Abstract
The night economy is an important representation of urban economic development and consumption level. Based on the night lighting, the data of the POI data, the data of the spatial clustering algorithm of DBSCAN、K-means and other spatial clustering algorithms and the study of the profit and loss of supply and demand, the model of the area and the area domain analysis of the night activity hotspot area and night service facility are established. The fusion of multi-source data provides a new perspective for the night economy, which is more rapid, efficient and extensive than the traditional survey data, which is suitable for the large-scale study of the night economy.
