Collaboration network analysis for the Arctic issues based on a collection of international collaborative events

In recent years, global warming has accelerated the melting of Arctic ice. The value of the Arctic has been increasing in various aspects and has received widespread attention from the international community. The significance of globalization of the Arctic issue has become more and more prominent, the member states of the Arctic Council, observer states, and non-Arctic countries that have intensively developed and updated their respective Arctic strategies have actively participated about Arctic issues. The international collaboration has gradually become an effective way of addressing Arctic issues. In order to explore the pattern behind the collaborative events about Arctic issues, with the application of complex network analysis, the international collaborative events about Arctic issues from 2013 to 2023 are selected to construct the collaborative networks. Then the collaborative networks are quantitatively analyzed by the relevant parameters of complex network. These parameters for quantitative analysis include network density, average path length, clustering coefficient, degree centrality, closeness centrality and betweenness centrality. The results of the study reveal the changes in international collaboration about Arctic issues from 2013 to 2023.
