We propose here a quantitative analysis of the historical development of a large urban area by investigating the spatial distribution and the age of commercial activities in the whole city of Rome. We find that the age of activities of various categories presents a very interesting double exponential trend, with a transition possibly related to the long-term economical effects determined by the oil crisis of the Seventies. The diversification of commercial categories, studied through various measures of entropy, shows, among other interesting features, a saturating behaviour with the density of activities. Moreover, different couples of commercial categories exhibit over the years a tendency to attract in space. Our results demonstrate that the spatio-temporal distribution of commercial activities can provide important insights on the urbanisation processes at work, revealing specific and non trivial socio-economical dynamics, as the presence of crisis periods and expansion trends, and contributing to the characterisation of the maturity of urban areas. info:eu-repo/grantAgreement/EC/FP7/318132/EU/multi-LAyer SpAtiotemporal Generalized NEtworks/LASAGNE info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.806 2016 MULTIDISCIPLINARY SCIENCES 15 / 63 = 0.238 2016 Q1 T1 1.236 2016 Agricultural and Biological Sciences (miscellaneous) 2016 Q1 Medicine (miscellaneous) 2016 Q1 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Strano, Emanuele Nicosia, Vincenzo Porta, Sergio Latora, Vito 2003 395 Universidad de Zaragoza Dpto.
