The pivotal nodes in the world city network are global cities—cities of supreme strategic value in global economy and politics, science and technology, culture, and society. Global Cities: Past, Present and Future explores the evolution of global cities—their formation, rise, development and tendencies. This book summarizes and interprets global tendencies and also puts forward a theoretical framework that will help researchers understand these cities better. It also makes a compelling case for understanding every city in terms of evolutionary dynamics. The first eight chapters of the book discuss the ontology of global city evolution and patterns, forms and trends of development. The last two chapters study the case of Shanghai, which aims to build itself into an important global city by 2050. This case study illustrates the shaping of a new type of global city that demonstrates new characteristics of the globalized space.
Chapter 6: Evolutionary Model
On the basis of the evolutionary dynamics of global cities, we attempt to analyse how global cities evolve, namely how global cities demonstrate dynamics and diversity in the interaction of choices of locations and choices of the environment. First of all, a dominant model of evolution is constructed based on the evolutionary pathways of all global cities. Then, evolutionary diversity is elaborated based on the experiences of individual global cities.
To explain the formation and development of global cities in a general sense, it is essential to develop a basic theory based on a general review of the history of global cities. The next step is to examine the overall evolutionary process and characteristics.
