导师合著网络对博士生科研产出的影响

摘要/Abstract

摘要：

博士生是我国科研创新的重要力量，本文将从导师合著网络的角度探索提升博士生科研产出的对策。我们构建了139名理科博士生就学期间的导师合著网络，分析了博士生及其导师在导师合著网络中的特征，以及它们对博士生科研产出的影响。主要结论如下：博士生的合作规模与其科研产出呈倒U形关系；博士生在其导师合著网络中的程度中心性有助于其科研产出；导师网络的程度中心势调节博士生程度中心性与科研产出的关系，导师的中介中心性调节学生程度中心性和学生科研产出的关系。最后，我们就科研管理提出相关建议。

Abstract:

Doctoral graduates are important manpower of science and technology innovation in our country. This paper aims to explore the strategy of improving doctoral research output from the perspective of supervisors' co-authorship network. Based on the supervisors' co-authorship network we trace out from 139 doctoral graduates during their Ph.D learning period, we analyze both the doctoral graduates' and their supervisors' characteristics of supervisors' co-authorship network, and empirically studies the influence of the characteristics of network on doctoral research output. The main conclusions include: an inverted U-shape relationship exists between doctoral graduates' size of co-authorship network and their research output; doctoral graduates' degree centrality of co-authorship network benefits their research output; supervisors' degree centralization of network moderates the relationship between doctoral graduates'degree centrality of network and research output; supervisors' betweenness centrality of network moderates doctoral graduates' degree centrality and research output. Finally, suggestions about science and technology management are discussed.

Key words: co-authorship network, doctoral graduate, research output, degree centrality, betweenness centrality
