宁夏县域经济发展空间分异研究

Study on Spatial Variation of County Economy Development in Ningxia

基于地理信息系统技术,运用因子分析与探索性空间数据分析法(ESDA)对宁夏县域经济发展的空间分异进行研究.结果表明,宁夏各县市经济发展不平衡,经济发达区位于宁夏北部沿黄地带,落后区位于宁夏南部山区;北部重要节点城市对宁夏整体经济发展水平带动作用不强;宁夏县域经济发展存在明显的空间聚集分布特征;存在局部极化现象,即经济发展水平较高的地区,其周边地区经济发展水平较低,对周边地区经济发展的扩散效应较弱.

Basing on geographical information system technique,this article analyzes the spatial variation of Ningxia＇s county economy development with factorial analysis and exploratory spatial data analytical method（ESDA）.The result shows that the economic development in individual Ningxia counties is uneven that the economic developed area is in north Ningxia＇s area along the Yellow River,backward area lies in southern mountain area of Ningxia,and the important node city in north Ningxia has weak leading role on Ningxia＇s macroeconomic development;the development of Ningxia＇s county economy has distinct spatial aggregated distribution characteristic;there is the partial polarization phenomenon,that is,faster economic development area has lower development of surrounding area,the diffusing effect of which on the surrounding area is also weaker.
