Research on Spatial Pattern and Influencing Factors of Consumption Vitality in the Middle Areas Based on POI data—A Case Study of Hefei City

This paper uses kernel density analysis and a geographic detector model to analyze the spatial pattern and influencing factors of consumption vitality in central cities, taking Hefei as an example. The results demonstrate that: (1) the spatial distribution pattern of five consumer service facilities basically presents the characteristics of “large agglomeration—small dispersion”. The central urban area forms a large continuous area, while the peripheral area forms a small independent area. (2) The spatial layout of Hefei’s consumption vitality shows the characteristics of multi-core high agglomeration in the new business circle and low-value small-scale agglomeration in the periphery area. (3) The spatial distribution of Hefei’s consumption vitality is the joint result of multiple influential factors such as economy, transportation, and social public services.
