This paper reviews the history and progress of time-dependent probabilistic seismic hazard analysis，and makes a simple prospect on its future development and application prospect. It declares that future study tendency on time-dependent probabilistic seismic hazard analysis will be reflected in the determination of seismicity model parameters，applicability and judgment rule of characteristic earthquake model，application of ideas of repeating earthquake，studies on factors of effecting the calculation of characteristic seismic hazard，recognition of seismic source segmentation on large structures and mechanism of adjacent structure interaction. Seismic risk assessment in a certain period，emergency disaster preparedness and earthquake insurance will be future application areas of time-dependent probabilistic seismic hazard in China.
