利用空间分析法确定兰新铁路辐射带的辐射范围,以县级行政单元为基本研究单元,综合运用SPSS、GeoDA和ARCGIS分析区域经济差异后发现:在兰新铁路辐射带内,兰州市市辖区、乌鲁木齐市市辖区、嘉峪关市、哈密市、阿拉善左旗的经济发展水平明显比其它地区高,甘肃段内区域经济差异较大,新疆段内区域经济差异较小;区域经济空间集聚特征明显;利用空间计量经济模型分析区域经济差异成因可知,财政收入对经济发展具有明显的负面影响,市场规模、经济结构、工业化、虚拟变量对经济发展具有明显的促进作用,其中虚拟变量与经济发展水平的回归系数最大,说明农村城市化对经济发展的促进作用最大。区域投资水平对经济发展影响不明显。
Using the spatial analysis method to determine the radiation range of the Lanzhou-Xinjiang railway radiation belt, taking the county-level administrative unit as the basic research unit and analyzing the regional economic differences by using SPSS, GeoDA and ARCGIS, it is found that within Lanzhou-Xinjiang railway radiation zone, , Urumqi City, Jiayuguan City, Hami City, Alxa Left Banner’s economic development level was significantly higher than other regions, large differences in regional economy in Gansu Province, Xinjiang region less significant regional economic differences; regional economic agglomeration of the obvious characteristics ; The use of space econometric model analysis of the causes of regional economic differences shows that fiscal revenue has a significant negative impact on economic development, market size, economic structure, industrialization and virtual variables have a significant role in promoting economic development, of which the dummy variables and economic development level The regression coefficient is the largest, indicating that rural urbanization has the greatest effect on economic development. The impact of regional investment on economic development is not obvious.
