针对已有湖北省县域经济差异研究多缺乏空间视角的现状,该文采用GIS探索性空间数据分析—地理信息系统及传统统计分析方法,以2003—2013年湖北省县域人均国内生产总值为研究对象,运用标准差、变差系数及空间自相关模型等,从时空视角对湖北省县域经济发展空间演化特征进行分析。结果表明:湖北省县域经济发展绝对差异呈扩大趋势,相对差异有所减小;县域经济发展存在较强的空间自相关性,经济发展水平相似县域趋向于集中分布;武汉市和宜昌市为湖北省县域经济发展核心地区,与周围县市经济水平存在显著空间差异;县域经济发展热点空间格局演化幅度较大,形成以武汉市和宜昌市为核心、层级较为分明的经济发展空间格局;鄂西地区始终为经济发展的冷点区,西部和中东部地区县域经济发展不平衡。
In view of the lack of spatial perspective from the existing studies on county-level economic disparity in Hubei Province, this paper uses GIS exploratory spatial data analysis - geographic information system and traditional statistical analysis methods to study the per-capita GDP of Hubei Province from 2003 to 2013 Object, using standard deviation, coefficient of variation and spatial autocorrelation model to analyze the spatial evolution characteristics of county economy in Hubei Province from the perspective of space-time. The results show that the absolute difference of county economic development in Hubei Province shows an increasing trend with the relative difference decreasing; the county economic development has strong spatial autocorrelation; the county with similar level of economic development tends to be concentrated; Wuhan and Yichang are Hubei In the core area of provincial economic development, there are significant spatial differences with the economic levels of the surrounding counties and cities. The hotspot spatial pattern of county economic development has evolved in a large scale, forming a spatial pattern with distinct levels of economic development centered on Wuhan and Yichang. The region has always been a cold-spot area for economic development, and the economic development in the western and central-eastern regions has been uneven.
