Compact and dispersed cities: From the perspective of coexistence and sustainability

The purpose of this work is to compare and analyze the two opposite urban development models of compact city and decentralized city through five axes, and determine which model is most suitable to promote urban coexistence and sustainability. Therefore, this paper makes a literature study on the coexistence and sustainability of cities and the characteristics of the two urban development models of compact cities and decentralized cities. The two models are compared and distinguished through five axes, so that they can be compared under the variables of coexistence and sustainability. In the most revealing survey results, it pointed out that compact cities are the most appropriate urban development model. Therefore, under the principles of compatibility, solidarity and sustainability, cities are not only a “living space”, but also a “space for living together”. The main conclusion is that in order to achieve urban coexistence and sustainability, a relevant urban development model and citizen commitment are needed
