In this study a model is proposed of the process of core formation in urban structure. The model sets out to explain: (a) Why and how a core is formed in the first place, (b) How the form and structure of the core change through time, and (c) What the relationships and interdependencies are between the core and the rest of urban structure.
The thesis of the book is that authority relations provide meaningful complementary explanation for core formation in urban structure, together with the conventional parameters of transport costs, land values, and the like. More particularly, the hypothesis holds that changes in patterns of authority are significant causes of changes in urban core structure.
