Model and Analysis on the Relation between Income and Entertainment Consumption
Abstract:By methods of questionnaire survey, regression analysis, mathematical modeling and analysis, we proceeded an in-depth study on the quantitative relationship between Changsha inhabitants' income and the entertainment consumption. The obtained main results are as follows: (1) Different from the data released by the Changsha Bureau of Statistics on consumption classification, this paper obtained more accurate evaluation on the urban resident's entertainment consumption expenditure in Changsha City, which is measured by 3 aspects: gender, age and income difference.(2) Based on the survey data, the regression models were constructed between the income and the resident's entertainment consumption with regard to age and gender, respectively. (3) By analyzing the properties of regression models, some interesting principals were revealed which exist in the practical resident's entertainment consumption of Changsha. The results in this paper play an important and helpful role in the optimal decision-making of the government departments in Changsha.
