本文从多层关系网络视角出发，构建基于论文和专利的多层科研合作关系网络。通过对燃料电池论文和专利数据的实证研究发现：多层科研合作关系网络相比论文合著网络和专利合作网络，能更好的反映各个机构之间的科研合作关系，识别科研合作网络中有重要影响力的节点，为我国企业推荐技术合作者提供帮助。通过对论文合著网络、专利合作网络、多层科研合作关系网络三种网络中介中心性的分析，发现在论文合著网络和专利合作网络中的重要节点，在多层科研合作关系网络中同样发挥着重要的作用，并且三种合作网络的中介中心性曲线都服从Zifp Pareto分布。%In this paper, a multi layered scientific research cooperation network is established from the perspective of multi layered relation network. By studying periodical thesis and patent literature on fuel cell technologies, this paper reaches a conclusion that: compared with periodical thesis coauthor network and patent cooperation network, the multi layered scientific research cooperation network can better reflect scientific cooperation among various institutions and more easily identify influential nodes in the network, thus providing help in recommending technology cooperator to enterprises. With analysis of betweenness centrality of the mentioned three networks, it is also found that many important nodes in the former two play the same significant role in the multi layered scientific research cooperation network and betweenness centrality curves of the three are all subject to Zifp Pareto distribution.
