摘要：According to the influence graphs theory, the determinant of an input-output matrix is a good indicator of the global influence diffusion through an economic structure. The theorem of the loops and circuits [Lantner, in Dietzenbacher & Lahr, 2000] shows that this determinant can be calculated from a combination of substructures called Hamiltonian Partial Graphs (HPGs). Then the aim of this paper is first to give prominence to the fact that influence diffusion depends on the internal arrangement of the structure and second to show that all these substructures (HPGs) do not have the sae weight in the computation of this economic influence diffusion. The paper deals with the number of HPGs in a full graph and give proof of the particular importance of the short circuits for the diffusion of influence.
