甘肃省区域经济发展差异时空演变分析

Analysis on the Spatio-temporal Evolution of Regional Economic Development Difference in Gansu Province

科学研判区域经济发展差异,是促进区域经济协调发展,推动西部大开发形成新格局的基础。通过对甘肃省14个市(州)2009—2018年经济发展综合水平进行测度并结合空间自相关模型,以揭示甘肃省区域经济发展差异的时空演变特征。结果表明:2009—2018年甘肃14个市(州)经济综合发展水平大幅提高且增速较快,西北高、东南低的地理分布格局显著,地域差异明显,存在"强者恒强,弱者恒弱"的局面;甘肃区域经济发展存在较强的空间正相关性,形成了以酒泉、嘉峪关为中心的高水平集聚区和以临夏、甘南等为中心的低水平聚集区,且"低—低"集聚的显著性更强。

Scientific research and judgment of regional economic development differences was the basis for promoting the coordinated de velopment of regional economies and promoting the formation of a new pattern in the development of the western region.By measuring the com prehensive level of economic development of 14 cities(prefectures)in Gansu Province from 2009 to 2018,combined with the spatial autocorre lation model,the characteristics of the temporal and spatial evolution of regional economic development differences in Gansu Province were re vealed.The results showed that from 2009 to 2018,the comprehensive economic development level of Gansu′s cities(prefectures)increased sig nificantly and the growth rate was rapid.The geographical distribution pattern of high in northwest and low in southeast was significant,but the geographical difference was obvious.There was"the strong always strong,the weak always weak"situation;there was trong positive spatial cor relation in regional economic development in Gansu Province,forming high-level agglomeration areas centered on Jiuquan and Jiayuguan and low-level agglomeration areas centered on Linxia,Gannan,etc.,and the significance of"low-low"agglomeration stronger.
