为揭示住房信息传递过程,进行了住房信息扩散程度的测算。提出了住房信息扩散程度测算方法,设计和实施了针对北京二手房交易过程的实验,搜集实验数据测算和分析住房信息扩散程度。研究表明: 在实验市场中二手房信息扩散程度表现为预测价、报价、成交价与二手房价值的偏差平均每实验年缩小1.52、 2.41和0.67万实验元; 在二手房使用寿命临近期满时,二手房信息完全扩散到所有非知情交易人;在信息传递过程中,二手房信息的扩散会经历反复,信息扩散程度存在波动,但波动幅度较为稳定。

Housing information diffusion was measured to evaluate housing information transmission in Beijing. The information was measured based on Beijing's resale housing transactions. The results indicate that the degree of information diffusion for resale housing shows that the average variation of the predicted housing price was 15,200 experimental Yuan, of the offering price was 24,100 experimental Yuan and of the trading price was 6,700 experimental Yuan. The results also showed that the housing information diffused into all uninformed traders by the end of the resale housing's residual service life. The direction of the information diffusion varied and its degrees fluctuates, but the fluctuations tended to remain stable.
