS have been analyzed in comparison to the innovation paradigm of manufacturing industry. Finally, the basic natures of the innovation paradigm of KIBS have been concluded.
