摘　　要：运用超效率DEA模型对2009—2013年河南省18个省辖市的城市效率进行测度,并对城市效率水平时空演变特征进行分析,采用空间自相关方法对2013年河南省城市效率发展水平空间差异进行了研究.结果表明:12009—2013年河南省城市效率发展水平整体呈现出"中西高-东南低"的特点,豫中、豫西地区的城市效率相比要高于豫东和豫东南地区;2河南省城市效率发展水平具有一定的正空间相关性和空间异质性,即城市效率水平相似的地区在空间上集聚分布,说明城市效率水平不仅仅取决于各地区自身的发展程度,还受相邻地区城市效率水平的影响.In this paper,we employed super efficiency DEA model to give a quantitative research on the urbanefficiency,and analyzed the evolutionary characteristics of the temporal-space of 18 cities in Henan Province from2009 to 2013. Through the method of spatial autocorrelation,we studied the spatial differences of the efficiencylevel in 2013. The results showed sa follows. 1The level of urban efficiency presented that the characteristics of＂mid-western high and south-east low＂from the year 2009 to 2013,namely the urban efficiency level in the mid-western region of Henan Province was higher than that in eastern and southeast regions of Henan Province. 2Thelevel of urban efficiency had a certain positive spatial correlation and spatial heterogeneity in Henan Province,namely the space distribution was agglomerate in the cities that had similar urban efficiency level. This illustrated thaturban efficiency level not only depends on the degree of each region＇s own development,but also was influenced byadjacent urban efficiency level.
