本文运用专家调查法确定了影响公安机关业务绩效的外部因素,在此基础上运用因子分析对这些相互之间关联的外部影响因素进行分析处理,在保留基本信息的基础上提取了4个公因子,用这些公因子替代外部影响因素进行多元回归分析,用回归残差作为比较业务绩效的基础。为公共部门绩效评估的横向比较提供了新的思路。 In this paper, we use the expert investigation method to determine the external factors that affect the business performance of public security agencies. Based on this, factor analysis is used to analyze and deal with the external factors that affect each other. Four common factors are extracted based on the basic information , Using these common factors instead of external factors for multiple regression analysis, using regression residuals as the basis for comparing business performance. It provides a new way for the horizontal comparison of public sector performance evaluation.
