摘    要:运用数据包络分析(DEA)方法,采用2006~2011年甘肃省12个地级市的建成区面积、全社会固定资产投资、第二、三产业从业人数投入指标,建成区绿地面积、居民人均可支配收入以及第二、三产业产值作为产出指标,对甘肃省12个城市土地利用效益进行评价。结果表明,从甘肃省区域发展战略来看,“两翼”城市土地利用效率较高,而“中心”城市土地效率较低,呈现“两边高中间低”的空间分布形态;从城市发展特征上看,陇东和河西以能源化工以及新能源和新能源装备制造业为主的城市土地利用效率高于传统工业城市;从城市规模上看,中小城市的土地利用效率高于大城市。

关 键 词:数据包络分析  城市土地利用  效率评价  甘肃省

Abstract:By using data envelopment analysis (DEA) method, built-up area, total social investment in fixed assets, number of employees in second and third industry 4 indexes as inputs indicators, built-up green land area, residents per capita disposable income and two or three in- dustrial added value 4 indexes as output indicators, the land use efficiency of 12 cities in Gansu Province during 2006-2011 was evaluated. The results showed that from the point of regional development strategy in Gansu Province, "two wings" urban land use efficiency is higher, and the "center" urban land efficiency is lower, presenting the spatial distribution of "both sides are higher than middle " ; seeing from the ur- ban development characteristics, the land use efficiency of the urban that give priority to energy chemical industry, new energy and new energy equipment manufacturing industry in Longdong and Hexi area is higher than traditional industrial city; seeing from the urban size, small and medium-sized city land use efficiency is higher than big cities.
Keywords:Data envelopment analysis (DEA)  Urban land use  Efficiency evaluation  Gansu Province
