摘要
基于福建省县域统计经济数据和校准预处理后的NPP-VIIRS夜间灯光数据,揭示县域统计经济数据与夜间灯光数据的关联,在此基础上探讨县域经济发展时空演化特征。结果表明:(1)夜间灯光总量与地区生产总值(GDP)高度相关,县域夜间灯光总量集中分布在东南沿海地区,沿海县(市)单位面积夜间灯光总量高于内陆县(市),夜间灯光总量空间分布呈现高度不均衡性;(2)县域GDP全局自相关指数以及夜间灯光全局自相关指数呈显著正相关水平,县域夜间灯光数据空间集聚水平低于县域GDP空间集聚水平,夜间灯光数据高高聚类区域相比县域GDP高高聚类区域呈扩张趋势;(3)夜间灯光数据和经济指数热点区域均分布在东南部沿海地区,冷点区域主要分布在三明和南平等地区部分县(市),夜间灯光数据和统计经济数据冷热点之间存在一致性。为缩小区域发展差异,需加大经济政策扶持,促进区域经济交流,带动经济同步增长,研究结果可为县域经济发展政策制定提供参考借鉴。
Based on the county statistical economic data and calibrated pre-processed NPP-VIIRS nighttime light data in Fujian Province,the association between county statistical economic data and nighttime light data is revealed,and the spatial and temporal evolution characteristics of county economic development are explored on this basis.The research results show that:(1) The total amount of nighttime lights is highly correlated with gross regional product,the total amount of nighttime lights in the county is concentrated in the southeast coastal area,the total amount of nighttime lights per unit area in coastal counties and cities is higher than that in inland counties and cities,and the spatial distribution of the total amount of nighttime lights shows a high degree of unevenness;(2) The global autocorrelation coefficient of county GDP and the global autocorrelation coefficient of nighttime lights show a significant positive correlation level,and the spatial concentration level of nighttime lights data in the county is lower than that of inland counties.Lighting data spatial clustering level is lower than the county GDP spatial clustering level,nighttime lighting data high-high clustering area than the county GDP high-high clustering area is an expansion trend;(3) Nighttime lighting data and economic index hot spot areas are distributed in the southeast coastal areas,cold spot areas are mainly distributed in Sanming and Nanping and other areas of some counties and cities,nighttime lighting data and statistical economic data between cold and hot spots there is consistency.In order to reduce regional development differences,it is necessary to increase economic policy support,promote regional economic exchanges and drive simultaneous economic growth,and the research results can provide reference for the formulation of county economic development policies.
