多元统计分析在新疆城镇居民消费结构中的应用

Application of Multivariate Statistical Analysis in the Consumption Structure of Urban Residents in Xinjiang

为了研究新疆各地区城镇居民消费结构变动情况,本文选取了2015年新疆20个地区的城镇居民在八大消费指标中的最新数据,基于spss采用多元统计方法中的因子分析法、聚类分析法对新疆20个地区城镇居民的消费结构变动因子和消费支出情况进行描述性统计分析,并利用R软件画出各个地区的消费结构星形图,研究发现,近年来新疆各地区城镇居民整体消费水平逐渐提高,居民食品支出占总支出的比重逐步减小,表明老百姓生活越来越好,交通与通讯、医疗保健和居住消费比重逐年上升,表明老百姓消费层次不断提升,消费支出不断呈现多元化态势,然后在将新疆20个地区分为四类的基础上,分析比较各类地区消费结构的差异及其成因,从总体上掌握了新疆各地区消费结构的特点,为新疆制定优化的消费政策提供一定的决策依据,最后就如何促进新疆城镇居民的均衡合理消费,以此拉动新疆经济发展提出相应的建议。

In order to study the changes in the consumption structure of urban residents in various regions of Xinjiang, this paper selects the latest data of urban residents in 20 regions in Xinjiang in 2015, based on the factor analysis and cluster analysis of multivariate statistical methods based on SPSS. The law makes a descriptive statistical analysis of the consumption structure change factors and consumption expenditures of urban residents in 20 regions of Xinjiang, and uses R software to draw the star map of consumption structure in each region. The study found that in recent years, the overall consumption level of urban residents in various regions of Xinjiang has gradually increased, and the proportion of household food expenditure to total expenditure has gradually decreased, indicating that the lives of ordinary people are getting better and better, and the proportion of transportation and communication, medical care and housing consumption is increasing year by year, indicating The consumption level of ordinary people has been continuously improved, and consumer spending has been continuously diversified. Then, based on the classification of 20 regions in Xinjiang, the differences in consumption structure in various regions and their causes have been analyzed and compared, and the regions in Xinjiang have been mastered in general. The characteristics of the consumption structure provide a certain decision-making basis for Xinjiang to formulate optimized consumption policies. Finally, it puts forward corresponding suggestions on how to promote the balanced and reasonable consumption of Xinjiang urban residents, so as to promote the economic development of Xinjiang.
