Incorrectness of tradition Engel's Coefficient is that it expresses only the quantity not the quality of food consumption in food expenditure.

Generally,it is believed that the development and enjoyment of consumption will increase along with the Engel Index decline.

Regress analysis on the amelioration model of Engel Coefficient;

The Applicability of Measuring the Living Standard of Urban Residents by Using Engel Coefficient;

The tendency and effect of urban households Engle coefficient in Fujian;

The Application Deficiency and its Reason of Engle Coefficient in China;

In this paper,Fujian urban household s Engle coefficient is forecasted by linear regression model,gray system model,genetic algorithms back propagation network (GABP) model and linear combination model.

Sample data of consumption structure about rural residents in Shaanxi Province was used and the Engel coefficient was chosen as a research indicator to do empirical analysis and verified the results from three aspects:the Engel coefficient of linear regression,Marginal propensity to consumption and the income elasticity.

Through the study and analysis of the family members annual average income of the citizens in cities and towns, the local average GDP per person, and the Engel coefficient, this paper is an attempt to explore closely the relationship between these factors and the prices of houses in cities and towns.
