本文选用能体现城镇居民消费结构的8个统计指标,运用因子分析和聚类分析的方法对安徽省人均和各地区的城镇居民消费结构进行区域型差异分析和研究。首先根据城镇居民的人均消费状况,得到因子模型,并分析其变动趋势,提出优化安徽省城镇居民消费结构的建议。其次,选择2012年安徽省16个市的城镇居民消费作为原始数据,进行主成分分析;然后选择三个主因子,采用回归算法求出综合因子得分函数。最后,计算各地区的综合因子值进行聚类分析,探讨安徽省各区域之间城镇居民消费结构的差异。
This paper selects eight statistical indicators that can reflect the consumption structure of urban residents, and uses factor analysis and cluster analysis to analyze and study the regional differences of per capita consumption of urban residents and urban residents in various regions in Anhui Province. First, according to the per capita consumption of urban residents, a factor model is obtained, and the trend of change is analyzed. Proposals are made to optimize the consumption structure of urban residents in Anhui Province. Secondly, the urban residents’ consumption in 16 cities of Anhui Province in 2012 was selected as the primary data to conduct the principal component analysis. Then, the three main factors were selected and the comprehensive factor score function was calculated by the regression algorithm. Finally, we calculate the value of the comprehensive factors in each region and do the cluster analysis to explore the differences of urban residents’ consumption structure in different regions of Anhui Province.
