| 摘 要： | 省际边缘区是区域经济空间分异研究中的一个新领域, 本文基于县(区)尺度, 选取衡量经济水平的14 个指标, 运用因子分析和ESDA-GIS相结合的方法揭示呼包鄂榆经济区的经济空间分异。分析结果表明:①数量上呈非均衡发展格局, 趋于强者日趋极化, 弱者日趋边缘化;②空间分布上呈现东-西递增, 南-北递减的分异趋势;③全局Moran’s I指数得分为0.3215, 表明区县经济发展有“趋同俱乐部”特征;④扩散型、极化型、“塌陷”型和“传染”型4 类空间关联类型的空间分布呈现一定的中心-外围式等级特征, 但并不显著。进一步研究发现, 经济投入、经济效率、人力资本和经济结构4因子的空间集中程度差异显著。 |

| Abstract: | Provincial border-regions are a new research field of economic divergence.This paper used counties as the basic study unit and analyzed the spatial differences of 14 economic indexes by using factor analysis methods and ESDA-GIS to reveal the spatial characteristics of economic differences in Hohhot-Baotou-Ordos-Yulin Economic Zone.The following conclusions can be drawn as follows.(1) A non-balanced development pattern of quantity has been presented,which indicates that the strong ones take the trend of polarization,and the weak ones become weaker.(2) The regional spatial structure presents that the county-level economic power increases from east to west and decreases from south to north.(3) County-level economic strength scores of Global Moran’s I is 0.3215,presenting a strong characteristic of"convergence clubs".(4) Diffuse pattern,polarization pattern,"sinking"pattern and"infection"pattern present a core-periphery sphere structure;but it is not an obvious one.It is found that four factors including economic investment,economic benefits,human resources and economic structure are quite distinct from each other in terms of spatial concentration. |
