中文摘要：

基于创新系统理论与知识基础观，识别出知识型服务机构在创新系统中的关键角色，进而剖析知识型服务机构对制造企业创新的作用机制。通过结构方程模型分析发现：知识型服务机构通过影响制造企业的知识搜索、知识获取，最终作用于制造企业创新，且知识搜索与知识获取之间存在着替代效应。理论贡献在于通过角色识别剖析了知识到创新的转化机制，明确了制造企业与知识型服务机构的联结，知识搜索、知识获取与制造企业创新之间的内在联系；实践意义在于制造企业应清晰识别知识型服务机构的角色，借助知识型服务机构促进自身创新，突破现有发展瓶颈。

英文摘要：

On the perspective of innovation system theory and knowledge-based view, the article wants to identify the main role that knowledge-intensive business services play in the innovation system, and explore the mechanism that knowledge-intensive business services influence the innovation of manufacturing finns. Based on the SEM analysis, we found that knowledge-intensive business services can influence knowledge search and know- ledge acquisition, which will then influence the innovation of manufacturing firms. And knowledge search and knowledge acquisition have the substitution effect with each other. The theoretical contribution of this paper is that exploring the transition mechanism between knowledge and innovation, and defining the interrelationships among knowledge-intensive business services, knowledge search, knowledge acquisition and innovation of manufacturing firms. The practical implication is that manufacturing firms should explicitly identify the role knowledge-intensive business services play, and promote innovation with the assistance of knowledge-intensive business services
