This text presents a re-elaboration of the strategic planning of the mexican economy dynamic multisectorial model. The new version of the model involves a redefinition of three aspects. At the empirical level, the new national input output matrix forms the basis of information (INEGI, 2008). At the conceptual level, we incorporate a refinement of the behavior of the external sector, external debt and production. And, at the programming level, the computer simulation program is STELLA/IThink (9.0.1). As the model application we use the proposal of the federal government called “Program of Commercial Facilitation: A Structural Reform” (SE y SHCP, 2008), which aims to maintain the competitiveness of the industrial sector within a stage of total openness to all countries.
