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。
The marginal area of the province is a new area in the study of the spatial differentiation of regional economy. Based on the county (district) scale, this paper selects 14 indexes to measure the economic level. By using the method of factor analysis and ESDA-GIS, Economic Zone Economic Spatial Differentiation. The results show that: (1) the number is unevenly distributed, the tendencies are stronger and the weaker are increasingly marginalized; (2) the spatial distribution shows the trend of east-west increasing and south-north decreasing; (3) the global Moran’s I index The score is 0.3215, which indicates that the economic development in districts and counties has the characteristics of “convergence club”. ④ The spatial distribution of the four types of spatial correlation types of diffuse, polarized, “collapsed” and “contagious” Center - Perimeter grade features, but not significant. Further study found that there are significant differences in the spatial concentration of the four factors of economic input, economic efficiency, human capital and economic structure.
