Abstract: Based on the eight indicators of the residents’ consumption type and consumption statistics in Sichuan province from 1998 to 2011, the entropy, equilibrium degree and dominance are calculated and analyzed. Results show that the information entropy of the residents’ consumption structure has increased from 1.355 to 1.812, showing an overall wave rising trend, the consumption structure becoming perplexed; Equilibrium degree has risen from 0.652 to 0.652, indicating the proportional differences between the consumptions are becoming smaller and smaller; Dominance has declined from 0.348 to 0.129, reflecting the degree of residents’ consumption which gives priority to food consumption projects has undergone changes. Therefore, the corresponding countermeasures and suggestions are put forward, which is aimed at promoting consumption and optimizing the consumption structure.
