中文摘要：

基于2002年和2007年的投入产出表，测算了知识密集型服务业中流程创新溢出效应和产品创新溢出效应，并构建创新溢出网络，通过社会网络分析研究两种创新溢出网络的结构、活跃程度及其变化趋势，以及知识密集型服务业在其中功能地位的变迁．结果表明，知识密集型服务业对其他产业存在溢出效应．从溢出方式看，流程创新溢出效应大于产品创新溢出效应，但两者差距在缩小；从创新网络看，流程创新溢出网络的活跃程度和效率要高于产品创新溢出网络，产品创新溢出效应在不断提高；但其他产业对于创新溢出的利用率较为有限．知识密集型服务业虽然不是网络的中心，但是扮演着重要的创新源角色．所以应该从加强基础设施建设、平衡创新和溢出、促进企业良性竞争以及鼓励企业主动采用等方面采取措施促进创新溢出．

英文摘要：

It measures the process and product innovation spillover of KIBS based on 2002 and 2007 input-output table, and builds innovation spillover network, analyzes the structure, activity, trend and KIBS＇s status of network through the social network analysis. The results show that, KIBS have obvious spillover effect on other industries. Fromthe perspective of spillover pattern, process innovation spillover is greater than that of product innovation spillover, but the gap is narrowing. From the innovation network perspective, process innovation spillover network shows higher vitali-ty and efficiency than that of product innovation spillover network. The spillover effect of product innovation is on the increase, however, the utilization rate is still at low level. KIBS is not in the center of the network, but plays an impor-tant role of innovation sources. Therefore, administrations must pay attention to fundamental construction, balance in- novation and spillover, cultivate competitive market as well as encourage enterprises.
