Based on the principal component analysis method of multivariate statistical analysis, this paper constructs various models for the income sources of urban households in China by means of MATLAB and SPSS. The status quo of the income sources of urban households in China is objectively analyzed by adopting the factor analysis to categorize the 31 provinces [1], municipalities and autonomous regions in China by income sources. Moreover, the author analyzes the income sources of and correlations between urban residents in different regions of China in 2015 and draws some useful conclusions. Some rational suggestions are presented to further improve the income of residents.
