摘　　要：本文运用因子分析法研究2019年我国31个省市地区城镇居民家庭人均年消费支出数据来探讨我国城镇居民的消费水平和消费结构。借助R统计软件,输出相关系数矩阵,碎石图,旋转前后载荷矩阵,因子得分图以及各地区综合得分与排名,最后得出结论:中国不同地区城镇居民消费结构显著差异,消费支出发展失衡,水平各异。除经济快速持续发展的上海、北京、浙江以外,绝大多数地区消费水平仍需努力提升,调整相应的消费结构,促进经济焕发生机。This article discusses consumption structure and the level of consumption of urban residents by studying the per capita annual consumption expenditure data of urban households from 2019 with factor analysis method about 31 regions in China. With the help of R statistical software, the correlation coefficient matrix, gravel graph, the load matrix before and after the rotation, factor score map and the comprehensive scores and rankings of each region are given. Finally, we can draw a conclusion: the consumption structure of urban residents in different regions of China is significantly different;also, the development of consumption expenditure is unbalanced. Except for Shanghai, Beijing, and Zhejiang, where the economy is developing rapidly and sustainably, most regions still need to work hard to improve their consumption levels, adjust the corresponding consumption structure, and promote economic revitalization.
