基于地统计分析的遵义市县域经济空间差异研究

AStudy on the Spatial Differences of County Economy in Zunyi City Based on Geostatistics Analysis

文章以遵义市14个县级地域单元为研究对象,选取人均GDP作为经济发展水平的衡量指标,在ArcGIS、GeoDa、SPSS等软件的支持下对遵义市2007-2021年县域经济发展水平进行可视化表达、数理统计分析和空间计量分析,从时间和空间二维角度研究遵义市县域经济格局演变和影响因素。研究结果表明:(1)遵义市县域经济绝对差异总体呈现扩大趋势,相对差异呈现波动下降趋势;(2)经济发达地区主要集中在市区(红花岗区、汇川区、播州区)和仁怀市,呈现南高北低、西高东低的空间格局;(3)遵义市县域经济空间差异呈现缩小趋势,由“较为不平衡”向“趋于平衡”演变;(4)生产力因素和资本因素是影响遵义市县域经济空间差异的主要因素。

Taking 14 county-level regional units in Zunyi City as the research objects,this paper selects per capita GDP as the measure-ment index of economic development level,and with the support of ArcGIS,GeoDa,SPSS and other software,it conducts visual ex-pression,mathematical statistics analysis and spatial econometric analysis of the county economic development level in Zunyi City from 2007 to 2021,and studies the evolution of the county economic pattern and influencing factors in Zunyi City from the perspective of time and space.The research results indicate that:(1)The absolute difference in the county economy of Zunyi City shows an overall trend of expansion,while the relative difference shows a fluctuating downward trend;(2)The economically developed areas are mainly con-centrated in urban areas(Honghuagang District,Huichuan District,Bozhou District)and Renhuai City,presenting a spatial pattern of high in the south and lowin the north,and high in the west and lowin the east;(3)The spatial differences in the county economy of Zunyi City are showing a decreasing trend,evolving from“relatively unbalanced”to“approaching equilibrium”;(4)Productivity and capital factors are the main factors that affect the spatial differences in the county economy of Zunyi City.
