Fig. 7: Range of risk propagation for different α/β values in the tungsten chain trade network with Canada or China as the risk source.
From: Supply risk propagation in international trade networks of the tungsten industry chain
a The risk propagation range of Canada as a risk source for different α/β values in the tungsten ore trade network. b–e The risk propagation range of China as a risk source for different α/β values in the corresponding tungsten trading network. γ = α/β. The variation in avalanche size is reflected in the line charts.
