基于可拓物元的安徽省城市化综合评判研究

Comprehensive Evaluation of Urbanization Level Based on Extension Matter Element Model in Anhui Province

通过科学构建城市化评价指标体系,利用安徽省及16地市2016年统计数据,运用物元模型和主成分分析方法评价其城市化发展水平.结果表明:(1)安徽省城市化总体水平偏低,一半以上的区域处于中等城市化和低城市化水平状态,与普通概念上的人口城市化水平差距较大,城市化发展水平区域差异明显,不同区域城市化影响因素存在一定的差异,且城市化水平发展空间较大,安徽省城市化发展水平与区域经济发展程度具有高度一致性;(2)物元模型与传统评价方法相比,既能得到城市化和单指标评价结果,还能获得单指标水平状态和影响程度等分异信息,适合于区域城市化水平评价.

This paper evaluated the urbanization development level by scientificly establishing the evaluation index system of urbanization,uses matter-element analysis and principal component analysis model based on statistical data in 2016 in Anhui province.The results show that:(1)Regional urbanization overall level is on the low side,more than half of the regions are in the state of moderate urbanization and low urbanization in Anhui Province,this is far from the normal concept of population urbanization.There are obvious regional differences and the more development space in the level of urbanization.At the same time,the urbanization development level is highly consistent with the degree of regional economic development.(2)Compared with the traditional evaluation method,the matter-element model divided urbanization evaluation results into 4 grades in Anhui province.This method can not only get the level of urbanization,but also get the subordinative degree to some urbanization grade,and differentiation information of single index state and influence degree,etc.So this method is more suitable for the evaluation of regional urbanization.
