基于聚类分析的我国城镇居民消费结构差异化研究

Research on Chinese Urban Residents' Consumption Structure Differentiation Based on the Cluster Analysis

居民消费结构不仅反映地区居民消费偏好程度以及对居民收入、消费品价格等因素的敏感程度,而且能反映地区居民的生活质量与区域经济发展水平.本文基于聚类分析方法原理,构建类之间最小距离关于分类数的函数关系,然后根据曲线在分类数点的曲线斜率变化特征确定分类数,对2013年我国31个省、直辖市、自治区的城镇居民消费结构差异化特征进行研究.研究结果表明我国城镇居民结构还存在较大差异,将近三分之二属于中西部地区的省份消费水平在全国平均水平以下.

Residents＇ consumption structure reflects not only the preference degree of regional resident consumption as well as the sensitive degree of the residents income and consumer price,but also the residents＇ quality of life and the regional economic development level.This paper,based on the principle of clustering analysis method,builds a function of minimum distance between classes about classification,and then determines the classification number according to the curve slope characteristics that in the classification number to research the consumption structure differentiation characteristics of Chinese urban residents for urban residents of 31 provinces,municipalities and autonomous regions in 2013.Research results show that there are great differences in the structure of urban residents in China,nearly two-thirds of the provinces belong to the Midwest where the consumption level is below the national average level.
