The Influence of Supervisors' Co-authorship Network on Doctoral Research Output

Abstract

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
