灰色系统模型GM(1,1)在房地产预测中的应用研究
he Research of Gray System Model GM (1,1) in the Real Estate Prediction
文中根据某城市房地产业生产总值增加值的历年数据，利用灰色系统模型对房地产发展进行了预测。文中首先建立了灰色系统的预测模型，然后利用前几年的房地产业的相关数据，对2009 年各季度的房地产业生产总值增加值进行预测，预测值分别为：第一季度22.516亿元，第二季度66.78 亿元，第三季度44.5 亿元，第四季度48.21 亿元，年度预测总增加值为182.01 亿元。通过利用灰色预测模型在房地产业的预测研究，可以发现灰色预测的GM（1，1）模型具有较高的预测精度。
In this paper, a city based on the real estate industry to increase the value of GDP over the years of data, using the gray system model to predict the real estate development. First, the establishment of the forecasting model of gray system, and then use the real estate industry a few years ago the relevant data, in 2009 the quarter GDP added value of the real estate industry to predict, forecast are as follows: first quarter 2,251,600,000 yuan, 6.678 billion yuan in the second quarter, third quarter of 4.45 billion yuan, 4.821 billion yuan in the fourth quarter, the annual forecast for the total added value of 18.201 billion yuan. Through the use of gray prediction model forecasts in real estate research, the forecast can be found gray GM (1,1) model with high prediction accuracy.
