中部崛起背景下安徽省城镇化效率时空分异特征

Spatial-temporal Pattern of Urbanization Efficiency in Anhui Based on the Boom in Central China

基于中部崛起的战略背景,以安徽省为例,综合利用DEA模型、Malmquist指数、GIS趋势面分析及空间统计模型等方法对2000—2014年安徽省城镇化效率进行综合评价及时空分异研究。结果表明:(1)2000年后安徽省城镇化效率总体上呈现不断提升的态势,技术进步变化是推进城镇化效率增长的主动力,3个时间断面均呈现出效率东西方向递增、南北方向倒"U"型分布形态。(2)城镇化效率在全局空间均表现出较显著的集聚分布,即城镇化效率高(低)的地域空间相毗邻;城镇化效率局部热点区形成"合肥—芜湖"核心区,且不断向周边马鞍山、滁州等地演化,而城镇化效率冷点区主要集聚在皖北地区,形成"哑铃型"分布格局。(3)地理区位、产业结构及区域政策是影响2000年后安徽省城镇化效率时空分异的主要因素。

Taking Anhui Province as the research object,comprehensively using the improved DEA mode,Malmquist index,trend surface analysis and spatial statistical model methods,the paper preliminary evaluated urbanization efficiency and analyzed spatial-temporal differentiation pattern in Anhui from 2000 to 2014. The results showed that: urbanization efficiency showed a tendency of ascension,all the three time sections had presented eastwest direction increasing and south-north direction having the inverted "U-shaped"distribution pattern; the urbanization efficiency had a positive correlation characteristics,there existed a spatial cluster feature,which means that the regions with high urbanization efficiency intensity were apt to be adjacent to the regions with high urbanization efficiency intensity; and the regions with low urbanization efficiency intensity were apt to be adjacent to the regions with low urbanization efficiency intensity; urbanization efficiency hot area were mainly distributed in the Hefei-Wuhu region,after 2007,Maansahn evolved into hot zone,urbanization efficiency cold spots area mainly agglomerated in the northern of Anhui,spatial distribution was stability. Geographical location,industrial structure,policy factors were the main factor affecting the spatial pattern of urbanization efficiency from 2000 to 2014.
