Estimating Lorenz Curve of Income in China by Cubic Spline Interpolation
In this paper, we use a kind of cubic-spline-interpolation to approximate the Lorenz curves of urban and rural area in China, respectively. According to the Gini index reported by State Statistics Bureau of China in January 2014, we aggregate the Lorenz curves of urban and rural area in China, and obtain the national Lorenz curves of whole China from 2003 to 2013.
