摘要
运用数理统计分析、主成分分析和探索性空间数据分析方法,研究了黄河流域306个县域单元2004—2019年的经济发展时空演变过程及其影响因素。结果表明:①流域内县域经济变异曲线的绝对差异与相对差异均呈“逐步扩大—波动缩小”的演变趋势;②县域经济空间发展水平不均衡,呈东高西低的分布特征;③县域经济存在明显的空间正相关关系,热点区主要集聚在流域北部的鄂托克旗和东部的新密市等县市,而流域西部则多为冷点和次冷点区域,空间分布重心由东北向西南偏移趋势显著;④自然地理条件、自然资源储存丰度、经济发展机遇和政策制度导向是影响县域经济时空演变的重要因素。
Using mathematical statistical analysis,principal component analysis and exploratory spatial data analysis,we studied the spatio-tem-poral evolution of economic development and its influencing factors of 306 county units in the Yellow River Basin from 2004 to 2019.The re-sults are as follows①the absolute and relative differences of county economic variation curves in the basin show an evolutionary trend of“grad-ually expanding and fluctuation decreasing”.②The spatial development level of county economy is uneven,showing the distribution characteris-tics of high in the east and low in the west.③There is an obvious spatial positive correlation between county economy.The hot spots mainly con-centrate in Etog Flag in the north of basin and Xinmi City in the east of basin,while the cold spots and sub-cold spots are mostly in the west of ba-sin.The gravity center of spatial distribution of county economy shifts significantly from northeast to southwest.④Physical geographical condi-tions,abundance of natural resources,economic development opportunities and policy and institutional guidance are important influencing fac-tors for the spatio-temporal evolution of county economy.
