辽中城市群县域综合发展水平差异的时空特征分析

经济发展规模水平、社会发展水平及产业结构水平是影响辽中城市群发展差异的主要因子,2000~2005年经济发展规模水平因子由第二主因子上升为第一主因子;以指数方法测度,县域综合发展水平差距要小于经济发展规模水平、社会发展水平和产业结构水平的差距;城市群县域综合发展水平呈双核结构,具有南北分异、东西分异、高值西南集聚、低值东北集中的空间正相关性特点,呈现南北分异的空间变动特征,使各县域空间正相关性增强;在市域范围内,基本上距离市域核心越远,县域综合发展水平下降越多;大多数县域协调度下降,城市群整体协调状况不理想。

Spatio-temperal Characteristics of sparity of Counties Comprehensive Development Level in Central Liaoning Urban Agglomeration

Based on factor analysis method and ARCVIEW technology,taking central Liaoning Urban Agglomeration as an example,this paper makes a comprehensive assessment on the socio-economic development at county level,and reveals the actual characteristics and evolving characteristics of spatial disparity of urban agglomeration from 2000 to 2005.The results are as follows.Firstly,factors that mainly influence the interior development differentiation of Central Liaoning Urban Agglomeration are economic scale,social development,and industrial structure.Their weighs are different,and the economic scale had changed from second factor to first one from 2000 to 2005,which indicates that these three factors are not in a harmonious condition and the economy scale had been the main factor to prompt the comprehensive development of the urban agglomeration.Secondly,at county level,estimated by indexes,the absolute differentiation of comprehensive development level is smaller than that of economic scale,social development and industrial structure.Thirdly,Shenyang City and Anshan City have been both centers of Central Liaoning Urban Agglomeration,and north-south disparity and east-west disparity are forming.Fourthly,variability of comprehensive development level of county is severe,and it shows north-south disparity. By and large,comprehensive development level of county decreases step by step from a central county to a marginal county in the administrative region of a city.Finally,most counties were not in the harmonious development condition,and the harmonious degrees of most counties had descended from 2000 to 2005.
