Spatial Pattern Evolution and Influencing Factors of County Economy Based on Nighttime Light Remote Sensing in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong
In the context of the state's strong support for the revitalization and development of the Former Sovi-et Area,and in view of unbalanced and inadequate economic development in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong,the TNL index was constructed based on the nighttime lighting data to measure the regional economic development level,and NICH index,standard deviation ellipse,spatial autocorrelation analysis and multi-scale geographical weighted regression analysis were comprehensively used to study and analyze the spatial pattern evolution characteristics and influencing factors of county economy in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong from 2011 to 2020.The results are as follows.(1)The whole regional county economy has the spatial differentiation characteristics of high in the south and low in the north,and the polarization phenomenon of economic growth is obvious.(2)The whole regional county economic center of gravity moves in a trend of northeast-northwest-southwest,and the economic development of western and northern regions is faster than that of eastern and southern regions.(3)The overall spatial correlation of the whole region's economy is weak,and there are areas of"contiguous poverty".The economic hotspots are mainly concentrated in the southeast of the region.(4)The economic strength,industrial structure,productivity level and road conditions play significant positive roles in promo-ting regional economic development.This study will provide decision support for promoting the economic revitalization and coordinated development of the Former Central Soviet Area of Jiangxi,Fujian and Guangdong.
