为提升民航飞行安全管理水平，基于不安全行为影响因素的重要性，通过文献分析和相关者调查的方式确定不安全行为影响因素集合。根据调研数据，运用社会网络分析（SNA）方法构建了不安全行为影响因素间的关系概念模型，研究其节点属性、核心—边缘分析、结构特征、影响力及聚类等级情况。结果表明，关键不安全行为影响因素节点可构成行为连锁反应链，进而连接成具有较高风险性的行为网络。其中，关键不安全行为影响因素包括职业倦怠、安全监察、业务技能熟练程度；存在行为连锁反应链，包括“知识水平较低—规程标准不够严格—民航飞行不安全”等；不安全行为影响因素网络的桥节点包括职业倦怠、压力等。
To enhance the management of civil aviation flight safety, a set of factors influencing unsafe behavior is determined through literature analysis and stakeholder survey． Then a network model of relationship among these factors is built by applying social network analysis. Its node attributes, core-edge analysis, structural feature, influence and hierarchical clustering are investigated．The result shows that the key unsafe behavior influencing factor nodes can form a reaction chain, which can in turn connect with others into a high-risk behavior network. Among them, the key unsafe behavior influence factors include job burnout, safety supervision, and business skills proficiency. There is a chain of behavioral reactions, including "the level of knowledge is low- procedures are not strict- civil aviation flight is unsafe", etc. Some kinds of behavior such as job burnout, stress, etc. can serve as bridge nodes in the network of factors influencing unsafe behavior．
