基于R语言的我国城镇居民消费水平研究
Research on the Consumption Level of Urban Residents in China Based on R Language

本文针对我国城镇居民人均可支配收入及消费支出开展研究，选取了国家2020年的统计年鉴数据，利用RStudio软件对数据进行采集、处理与分析，主要开展了描述性分析及线性回归分析。描述性分析得出全国31个省级区域人均可支配收入和人均消费支出的构成、占比与差异性；回归分析构建了可支配收入与消费支出之间的散点图，分析二者之间的数据关系，并利用一元线性回归模型验证二者之间的拟合度。本文创新性地基于R语言分析了我国城镇居民人均可支配收入与人均消费支出的内生动力及相关性程度，并以数据分析结果为依据，全面量化阐述东西部省份之间消费水平的差异及趋势，所采用的技术路线具备延展性并适用于其它时间段，对国家及地区宏观经济研究具有一定的参考价值。
This paper carries out research on the per capita disposable income and consumption expenditure of urban residents in China, selects the national statistical yearbook data of 2020, uses RStudio software to collect, process and analyze the data, and mainly carries out descriptive analysis and linear regression analysis. Descriptive analysis results in the composition, proportion and difference of the per capita disposable income and per capita consumption expenditure of the national 31 provincial regions; the regression analysis constructs the scatter plot between disposable income and consumption expenditure, analyzes the data relationship between the two, and verifies the fit between the two using a one-dimensional linear regression model. This paper innovatively analyzes the endogenous dynamics and degree of correlation between per capita disposable income and per capita consumption expenditures of urban residents in China based on R language, and comprehensively quantifies the differences and trends in the consumption level between eastern and western provinces based on the results of the data analysis, and the technical route adopted has the extensibility and applicability to other time periods, which is of a certain reference value to the national and regional macroeconomic research.
