2000年以来甘肃省经济发展的空间格局演化

The evolution of spatial pattern of economic development in Gansu Province since 2000

本文以甘肃省86个县级行政单元为研究对象,通过空间自相关分析揭示其经济发展机制主要为极化效应,集聚特征明显,对空间依赖性较强;运用变差函数法分析经济发展空间关联效应并对其演化影响因素进行总结。结果表明:受制于城镇经济结构,15年来甘肃省经济发展缓慢;甘肃省经济发展空间格局具有显著集聚特征,两极分化严重,东北-西南方向和南-北方向上经济发展差异较大;陇中是甘肃省经济发展水平最高的地区,河西走廊地区经济发展水平有所降低,东南部的庆阳-平凉地区经济发展潜力巨大。

This study,based on 86 county-level administrative units in Gansu as the research object,used GIS method and Spatial Autocorrelation Analysis.It showed that the main economic developing mechanism is polarization effect,and there were obvious agglomeration characteristics.Then it analyzes the economic spatial association by using Variation Function.Finally,the evolution of the impact of factors is summarized.The study found that the impact of China’s West Development Strategy in Gansu is limited on economic development.The economic development of Gansu was slow in 15 years restricted by the factors of urban economic structure.The spatial pattern of economic development has a significant agglomeration characteristic.The economic development has a large difference in north-south and northeast-southwest directions.The central region is the highest level of economic development in Gansu.The level of economic development in the Hexi Corridor has been reduced,but it is growing fast in the southeast.
