Abstract: Abstract Identification and evaluation of urban center is one of the important contents of urban research and urban planning. Early development planning of Shenzhen focused on SEZ (special economic zones), which led to the polarization of SEZ and non-SEZ in the urban center system. With the help of spatial big data, limitations of traditional data are broken. Based on this, spatial pattern of Shenzhen central structure is analyzed, and then the evolution characteristics of Shenzhen central system are summarized. Using POI data of Shenzhen from 2010 to 2019, we comprehensively consider the influence of functional density and functional diversity on the determination of urban center, and measures the spatial structure of urban center in Shenzhen based on a simple and intuitive method to identify urban center. The research shows that the urban center based on POI data identification can better reflect the actual urban development. The urban center system of Shenzhen is in a growth trend, gathered in SEZ and transitional zone in the middle of Shenzhen and continuously expanding to the north of Shenzhen. The period from 2010 to 2015 is the fastest growing period of the urban center system in Shenzhen. From the perspective of urban macro level, spatial pattern of the urban center structure of Shenzhen shows the overall characteristics of moving from agglomeration in SEZ to balanced development within the whole urban, and the difference in the centrality level between SEZ and non-SEZ gradually decreases. Through the evaluation of existing plans, it is found that the urban planning of Shenzhen has played an important role in reconstructing the urban spatial structure and guiding the formation and development of the urban sub-center system outside the special zone.
