| Abstract: | With both the ELES model and Bayesian method,the urban resident consumption structure is analyzed based on the related economic series data（consumption and income） since the time of Reform.The posterior mean and median are used as posterior estimation of the model parameters to study the trend of the consumption structure.A suggestion is given to promote the economic growth and consumption expension. |

| Keywords: | consumption structure demand function boundary consumption tendency Bayesian estimation |
