ASUAD SANEN, Normand Eduardo  and  SANCHEZ, José Manuel. An exploratory and comparative analysis between bottom-up and top-down approaches for a spatialized construction of a regional Input-Output matrix. Rev. mex. econ. finanz [online]. 2018, vol.13, n.2, pp.137-174. ISSN 2448-6795.  https://doi.org/10.21919/remef.v13i2.273.

The purpose of this paper is to explore and apply a methodology for the construction of a regional spatial input-output matrix, using a bottom-up approach, compared to the top-down of the Sonora 2008 regional matrix. We use the methodology proposed by Flegg for the estimation of regional matrixes, spatializing it with limited information. In addition, we compare the two regional matrixes constructed by identifying the type of productive sectors, their economic links and multiplier effects, highlighting the application of the statistical method of principal components. It should be clarified that the spatialized analysis of input -output matrixes has not been addressed in the literature hence the importance of its analysis. The results show either at spatial and sectoral levels, that the sectors and economic structure that come from the regional matrix constructed from bottom-up approach are theoretically and statistically coherence, contrary to what happens with the regional matrix constructed from top-down approach, which allow us to conclude the importance of considering economic space as a fundamental element in the construction of regional input-output matrices.

Keywords : Regional input-output matrixes; bottom-up approach and top-down approach; R15.
