摘　　要：在企业员工绩效研究中,度中心性作为重要的社会网络结构变量受到极大关注,然而并未获得一致的结论,其原因是传统的度中心性指标难以揭示隐藏在相同度中心性背后的结构差异。为了揭示这种差异对个人绩效的影响,基于网络节点结构异质性,本文定义了一种新的网络指标——节点重要性。通过对2009年在西安市进行的组织结构与团队绩效调查数据分析,发现非正式网络相比正式网络会对员工的个人绩效产生较大影响,而"节点重要性"相比度中心性更能够反映个体在网络中的权利地位,进而影响其绩效。Degree centrality, as an important social network structure variable in the study of the performance of employees, has become a research focus. However, no common conclusion is reached from recent studies. The reason for this is that the classic degree centrality index can not reveal the structural differences of actors with the same value of degree centrality. To reveal the influence of the structural differences to employee＇ s performance, this paper defines a new network index named node importance according to structure heteroge- neity of nodes. Based on the data from investigation of organization structure and team performance of Xi＇ an in 2009, the results show the informal network, but not formal network, has a significant impact on employees＇ performance. Compared to the degree centrality, node importance can reflect the power of individual in networks, and affect the performance.
