兰新铁路辐射带区域经济差异研究

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。

Economic disparities in radiation belt of Lan-Xin railway

This research intends to discuss economic development disparities by taking administrative county units in the radiation range as research objects.We got the accurate radiation range through spatial analysis of GIS.Based on the per Regional Gross Product and other relative economic index in Lan-Xin railway radiation belt,the general score of regional economic level were calculated by SPSS,and the time-space disparities of regional economic level in Lan-Xin railway radiation belt were analyzed by means of GIS spatial analysis provided by ARCGIS and GeoDA.Based on study on evolution of economic development disparities,it was concluded that the economic development disparities expand largely.The economic agglomeration resistance takes on reducing tendency.Regional economic development is relatively stationary.According to the general score of region economic level,the administrative county units in Lan-Xin railway radiation belt can be divided into four types: economic developed region,the comparatively developed area,the undeveloped region and under-development area.According to the relationship between the administrative county units and the neighboring units,the administrative county units in Lan-Xin railway radiation belt can be divided into four types: the diffuse pattern,polarization pattern,'sinking' pattern and 'infection' pattern.Lanzhou city and Urumqi city lie in the hot zone,economic collapse area mainly distributes in the southeast part of the Lan-Xin railway radiation belt.Regional economic development level along Lan-Xin railway takes on pole-axles spreading.
