摘　　要：高校基建工程从立项到竣工投用需要多个单位跨专业合作,其间关系复杂,网络化趋势明显。本研究运用SNA理论和方法,建立高校基建合作网络模型,基于案例分析其网状拓扑结构特征,并以此为DBSCAN算法指标将案例聚类。结果表明:大型基建工程和资质完备的咨询、建筑企业是合作网络中常见的核心节点;“核心局域网个数”及“中心化程度”是两个合理的分类维度。本研究对高校基建管理者提出相关建议,一定程度上丰富了高校基建管理理论。From project approval to its completion,an university infrastructure project needs the cooperation of multiple units across specialties.The relationship between them is complex and the networking trend is obvious.SNA theory and method are used to establish the model of university infrastructure cooperation network,and the characteristic of its network topology structure are analyzed based on cases,which is then used as DBSCAN algorithm index to cluster the cases.The results show that large-scale infrastructure projects and qualified consulting and construction enterprises are the common core nodes in the cooperation network;the number of core LANs and the degree of centralization are two reasonable classification dimensions.The research puts forward relevant suggestions for the university infrastructure managers and enriches the theory of university infrastructure management.
