中文摘要：

本文采用传统C2R及方向性距离函数模型，分别计算了中国31个省际地区城市医院医疗服务效率。两种模型下的测度结果都显示2005—2010年间中国城市医院医疗服务效率总体呈现明显区域特征，其中华北、东北和西部部分地区城市医院的医疗服务效率相对较低，而长三角、珠三角、东部沿海及中部地区的医疗服务效率相对较高。对比两类模型测度效率结果，同全国平均水平下的传统医疗服务效率相比，考虑患者支出因素的城市医院医疗服务效率相对更高；但个别如华北、东北和西北等地区，考虑成本因素后医疗服务效率出现了明显下降，说明这些地区存在着较为严重的过度医疗问题。

英文摘要：

This paper calculates the medical care service efficiency of urban hospitals of China＇s 31 provincial regions with traditional C2R and directional distance functions. The measurement results based on two models all instruct that the medical care service efficiency of China＇s regional urban hospitals shows obvious regional characteristics during 2005 - 2010. The medical care service efficiency of urban hospitals in North China, Northeast China and part of western regions is relatively lower, while the hospitals in Yangtze River Delta, the Pearl River Delta, the eastern coastal and the central regions have relatively higher service efficiency. From the comparison results of the two efficiency models, we find that, the medical care service efficiency of urban hospitals is higher if the factor of patients expenses is considered compared with the traditional medical care service efficiency. However, some urban hospitals in North China, Northeast China and Northwest China, because they obviously consider the cost factor, medical care service efficiency is lower, illustrating that the problem of excessive medical treatment is serious in these regions.
