中文摘要:
      结构方程模型(SEM)被归类于高等统计学范畴中,它整合了因素分析与路径分析两种统计方法,可同 时检验模型中包含的观测变量、潜在变量(不可观测变量)、干扰或误差变量间的关系,进而获得变量与因变量 的直接影响、间接影响或总效果值,可用来进行复杂的多变量研究数据探究与分析。梳理了 SEM 的数理意义、 建模过程及其在合并村庄脆弱性形成机理研究中的应用方法,深入揭示合并村庄脆弱性之潜在变量脆弱性扰 动、敏感性、适应力、可持续发展能力及其对应的观测变量义务教育、基础设施、政民互动、养老保险等因素的作 用过程,估算了观测变量的因素负荷值、直接或间接影响效果值,为合并村庄脆弱性风险防范提供重要决策参 考。鉴于 SEM 在合并村庄脆弱性形成机理研究中的应用,还对 SEM 在地理学其他研究领域的应用做了展望。
英文摘要:
      Structural equation model (SEM) is classified into the category of advanced statistics,integrating the two statistical methods of factor analysis and path analysis. SEM can test the relationship among dominant variables (observed variables),latent variables (unobserved variables) and disturbing or error variables contained in the model at the same time,and then obtain the direct influence,indirect influence or total effect value of variables and response variables,used for exploring and analyzing complex multivariate research data. This paper summarized SEM’s mathematical and physical significance,modeling process,as well as application methods in the research on vulnerability formation mechanism of the merged villages,deeply revealed the interaction between latent variables of vulnerability of the merged villages (such as vulnerability disturbance,sensitivity,adaptability and sustainable development capacity) and their corresponding observed variables (such as compulsory education,infrastructure,interaction between the government and the public,endowment insurance and other factors),and estimated the factor loadings and the direct or indirect influence effect value,providing an important decision-making reference for the risk prevention of the merged villages. In view of the application of SEM in the research on vulnerability formation mechanism of the merged villages,this paper also forecasted its application in other research fields of geography.
