Research on income inequality in China——an analysis by Lorenz curve;

To characterize scale-free network topology more intuitively and profoundly,Lorenz curve and Gini coefficient which describe income inequality in economics are generalized into complex networks where people in economics are corresponding to nodes in networks and income is corresponding to node degree.

Based on the land use data of each county,we introduced the concept of Lorenz curve and Gini coefficients(GC) to analyze the land use distribution in Beijing mountain area.

The Lorentz curve and its derived Kiny factor are separately used to visually describe and quantitatively determine the differential allocation of revenue in economics.

The principle of Lorentz curve analysis is introduced, and several problems that must be noted during analyzing reservoir water absorbtion are discussed with examples.

With Lorentz curve,this paper probes the proportionate factor of the per capita net income to the per capita living space.

In the paper,we use the data obtained by the remote sensing investigation for state land resources and environment, which is a key project in China eighth five-year-plan of science and technology program, to study the spatial pattern of land resources in Jiangxi province by our spatial Lorenz curve.
