基于DtSBM模型的中国医疗卫生服务效率动态评价

在现有动态DEA模型DSBM的基础上，构建了时期效率最优的DtSBM模型，并以省（市）为决策单元（DMU）运用该模型对中国31省（市）（除港、澳、台）2008-2015年的医疗卫生服务效率进行动态评价。通过对各省（市）医疗卫生服务各时期的最优效率值（即时期效率）和所有时期的整体效率值（即整体效率）的测算，从医疗卫生服务效率的角度验证了中国自2009年开始正式实施的"新医改"具有显著效果；按东、中、西部区域划分时，东部医疗卫生服务效率最高，西部次之，中部最低；通过对决策单元各项投入产出指标需改进百分比的分析，提出了相对效率值较低的无效决策单元——山西省、黑龙江省、吉林省、辽宁省和陕西省改进其医疗卫生服务效率的方向和目标。

Dynamic Evaluation of China's Healthcare Service Efficiency based on DtSBM Model

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.
