中文摘要：

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。
