长江中游城市群城市效率水平测度及空间分异研究

LEVEL MEASUREMENT AND ITS SPACE DIFFERENTIATION OF URBAN EFFICIENCY IN URBAN AGGLOMERATION IN THE MIDDLE REACHES OF THE YANGTZE RIVER

运用超效率DEA模型对2013年长江中游城市群城市效率进行测度评价。结果发现:长沙、天门、常德、黄冈、南昌、景德镇、武汉、娄底、新余、衡阳、仙桃、鄂州、潜江和九江为城市效率相对高水平区;抚州、湘潭、鹰潭、上饶、岳阳、黄石、荆州和株洲为城市效率相对较高水平区;萍乡、宜春、益阳、吉安、咸宁、孝感、襄阳、宜昌和荆门为城市效率相对低水平区。在此基础上,分析长江中游城市群城市效率的空间分异特征,发现长江中游城市群城市效率发展水平相似的地区在空间分布上呈现出一定的异质性特征,但并不显著。

This paper analyzed the urban efficiency of urban agglomeration in the Middle Reaches of the Yangtze River in 2013 with the DEA model.The result showed that：Changsha,Tianmen,Changde,Huanggang,Nanchang,Jingdezhen,Wuhan,Loudi,Xinyu,Hengyang,Xiantao,Ezhou,Qianjiang,and Jiujiang had a higher urban efficiency;Fuzhou,Xiangtan,Yingtan,Shangrao,Yueyang,Huangshi,Jingzhou,and Zhuzhou had a moderate urban efficiency;Pingxiang,Yichun,Yiyang,Ji＇an,Xianning,Xiaogan,Xiangyang,Yichang and Jingmen are located in the low efficiency level zone.Based on these,analyses on the space features of urban agglomeration found there existed moderately heterogeneous spatial pattern in the efficiency of urban agglomeration in the middle reach of Yangtze river city development level of similar area.
