【摘要】：以城乡收入比为测度指标,采用变异系数、泰尔指数、莫兰指数、空间分类、探索性空间数据分析等方法,分析2000年以来长江经济带县域城乡收入差距的空间格局演变及其影响因素。结果显示:12000—2014年变异系数、泰尔指数不断下降,表明长江经济带县域城乡收入差距呈现日趋减小的趋势。2从空间分类格局看,极高、高、较高城乡收入差距区主要分布在西部并形成大范围高值集中区,近期三者的数量大幅减少但依然占据主导;极低、低、较低城乡收入差距区主要分布在中东部地区,在长三角、主要城市群以及经济发达区形成连绵分布区;较高、高城乡收入差距区在中部、东部基本上变化为中等、较低城乡收入差距区,近期这两个类型区几乎消失。3从空间关联格局看,HH区和LL区在空间上集聚格局明显。显著HH区主要在川西、滇西以及滇南形成连绵分布区,近期集聚态势进一步增强;显著LL区在中部、东部的分布范围在不同年份虽有变化但近期集聚效应明显增加,近期显著LL区明显集中在两个区域:一个以武汉城市圈、长株潭城市群为主,另一个是在长三角地区。4影响空间格局的主要因素为:优越的区位条件依然发挥重要作用,农业现代化进程起正向促进作用,经济发展水平起决定性支撑作用,工业化、城镇化发挥重要的推动作用,信息化起一定的"阻碍"作用,战略政策的支持起宏观引领作用。
[Abstract]:Taking urban-rural income ratio as the measure index, using the methods of coefficient of variation, Thiel index, Moran index, spatial classification, exploratory spatial data analysis, etc. This paper analyzes the evolution of the spatial pattern of urban-rural income gap in the Yangtze River economic belt since 2000 and its influencing factors. The results show that the coefficient of variation between 2000 and 2014 and the Thiel index are decreasing, indicating that the income gap between urban and rural areas in the Yangtze River economic belt is decreasing day by day .2 from the perspective of spatial classification pattern, it is extremely high. The higher urban-rural income gap areas are mainly distributed in the west and form a large range of high-value concentration areas. In the near future, the number of the three areas has significantly decreased but still dominates; very low, the lower urban-rural income gap areas are mainly distributed in the central and eastern regions, in the Yangtze River Delta, The main urban agglomeration and the economically developed regions form continuous distribution areas, the high urban-rural income gap areas are in the middle, the eastern areas basically change to the middle, and the lower urban-rural income gap areas, Recently, these two types of regions almost disappeared. 3 from the spatial correlation pattern, the HH region and the LL region in the spatial agglomeration pattern is obvious. The significant HH area mainly forms continuous distribution area in western Sichuan, western Yunnan and southern Yunnan, and the agglomeration trend is further strengthened in recent years, and the distribution range of significant LL in the middle of the region has changed in different years, but the recent agglomeration effect has obviously increased. In recent years, the significant LL area is obviously concentrated in two regions: one is Wuhan City Circle, Changsha-Zhuzhou-Xiangtan Urban agglomeration, the other is the main factor that affects the spatial pattern in the Yangtze River Delta: the advantageous location conditions still play an important role. The process of agricultural modernization plays a positive role, the level of economic development plays a decisive supporting role, industrialization and urbanization play an important role in promoting, informatization plays a certain "hindrance" role, and the support of strategic policies plays a leading role in macro.
