黄河流域县域经济密度测算及空间分异研究
A study on estimates and spatial differentiation of economic density at county level in Yellow River Basin
摘要
Abstract
The county economy is the basic unit of the national economy,and the scientific evaluation of the spatial differentiation,influencing factors and formation mechanism of the county economy can provide a scientific basis for the evaluating regional economic and making regional development policies.This paper takes the Yellow River Basin of 504 counties as the study area.The entropy grey correlation analysis,the Jenks classification and Kernel analysis was used to construct the evaluation index system and comprehensive evaluation model of economic density based on per capita income and per area income.Then the characteristics of spatial differentiation,influencing factors of the Yellow River Basin counties has been studied from two dimensions including spatial distribution characteristics and spatial agglomeration statusin 2000 and 2014.The results show that,first,the overall economic spatial density pattern was mainly affected by the per capital income and per area income just has strengthen or weaken influence on the intensity differentiation.Second,there is a big difference of the regional economic density between eastem and mid-west parts of the study area.With the high economic density in the eastern region,two agglomeration regions were formed.One is around Zhengzhou and Jinan in the eastern region with high-level,the other is around Xi'an in the mid-east region with relatively lower-level compare to the first one.In the contrary,the western and central parts showed only a few weak agglomerations with the lowest-level.Third,the spatial differentiation is changingin the mid-west region.More specifically,the overall economic density level in Henan and Inner Mongolia is higher than other provinces.The agglomeration center and axis are mainly located in middle of Inner Mongolia and middle of Henan,the south of Shaanxi,the middle of Shanxi.关键词
