领导成员交换对主管评估行为的影响研究

近年来，评估者行为成为绩效评估研究领域的新焦点，它会受到自身动机/ 特征、受评者特征、评估者与受评者二元关系、组织评估制度等多方面因素的影响。本文设定主管为评估者，选择评估者与受评者二元关系中的领导成员交换（LMX）作为主要研究变量，探究LMX 与主管评估行为之间的关系。通过231 份有效问卷数据统计结果发现，LMX 显著正向影响主管宽大评估行为，LMX 水平越高，评估结果越趋向宽大；反之LMX 显著负向影响主管准确评估行为，LMX 水平越低，评估结果越趋向准确。在研究中引入管理性评估目的作为调节变量，当处于低情境下的绩效评估管理性目的时，LMX 对主管评估行为影响与主效应保持一致，但处于高情境下的绩效评估管理目的时，无论LMX 水平高低与否，主管都会趋向采取准确评估行为。

The Influence of Leader-member Exchange on the Director Performance Appraisal Behavior

Over the past decades, rater behavior becomes the new focus of research in the field of performance evaluation, it will be affected by rater motivation or characteristics, ratee feature, rater-ratee issues, organizational system and so many factors. This paper chooses leader-member exchange as the main object to explore the relationship between leader-member exchange and director (principal rater/direct superior) performance appraisal behavior. This research finds that leader-member exchange has a positive significant effect on director leniency appraisal behavior and a negative significant effect on director accurate appraisal behavior through 231 valid questionnaires survey data. Administrative evaluation purpose served as an adjustment variable in the study,we find that when in a low-context performance evaluation management purposes, the effect of leader-member exchange on the director performance appraisal behavior is consistent with the main effect. But in the high-context of performance evaluation management purposes, regardless of the level of leader-member exchange, heads will tend to take an accurate appraisal behavior.
