我们对1992年至2014年的军事化国家间争端(MID)数据进行了时间网络分析。MID通过一系列事件取得进展,每一个事件都从一个国家对另一个国家的威胁到使用军事力量。我们将这些事件建模为一个时间冲突网络,其中节点表示状态,有向边表示事件。我们分析了冲突网络中的时间图案或子图,以揭示不同国家相互参与和升级冲突的模式。我们发现,不同类型的时间图案出现在网络中的时间尺度被认为是(天到月)和冲突的一年。在1周的时间尺度上,最常见的3边时间图案对应于两个国家对第三个国家采取行动的不同变体,这可能会使冲突升级。具有往复性的时间母题,即一个国家对先前事件的反应,往往只发生在较长的时间尺度上(例如几个月)。我们还发现,网络的度和时间基序分布是非常重尾的,少数国家参与了许多冲突。
We present a temporal network analysis of militarized interstate dispute (MID) data from 1992 to 2014. MIDs progress through a series of incidents, each ranging from threats to uses of military force by one state to another. We model these incidents as a temporal conflict network, where nodes denote states and directed edges denote incidents. We analyze temporal motifs or subgraphs in the conflict network to uncover the patterns by which different states engage in and escalate conflicts with each other. We find that different types of temporal motifs appear in the network depending on the time scale being considered (days to months) and the year of the conflict. The most frequent 3-edge temporal motifs at a 1-week time scale correspond to different variants of two states acting against a third state, potentially escalating the conflict. Temporal motifs with reciprocation, where a state acts in response to a previous incident, tend to occur only over longer time scales (e.g. months). We also find that both the network’s degree and temporal motif distributions are extremely heavy tailed, with a small number of states being involved in many conflicts.
