基于 SNA 的老旧小区改造 PPP 项目中脆弱性因素识别与防范

改造工作的顺利完成是老旧小区改造项目中各参与方共同的目标，然而实践中，老旧小区改造 PPP 项目众多参与方合作模式暴露出诸多脆弱性问题。通过文献综述与案例研究相结合的方法识别出老旧小区改造 PPP 项目脆弱性因素，将其脆弱性因素划分为 3 个维度， 构建出脆弱性关系邻接矩阵；运用社会网络分析方法对个体中心度和凝聚子群进行分析，确定核心脆弱性因素的聚类情况， 分析各脆弱性因素之间的影响关系； 并结合脆弱性因素间相互影响关系，针对聚类的核心因素给出相应防控措施。

Identification and Prevention of the Vulnerability Factors of Old CommunityRenovation PPP Projects Based on Social Network Analysis

The successful completion of the renovation work is the common goal of all participants in the old communityrenovation project. However， in practice， the cooperation of many participants in the old community renovation PPP project hasexposed many vulnerabilities. Through literature reviews and case studies， the vulnerability factors in the old community renovationPPP projects are identified. The factors are divided into three categories， and the adjacency matrix of vulnerability relationship isconstructed. Secondly， the social network analysis method is used to analyze the individual centrality and cohesive subgroups todetermine the clustering of the core vulnerability factors and explore the interactions among various factors. Finally， thecorresponding prevention and controlling measures are given for the core factors.
