二手房市场非居间化对中介信息服务的挑战
Challenge of disintermediation to the information service of brokers in the second-hand house market

随着互联网自助交易平台的不断发展，二手房市场非居间化成为学者以及业界广泛关注的话题。该文利用实验经济学模拟互联网自助交易平台以及中介信息服务平台，并对2个市场的信息偏离度、市场匹配优度以及市场效率进行计算，探讨住房市场互联网自助交易平台对中介信息服务的挑战。结果表明：互联网自助交易平台的市场信息不对称问题更为严重；利用中介信息服务平台的市场更接近于Pareto最优情形；中介信息服务平台的市场效率显著高于互联网自助交易平台。因此，互联网自主交易平台不能替代中介信息服务平台，中介信息服务平台应加强对二手房市场信息的鉴别及披露，从而提高市场效率。
Abstract：As the internet develops, more and more people are paying attention to disintermediation on the second-hand house market. This paper studies the difference between markets with automated trading platforms and those with broker information services using experimental economics. The results show that the problem of asymmetric information is worse in a market with automated trading platforms than with broker information services. Markets with broker information services are closer to the Pareto equilibrium than with automated trading platforms. Markets are less efficient with automated trading platforms than with broker information services. Thus, internet self-help trading platforms can not replace broker information services. Brokers should improve information quality to improve market efficiency.
