摘　　要：目的通过对比SAS和LISREL软件在结构方程模型运算过程中的程序特点和结果差异,为结构方程模型应用者提供参考。方法运用SAS和LISREL,采用Monte Carlo数据模拟实验对预设模型进行分析。结果 SAS和LISREL对同一参数和统计量的输出结果相同;LISREL输出了更加丰富的拟合指数,并能提供较为直观形象的含有路径系数的路径图;SAS的编程语句直观明了,更易被具有计算机编程基础或者专业统计分析人员所掌握。结论应用者可按照自身专业背景和对两个软件使用的熟练程度灵活选择两种软件。Objective To provide the reference for the application of structural equation model through comparing procedure characteristics and results of SAS and LISREL in the computing process. Methods We analyzed the default model by using Monte Carlo simulation with SAS and LISREL. Results SAS and LISREL had the same output for the same parameter and statistic.LISREL provided more fitness index and visual path chart with path parameters.SAS had the simple procedures and was proper for professional statisticians or those who knew basic computer programming. Conclusions Appliers can choose one of the both software in accordance with their professional backgrounds.
