摘　　要：在国家大力支持原苏区振兴发展背景下,针对赣闽粤原中央苏区县域经济发展不平衡、不充分的现状,研究基于夜间灯光数据构建TNL指数衡量地区经济发展水平,并综合运用NICH指数、标准差椭圆、空间自相关分析以及多尺度地理加权回归分析等方法,对赣闽粤原中央苏区2011—2020年的县域经济空间格局演变特征及影响因素进行研究分析。结果表明:(1)全区县域经济存在南高北低的空间分异特征,经济增长的极化现象明显;(2)全区县域经济重心移动趋势为东北—西北—西南,西、北部经济发展快于东、南部地区;(3)全区经济总体空间关联性较弱,存在“连片贫困”地区,经济热点区主要聚集分布在区域东南部;(4)经济实力、产业结构、市场购买力和道路条件对地区经济发展起到了显著的正向促进作用。本研究将为推动赣闽粤原中央苏区经济振兴、协调发展提供决策支持。In the context of the state's strong support for the revitalization and development of the Former Soviet 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 promoting 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.
