摘 要:
该研究基于项目反应理论的Samejima等级反应模型（GRM），在MULTILOG软件支持下，应用参数检测方法，对某年度全国性资格考试的某科目试卷中经济法部分的21个项目做了DIF检测分析。结果如下：存在性别DIF的项目一个，存在民族DIF的项目四个，存在工作性质DIF的项目一个。其中项目68在民族层面上表现为一致性DIF，项目64既存在民族DIF又存在工作性质DIF。通过对项目统计量、反应曲线的分析和专家的讨论，文章最后还分析了产生这些DIF的几个可能的原因。[著者文摘]

Abstract:
In this study, based on the response the 21 optional item of the laws pertaining to the economy in some year intermediate economic test throughout country, a parametric procedure using the Graded Response Model and MULTILOG was used to detect DIF. The parametric procedures research found：4 items showed nation- related DIF;1 item showed gender- related DIF; and only 1 item showed work classificationrelated DIF. Nation - related DIF （item 68） is a uniform DIF and item 64 appears both nation - related DIF and work classification - related DIF.
