Abstract:

Quantifying the development of global cities and understanding their growth patterns can provide important guidance to planning and management of future cities. Here, we propose a quantifiable scaling-based framework for evaluating the development of global cities. We examined the global urban development from 2000 to 2015 in three dimensions that are critical to the sustainable development of cities. They are the gross domestic product (GDP), built-up area (BUA), and CO2 emissions. We find a universal pattern that the intensity growth of cities presents an inverted U-shape curve. In each dimension, cities at intermediate economic levels experience the most rapid intensity growth, which serves as the dominant driver of the city’s development.
