Abstract: This study describes the international collaboration of China based on bibliometric data of
internationally co-authored papers from web-of-science during 2007—2016, from which the international
collaboration network is generated. The global network properties are calculated, indicating the network
is not exactly the same as small-world model or scale-free model. The network structure properties of
countries, including degree centrality, closeness centrality, eigenvector centrality, constraint and tie strength,
are measured. The relationship between the network structure and highly cited papers is tested in negative
binominal regression model. The results of regression analysis are stated as follows: eigenvector centrality
is the most influential factor in promoting highly cited papers, and the next is tie strength; constraint
significantly hampers the output of highly cited papers, and the next is degree centrality; the effect of
closeness centrality is not significant.
