ABSTRACT={An influence graph is the representation of a flow structure in the economic dominance theory. We adapt the notion of a maximum spanning tree to the context of influence graphs for a single impulse node. We experiment on international trade flows with this tool in order to calibrate it. We conclude that the selected tree correctly synthesizes the main dependency relationships of the structure despite its very small contribution to the total dependency. Finally, we discuss the adaptation of the tool to the analysis of technological flows.}}
