Abstract

En el siguiente artículo abordamos el problema de medir las diferencias de digitalización que existen entre las Comunidades Autónomas de España. Partiendo de esta idea proponemos un índice sintético que permite cuantificar dicha diferencia, utilizándolo de dos maneras: la primera como medida del gasto en equipamiento en la especificación de un modelo para el uso de Internet en cuya estimación las variables más significativas resultan ser el gasto en equipamiento, la edad y el nivel de estudios; y la segunda para explicar los determinantes del nivel de digitalización de las CCAA. Para encontrar una especificación del segundo modelo utilizamos el algoritmo RETINA de Pérez-Amaral, Gallo y White (2003) en donde vemos como se mejora la predicción fuera de la muestra a partir de la inclusión de interacciones y pendientes específicas entre los regresores del modelo original.
