Environment and Planning B: Urban Analytics and City Science, 49(1), 58–75
Read publication ↗Research question
Can a common data source identify urban subcenters consistently across hundreds of cities?
Geographic scope
284 Chinese cities
Evidence base
Point-of-interest data and nonparametric urban analysis
Approach
A nonparametric method extracts concentrations of urban activity from ubiquitous point-of-interest data and compares patterns across cities.
Why it matters
The study offers a scalable way to describe polycentric urban structure when detailed conventional employment data are unavailable.
