结构方程模型的特点及应用

大型工程建设项目伴随着国内经济发展而大幅增加，因而对其社会稳定风险的识别、评估及预警显得尤为迫切。有别于常规的风险识别及整体评估方法，针对关联风险因素内在关联关系的研究，有助于厘清社会稳定风险构成原理、构建预警管理体系。采用问卷调查法获取数据，经分析后构建结构方程模型（SEM），再结合评估所得的风险因素，针对某大型机场建设项目社会稳定风险实证应用该分析方法，定量分析风险构成及大小，完善社会稳定风险评估路径。

Conceptualising social impacts

Major construction projects increase with the development of social economy, which desiderate its social stability risks' recognition, evaluation and prevention. Research on associated risk factors' inner relationship differs from common risk recognition and evaluation, which contributes to the analysis of social stability risks' construction as well as building prevention management system. Questionnaire survey method was adopted in data collecting while structural equation modeling (SEM) in model building. Finally, with the basic of risk factors, a major airport construction project's social stability risks was put forward, whose construction and measurement can be analyzed quantitatively, so as that assessment path be completed.
