根据交通经济带理论,利用空间分析确定兰新铁路辐射带的精确辐射范围,以县级行政单元为研究对象,综合运用SPSS、GeoDA和ARCGIS分析区域经济时空差异后发现:兰新铁路辐射带区域经济差异有增大趋势;经济集聚性总体上呈减弱趋势;区域经济发展相对平稳;按照2010年区域经济发展水平综合指数,兰新铁路辐射带县级行政单元可分为:经济不发达地区、经济欠发达地区、经济较发达地区、经济发达地区;根据县级行政单元与其相邻单元的关系,将兰新铁路辐射带县级行政单元分为:扩散型、极化型、“沉陷”型、“传染”型;经济发展的热点区域位于兰州市和乌鲁木齐市,经济塌陷区位于兰新铁路辐射带的东南部,区域经济发展沿兰新铁路,呈“点-轴”渐进式扩散。
According to the theory of transportation economy, the precise radiation range of Lanzhou-Xinjiang railway radiation belt is determined by spatial analysis. Taking the administrative unit at the county level as the research object, the spatial-temporal differences of regional economy are analyzed comprehensively using SPSS, GeoDA and ARCGIS. Economic differences tend to increase; economic agglomeration tends to weaken overall; regional economic development is relatively stable; according to the 2010 index of regional economic development level, the county-level administrative units in the radiation zone of Lanxin Railway can be divided into: economically underdeveloped areas, Economically underdeveloped areas, economically more developed areas and economically developed areas. According to the relationship between county-level administrative units and their neighboring units, the administrative units of the county-level radiation belts of Lanxin Railway are classified into diffuse, polarization, The economic subsidence area is located in the southeastern part of the Lanzhou-Xinjiang railway radiation belt. The regional economic development along the Lan-Xin Railway is “ ”Gradual proliferation.
