 This paper examines the impact of urban sprawl on economic development in China's provincial capitals. The authors propose a new methodology for measuring urban sprawl, which takes into account both economic activity and spatial patterns. They find that urban sprawl has increased over time, but it is more severe in certain parts of the country than others. Additionally, they identify correlations between urban sprawl and economic factors, such as industrial structure, and built-up area form. This research provides valuable insights into how urban sprawl can be managed effectively in order to promote sustainable economic growth.
