Prediction of Low-Rent Housing´s Supply Quantity Based on Grey Systems Theory

In this paper, we use grey GM (1, 1) model to predict low rental housings´ supply quantity in Beijing from 2013 to 2015.Firstly, we give a brief introduction of renewal grey GM (1, 1) model and its methodology. Secondly, we use per capital floor space of urban residential buildings and non-agricultural population as basic data to predicts Beijing´s total housing supply from 2014 to 2016. Finally, we use grey GM (1, 1) model predict the number and the area of low rent housings´ supply target in Beijing.
