No hay una propuesta que mida de manera exclusiva la infraestructura sectorial y que sea aplicada a nivel local, por lo que se hace necesario contar con una métrica con ese objetivo.  Metodología: El estudio se estima a través del promedio ponderado de diversos indicadores, ensayando la idoneidad de la muestra mediante pruebas y técnicas de análisis multivariado, y calculando los pesos específicos de cada indicador a través de componentes principales. Además, presenta una estratificación de los mismos con base en su nivel relativo de equipamiento. Se valida la propuesta por medio de la estimación econométrica de una relación positiva y significativa con tres indicadores de progreso económico.  Resultados: El índice compuesto que se estima genera una medida diseñada exclusivamente para detectar el avance o rezago en la dotación de infraestructura.  Conclusiones:  Se aporta un índice cuantitativo para determinar la infraestructura de telecomunicaciones con que cuentan las entidades de México, el cual es útil para el diseño de políticas públicas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  Background: Telecommunications services are provided with infrastructure that has a multifactorial character and that is relevant for its impact on economic performance and, therefore, on employment and the standard of living of the population. To date there is no proposal in the academy, which exclusively measures the infrastructure and has been applied at a local level. The purpose of this study is to define a quantitative index to determine the sectoral infrastructure that the different states in Mexico have.  Methodology: The index is estimated through the weighted average of indicators, proving the suitability of the sample through tests and multivariate analysis techniques, and calculating the specific weights of each indicator through principal components.  Results The estimated composite index allows for a measurement designed exclusively to detect the advance or lag in infrastructure provision.  Conclusions: An index to determine the sectoral infrastructure at state level is estimated. This measurement provides useful information for the definition of specific public policies.]]></p></abstract>
