Commercial Housing Price Index Forecast Based on the Gray Model

Real estate is a pillar industry of the national economy, and it plays an important role in the national economy. Commercial housing price is the most direct and the most scientific reflection of the real estate market conditions. Therefore, a scientific forecast of the price of commercial housing is very necessary. The irregular fluctuation of change in housing price makes it difficult to forecast, so this paper uses gray system prediction model to predict the price index of a certain period in the future. The results show that housing price continued to increase from 2004 to 2012, but the rise has signs of slowing down because of the implementation of national regulatory policy. The results of model prediction can give a true picture of housing price changing trend, which indicates that the gray forecasting model can effectively ensure the accuracy and effectiveness.
