Abstract: S&T intermediary is an important carrier to optimize the configuration of innovation resources of the cluster , but its specific form of effect is transformed dynamically along with the change of the surrounding environment of the cluster. By collecting the data of 41 transformation and upgrading demonstration area in Zhejiang Province, adopting QCA method to analyze the function of the role of S&T Intermediary in different network structures, it is found that the mechanism of the influence of S&T Intermediary on cluster development can be divided into three types, including co-equal network knowledge dissemination model, intensive network knowledge dissemination model and fragmented network bridge model , the bridge plays a fundamental leading role in all modes. In addition, limited by the total amount of resources and the level of industrial development, diversification of business development of S&T intermediary relying on the innovation chain cannot yet play a significant role in promoting the development of cluster. The result of research provides an effective reference for the rational design of the development path of S&T Intermediary and the optimization of the configuration of scientific and technological resources in cluster.

摘要： 科技中介是优化集群创新资源配置的重要载体，但其具体作用形式随着集群内周边环境的变迁而动态转化。通过搜集浙江省41个转型升级示范区的数据资料，采用定性比较分析方法对不同网络结构下科技中介所扮演角色的功能作用进行整合分析，研究发现，科技中介对集群发展的影响机制可以分为对等网络知识传播模式、密集网络知识传播模式和细碎网络媒介模式三种类型，其中媒介角色在所有模式中都发挥着基础性主导作用。此外，受限于资源总量和产业发展水平，科技中介依托于创新链的多元化业务拓展尚不能对集群发展起到显著的推动作用。研究结果为合理设计科技中介发展路径、优化集群科技资源配置提供了有效借鉴和参考。
