Abstract: Appraisee’s Perception of Appraisal Politics (APAP) is the certain appraisee’s perception of political considerations, political behaviors and related organizational attributes’ influence on the appraisal result and benefits in the inter-subject relationships, constituting an important reflection intentional manipulation and intervention of performance appraisal. This paper utilizes descriptive scenario scale to measure the APAP in the public institutes of Pearl River Delta area. The result shows that interviewees have highly sensitive perception degrees of APAP to some of listed scenarios, with strong inclination of consistencies, but some others are opposite. Furthermore, interviewees at different ages and of different administrative rankings have significant divisions in terms of perception degrees of APAP. After excluding 4 scenarios of weakly perceived degree of APAP, the reserved 16 scenarios can be sub-grouped into 3 categories by explorative factor analysis: "Hierarchy", "System" and "Interaction", indicating that different rationales such as inter-agency relationship crossing hierarchies, internal systematical maintenances and direct superior-subordinate interactions could cause the changes of appraisal results.
