What do divided cities have in common? An international comparison of income segregation
基于12个国家城市的小尺度网格收入数据，用空间熵指数比较收入隔离水平，发现更大、更富裕、生产率更高且更不平等的城市隔离更严重，高收入家庭隔离最突出，多中心城市中生产率与隔离的正向关联被削弱。
Abstract This paper provides a comparative assessment of income segregation in cities of 12 countries. We use spatial entropy indexes based on small‐scale gridded income data and consistent definition of city boundaries to ensure international comparability of our segregation measures. Results show considerable variation in the levels of income segregation across cities, even within countries, reflecting the diversity within urban systems. Larger, more affluent, productive, and more unequal cities tend to be more segregated. Urban form, demographic, and economic factors explain additional variation in segregation levels through the influence of high‐income households, who tend to be the most segregated. The positive association between productivity and segregation is mitigated in polycentric cities.
