This book focuses on investigating a smaller-scale urban phenomenon - creative hubs - as a basic geographic concentration unit of urban creativity. The purpose of the research is to put forward the concept of creative hubs as an urban mechanism that partially emerges spontaneously however with necessary planning intervention from the need of effectively leveraging local resources to better facilitate creative activities and ultimately prosper local economy. Building a conceptual framework that articulates the three essential components (the 3Ps) of creative hubs: people, place, and planning, the research further analyzes the creative-hub distribution in Toronto, Canada by using a mapping approach to illustrate how different creative hubs are scattered in the city.
