In this work, we propose a new lecture of input-output model reconciliation Markov chain and the dominance theory, in the field of interindustrial poles interactions. A deeper lecture of Leontief table in term of Markov chain is given, exploiting spectral properties and time to absorption to characterize production processes, then the dualities local-global/dominance-Sensitivity analysis are established, allowing a better understanding of economic poles arrangement. An application to the Moroccan economy is given.
