结构方程模型在系统综合评估指数中的应用

Application of Structural Equation Model in Synthesis Evaluation Index

文章提出采用结构方程模型建立多指标系统评估指数模型。该方法可以方便地研究每一个隐变量与其显变量集合之间的关系,并且可以分析各隐变量与综合评估指数之间的联系,得到一个既能综合各隐变量、又能很好地代表系统中所有指标变量的综合指数。论文以中国城市发展水平评估为例,采用了反映经济水平和生活水平的两个变量组,将结构方程模型用于建立城市综合评估指数,对不同城市进行综合评价排名,得到的结果与一般的经济地理知识十分吻合,验证了模型的有效性。

Based on the structural equation model, a synthesis evaluation method is discussed. The relation between every latent variable and its corresponding observed variables is investigated and the relation between every latent variable and the multivariable evaluation index is analyzed with the proposed method, Therefore, the multivariable evaluation index which represents the latent variables and observed variables is computed with this method, The urbanization development level model of Chinese cities adopted two variable sets which reflect economic level and living level, and structural equation model is applied for establishing city synthesis evaluation index, The result showed consistence with economic geography.
