Abstract: In the last decades, great advances have been made in data collection, mining, geo-computerization, 3Ds visualization and space-time simulation and others aspects. Owing to these technological improvements, we are embracing a new research stage that data are increasingly multi-sourced, methods scientific, objects microcosmic and practical. In other countries, space-time research has exerted widespread influences on the theory of structuration, GIS and other social sciences. In China, followed by about 20 years' introduction and innovation, especially study on the interactive mechanism between urban space and space-time behavior, and explorative real- time data collection experiments using LBS, solid foundations have been laid to further our research towards application. We believe that space-time behavior studies have great potential application in urban planning, social governance, citizen services and other domains.

Key words: citizen service, social governance, space-time behavior, time geography, urban planning
