Abstract: We construct a DtSBM model,based on the existing Dynamic DEA model DSBM,which optimizes the term efficiency firstly. The model is applied for measuring the healthcare service efficiencies of China's 31 provinces through panel data from 2008 to 2015. By measuring the DMUs' term efficiencies and overall efficiencies,we verify that the China's new medical and health system reform,which was acted in 2009,has obvious effect from the perspective of efficiency. And we result that the efficiency scores of eastern region is the highest,western region is the second,and central region is the lowest. According to the analysis of the inefficiency DMUs,we also figure out the improved orientations and objectives.
