辽宁省城市规模结构演变分析

Analysis on the Evolution of Urban Scale Structure in Liaoning Province

采用2001~2012年的非农人口数据,运用城市首位度、城市规模分布的基尼系数等理论与方法对辽宁省城市规模演变展开了计量分析,更深层地探讨了辽宁省城市规模空间演化的特征。结果表明:辽宁省城市规模等级结构呈现出阶梯式的演替特征;辽宁省城市规模成长体现出区域差异性、群带集聚性等特征;就其发展规模来看,辽宁省的发展趋势呈现出较强的增长态势;位序规模比较大的城市,其带动能力强大,在发展大城市的时候适度带动小城市的快速发展,小城市在依托大城市基础上,利用本身资源和条件,实现质的飞跃。辽宁省的空间发展总体呈现合理均匀的布局,空间极化现象比较常见。

Based on the data of non--agricultural population from 2001 to 2012, this paper used the theory and method of Gini coefficient of urban first degree and urban scale distribution to analyze the scale of urban scale in Liaoning Province. It further discussed the spatial evolution of urban scale in Liaoning Province feature. The results showed that： the size of the hierarchical structure of Liaoning Province city showsa step-by-step succession; The growth of urban scale in Liaoning Province is characterized by regional differences and group agglomeration; In terms of its scale of development, Liaoning Province shows strong growth situation; The city with relatively large size has strong ability to drive. It is necessary to lead to the rapid development of moderately small cities when developing large cities. Because small cities rely on large city, using their own resources and conditions can achieve a qualitative leap. The overall spatial development of Liaoningpresented a reasonable uniform layout with common spatial polarization phenomenon.
