Macro Analysis of Urban Structure Based on Point of Interest

Abstract

Point of interest (POI) is the geographic entity to implement urban function. With the development of the city, the number of POI is exploding. We analyzed the POI's macro characteristic of 31 major cities in China. The results show that POI is strongly associated to urban macro economy. Many macroeconomic indicators are significantly positive correlated with the number of POI, especially regional GDP. Further comparative analysis on the proportions of different POI kinds reveals the development of urban structure is unbalanced and unreasonable.
