The night-time economy serves as a pivotal engine driving consumption upgrading, and the identification of its spatio-temporal differentiation laws is of great significance for optimizing urban resource allocation. Taking the six central districts of Tianjin as the study area, this paper integrates social media data with the Spatial, Temporal, and Space-Time Scan Statistics Software (SaTScan) spatiotemporal scan statistics method to systematically reveal the spatio-temporal dynamic characteristics of night-time economic activities. The main conclusions are drawn as follows: (1) Night-time economic activities exhibit significant seasonal fluctuations, with the intra-day activity showing a single-peak distribution. (2) The spatial pattern of night-time economic activities presents a gradient characteristic of core-periphery, where Heping District and its surrounding streets have a high level of activity. (3) The cultural and tourism belt along the Haihe River and transportation hubs reflect the waterfront economy mode and transportation-oriented mode, respectively, and there are significant differences in the intensity and duration of night-time economic activities across different time periods and locations. This study can provide methodological and case support for research on urban night-time economic vitality.
