The remarkable development of the Information and Communication Technologies (ICTs) has changed every single aspect of our lives, emotionally and mentally. Through the application of Bayesian spatio-temporal analysis to aggregate mobile phone data of Shenzhen Municipality, China, the primary goal of this research is to analyze urban dynamics of Shenzhen, China, based on the numbers of mobile phone users in a 24-hour period and discuss a class of Bayesian hierarchical models that simultaneously characterize spatial and temporal patterns. Specifically, our purpose is a) to explore the overall relationship between aggregate mobile phone users and time at a small-area level and b) to identify the geographic variation of area-specific trends and whether there is a spatio-temporal interaction effects and c) to pinpoint “unstable” areas showing evidence of unusual variability in the time pattern of human mobility, such as hot spots and cold spots in the mobile phone data. The results may helpful for the planning and provision of municipal facilities and services. Further time-varying or space-varying coefficients could be considered in the future, allowing for different effects of covariates in time or space.
