1. Introduction

This book focuses on a recent model of “urban evolution,” which has already been outlined and developed in other volumes (Dalla Longa 2007, 2010). The reference urban model is CoUrbIT (Complex Urban Investment Tools) and is centered on the interconnection of urban functions that need to be redesigned. The boost in redesigning has been generated by globalization. This strong boost in redesigning affects (1) urban models; (2) the different kinds of relationships between public and private sectors in order to face the implosion caused by the rapid change of functions inside urban structures; (3) the new tools required; and (4) the new forms of “drive” required to govern these changes. The recovery of the competitive advantage of the urban systems within the international framework is at the bottom of these variables. One of assumptions states that, during the globalization stage, the most appropriate urban systems are the ones capable of guaranteeing the most competitive margins of their national or subnational reference systems (Normann 2001; Castells and Hall 1994; Castells and Himanen 2002).
