长江经济带区域经济差异与空间格局分析

Analysis on Regional Economic Difference and Spatial Pattern of YREZ

文章基于2006—2015年长江经济带126个主要地区的经济统计数据,采用泰尔系数与GIS-ESDA探索性空间分析方法,对长江经济带区域经济差异与空间格局进行分析。结果表明,长江经济带经济发展水平总体差异明显,但呈现减弱趋势,各城市间差异大于城市群际之间差异;经济发展水平较高的地区主要集中在长三角州城市群,正相关集聚效应显著;中游城市群地区中心城市与外围城市经济联系度不强;西部成渝城市群地区、滇中、滇南城市群区缺乏高水平地区,低低水平集聚关系较为显著;长江经济带经济空间组织特征呈现多核心与单核心边缘结构特征。

Based on the economic statistical data of 126 major regions on the Yangtze River Economic Zone （YREZ） from 2006 to 2015, this paper adopts Theil index and GIS exploratory spalial data analysis （ESDA） to analyze the regional economic difference and spatial pattern of the YREZ. The result is shown as follows： the economic development levels are totally obviously dif- ferenl on the YREZ, but the difference gradually weakens; the gap between each city is bigger than that between urban agglomeralions; the high-level economic development areas concentrate in the urban agglomerations of the Yangze River Delta and its positive correlation agglomeration effect is remarkable; there is weak economic connection between the central cities of the urban ag- glomeration and peripheral cities in the middle reaches; high-level developing areas are scarce in the western Chengdu-Chongq- ing urban agglomeration area, the urban agglomeration area in the central and southern region of Yunnan Province, hence obvious low-low level concentration; the spatial organization of the YREZ are characterized by ＂multi core and single core＂ limbic strncture.
