During 2016–2018 rapid urban renewal has taken place within Beijing inner city. Scientifc understanding of the regional differentiations and driving mechanisms of current urban renewal will improve strategy of the functional extraction and renewal policies. In this respect, we have used points of interest (POI) data and cellphone signaling data to analyze the urban renewal patterns based on several pattern identifcation and spatial analysis methods, including spatial intensity analysis, dominant pattern analysis and cooperativity analysis. On the basis of this, four types of urban renewal mode and their combinations are distinguished, including all POIs renewal dominated, restaurant renewal dominated, transportation and warehousing renewal dominated, transportation and warehousing renewal dominated with restaurant renewal assisted. Furthermore, according to the division of regional occupational–residential functions and regional population activity, four forms of basic regional conditions were obtained: balanced inactive area, balanced active area, employment active area, and residential active area, which well explains the formation mechanism of urban renewal heterogeneity. Lastly, the comparison between urban renewal what happed in Beijing and other cities is made, so as to put forward aspects concerning improved strategy of the functional extraction and urban renewal.
