城市化水平的度量研究

On Measuring the Urbanization Level

城市化水平是城市化研究中一个很重要的概念和度量指标,长期以来,人们习惯用城市人口比重占总人口比重来测度城市化水平,这种方法在有些资料不够健全的地区是可行的,但它同样存在着诸多弊端和局限性,如城市人口难以包容城市化的全部内涵,难以反映城市化"质"的问题等。从经济、人口、基础设施和生活方式入手,用综合指标法构建城市化水平评价指标体系;运用主成分分析方法对全国31个省市作了度量及评价分析。

Urbanization level is an important concept and measure index in urbanization study. Researchers have been used to measuring urbanization level by the percentage of urban population occupying the total population for a long time. It is a fairly feasible method and also the most scientific one particularly in some areas where necessary data are incomplete. On the other hand, this method has a few limitations, because the only index of city population cant cover all content of urbanization, nor represent the quality of the urbanization. Through building the appraisal index system based on economy, population, infrastructure and life styles, this paper looks into the urbanization levels of the 31 provinces in China with the methods of main factor analysis and comprehensive index.
