摘要
用主成分分析法、标准差、变异系数、对数偏差均值指数等对甘肃省近20年来的区域经济差异进行了分析研究,得出以下结论:①从区域经济发展水平差异的空间格局上讲,定西、平凉、庆阳3市经济处于上升趋势,武威、临夏、甘南3州市经济处于下降趋势,其他地区处于基本稳定状态,而且经济水平基本呈西北高、东南低,并形成了以兰州和嘉峪关为中心的经济圈雏形;②从总体变化趋势上看,甘肃省的区域经济绝对差异在拉大,且速度呈阶梯式变化;③区域经济差异在高—低城镇化方向上变化复杂;④区域经济差异在河西—河东方向上主要表现为河西—河东内部的差异.
Based on approaches of principal components analysis and standard deviation,coefficient of variance,the mean logarithmic deviation,this paper carries out an empirical analysis on regional disparity of the economic development levels of Gansu Province in recent 20 years.The major findings include：① in space pattern,the levels of regional economic development disparities vary greatly.Pingliang,Qingyang and Dingxi are on the rise,Wuwei,Linxia and Gannan are declining,while others are basically stable.The levels of economic take appearance of higher in the north-west and lower in the south-east,and the economic circle has been taking its shape,whose centre is Lanzhou and Jiayuguan.② As a whole,the absolute disparities in Gansu Province are widened with staged speed,the relative disparities fluctuate largely.③ In the high-low urbanization dimensions,the regional economic disparities change complexly.④ In western-eastern of Yellow River dimensions,the main factor of regional economic disparities is the inter regional disparity.
