Megacities and global cities. Urban size does not make urban function
Most megacities (more than 5 million inhabitants) are located in developing countries and a number of them have a weak global economic role, if any. Most global cities are in the developed countries and they are not always very large city. There is a form of divergence between the size of the cities and their economic role in the global economy. This paper proposes some avenues for understanding this mega-global divergence.
The Monocentric Model and After
International audience
Economics of contemporary cities
Pourquoi existe-t-il des villes ? Pourquoi les villes attirent, pourquoi elles repoussent ? D'où vient leur puissance économique ? Comment déchiffrer la croissance, l'étalement et la recomposition des villes ? Pourquoi sont-elles des lieux de communication, des portes ouvertes sur le monde ? Comment s'imposent les villes globales ? Ce livre propose des réponses à ces questions en faisant appel à l'histoire, aux faits contemporains et au raisonnement économique moderne exposé de manière simple et accessible. Il offre des clés pour mieux comprendre la ville du XXIe siècle.
In search of lost centrality
The major changes of economic space organization seem to cast doubt over the concept of centrality and its applications, especially at the city, city network and global economy scales. Urban sprawl gives rise to a diffused or multiple centrality. Economic globalization reorganizes material and immaterial flows, and redistributes economic power to the advantage of global cities. A precise analysis of the terms center and centrality and of the phenomena they refer to permits to show that the classical patterns, if they are properly adapted, remain relevant at the urban scale, but that new centrality patterns are emerging at the world scale, on a reticular basis.
