The upgrade of urban core from central business district (CBD) to Central Activities Zone (CAZ) becomes a trend that many cities in China follows, yet it turns out to be ambiguous during the specification of its boundary. This project proposes a relatively clear definition of CAZ through a comparison with CBD and then innovates a method to identify the potential CAZ in a city based on evaluated point of interest (POI) dataset. Taking Shanghai as an example, we first go through the background of CAZ, and decompose its concept, we propose a data process to calibrate the degree of functional mixture in aspects of retail, catering, office, leisure, culture, and recreation. Through the compilation of rasterized maps, we find the top fourteen dynamic places in downtown Shanghai and deliver three scenarios for the discussion of CAZ boundary. Moreover, this replicable method has already been applied in many planning practical analysis and documents.
