Mao Rui and Xu Jianwei (2014) analyzed the household population survey data of urban residents and found that there were significant differences in the consumption level of residents of different ages. The conclusion is that age is the key factor to determine the consumption level of urban residents. Sun Wei and Yang Bocheng (2015) conducted nonlinear econometric analysis based on threshold model. The research shows that the consumption level of urban residents is different because of the obvious difference of income group of urban residents, and the development stage of various consumer markets is also different because of the difference of income. They believe that the change of residents' income level is the reason for the change of consumption level from survival consumption to entertainment consumption. Therefore, this paper uses Eviews to analyze and study the influence of urban consumption level from the following five aspects: the actual per capita disposable income of urban residents in Tianjin, the actual per capita index of urban residents in Tianjin GDP, registered unemployment rate of urban residents in Tianjin, investment in fixed assets in Tianjin.
