Abstract

Resumen: El Índice Relativo Industria-Ciudad (IRIC) es una formulación que permite clasificar el grado de intensidad de la actividad productiva en las áreas urbanas españolas mediante el cruce analítico de diversas variables referidas al empleo industrial, la superficie de suelo industrial y el porcentaje de población activa. La aplicación de este índice nos ha permitido definir y clasificar tipologías de ciudades medias industriales en España en un estudio previo. Partiendo de este análisis, en este trabajo se plantea la necesidad de consolidar esta investigación analítica, reforzando la definición del perfil de la ciudad media industrial española y su caracterización con un número discreto de variables. En este artículo se analiza la estructura del IRIC obtenido, se plantea un nuevo modelo mediante el algoritmo PCA y se comparan ambas versiones. Se realiza asimismo un pequeño análisis de sensibilidad del índice y se establece el grado de alteración de las variables iniciales, obteniendo cambios de posición de las ciudades industriales en la red urbana española. Finalmente, mediante técnicas de clustering se refuerza el perfil del carácter industrial de las ciudades medias, contribuyendo a destacar la relevancia productiva que tienen este tipo de áreas urbanas. Abstract:The Industrial-Urban Relative Index (IURI) is a formulation that allows the classification of the degree of intensity of the productive activity in the Spanish urban areas by means of the analytical crossing of diverse variables referred to the industrial employment, the surface of industrial land and the percentage of workforce. The application of this index has enabled the definition and classification of typologies of medium-sized industrial cities in Spain in a previous study. Based on this analysis, this paper considers the need to consolidate this analytical research, reinforcing the definition of the profile of the medium-sized, industrial Spanish city and its characterization with a discrete number of variables. This article analyzes the structure of the IURI obtained, suggests a new model using the PCA algorithm and compares both versions. A small sensitivity analysis of the index is also carried out and the degree of alteration of the initial variables is established, obtaining changes in the position of the industrial cities in the Spanish urban network. Finally, by means of clustering techniques, the profile of the industrial profile of medium-sized cities is reinforced, contributing to highlighting the productive relevance of this type of urban areas.
