【摘要】：随着我国经济不断发展,居民收入和消费逐渐变为热点的话题。越来越多的研究学者应用各种方法对收入与消费进行深入分析和研究,创立了很多理论和模型,对居民收入和消费提供了理论指导和研究方法。本文对我国居民收入和消费支出情况进行了统计分析,指出我国居民在收入和消费方面的问题,并针对问题给出合理的建议。首先,对我国各省市地区的收入与支出进行描述统计分析,直观的给出我国居民收入与消费变动情况;其次,应用聚类分析对我国各省市的收入与消费情况进行分类,给出不同省市所在类别,再应用典型相关分析对居民收入来源和支出方面进行分析,探讨收入与消费的相关度。再次,应用回归分析的方法,对我国居民收入与消费方面进行拟合分析,根据回归检验结果,检验模型是否符合多元线性回归的基本假定。本文主要针对具有多重共线性的情况下的模型选择,应用有偏估计中的主成分回归、岭回归和变量选择中的逐步回归、绝对约束估计、弹性约束估计方法进行分析,比较各个模型的优缺点,选出最好的模型,并对参数进行经济意义上的阐释。最后,根据分析的结果,对我国居民收入和消费情况,给出合理性的建议。
[Abstract]:With the development of our economy, income and consumption have become a hot topic. More and more researchers apply various methods to analyze and study income and consumption, and many theories and models have been established, which provide theoretical guidance and research methods for residents' income and consumption. This paper makes a statistical analysis on the income and consumption expenditure of Chinese residents, points out the problems in income and consumption of Chinese residents, and puts forward some reasonable suggestions for the problems. First of all, the income and expenditure of provinces and cities in China are described and analyzed, and the changes of income and consumption of Chinese residents are intuitively given. Secondly, the income and consumption of provinces and cities in China are classified by cluster analysis. In this paper, different provinces and cities are given, then the source of income and expenditure of residents are analyzed by canonical correlation analysis, and the correlation between income and consumption is discussed. Thirdly, the regression analysis method is used to analyze the income and consumption of Chinese residents. According to the results of regression test, the model is proved to be consistent with the basic assumption of multivariate linear regression. In this paper, we apply the principal component regression in biased estimation, ridge regression and stepwise regression in variable selection, absolute constraint estimation and elastic constraint estimation to model selection with multiple collinearity. Compare the advantages and disadvantages of each model, select the best model, and explain the parameters in economic sense. Finally, according to the results of the analysis, reasonable suggestions are given to the income and consumption of Chinese residents.
