摘　　要：为研究信息不对称下住房市场交易行为,得到供求双方交易信息成本的计算方法,该文利用北京市2000—2008年住房市场数据和Hedonic模型,对表征交易信息成本的参数进行估计,进而测算双方交易信息成本。研究表明:信息不对称对交易双方均会带来信息成本。供给方与需求方的交易信息成本分别为市场交易价格的15.2%和19.1%。这意味着:在信息不对称的住房市场中,需求方处于劣势地位。为降低供求双方交易信息成本,建议:拓展市场信息传递渠道,提高信息传递效率;加大对住房供给方的信息披露,弱化需求方的信息劣势程度。The transaction activities in a housing market with asymmetrical information were analyzed to estimate the transaction information costs of both the supply and demand sectors. Beijing housing market data from 2000 to 2008 was then input into a Hedonic model to estimate the variables affecting the transaction information costs. The results indicate that the asymmetrical information increases the information costs on both sides. The information cost for the supply sector is 15.2% of the transaction price while that for the demand sector is 19.1%, which shows that the demand sector is at a disadvantage in a housing market with asymmetrical information. Suggestions to reduce the information costs include improving the transmission channels of market information and the transmission efficiency to give more publicity to the supply sector; therefore, reduce the disadvantages on the demand side.
