基于实验经济学的住房信息搜寻效率研究

The inefficiency of housing information search hinders the healthy development of housing market. The purpose of this project is to research the process and efficiency of housing information search in housing market with the application of experimental economic methods. Firstly, on the basis of the market survey on the process and efficiency of housing information search, with reference to the classical experimental framework, a group of testing experiments will be carried through and then a basic experimental framework will be constructed for this project. Secondly, taking into account the characteristics of current realities in housing market transactions, a series of experiments aiming at the information search process will be developed. With the experimental results, the process and efficiency of housing information search will be evaluated as well as its related influential factors, then the suggestions on the measures of improving housing market information efficiency will be put forward. Lastly, taking these suggestive measures as input to the basic experimental framework, the implementation effects of the measures will be verified and evaluated, a new round of serial experiments can be conducted when necessary. This project in attempt to apply experimental economics methods to study the process and efficiency of information search in housing market, will be able to provide new theoretical supports for improving information efficiency of housing market and new approach in the research field of housing market information.

住房信息搜寻效率低下严重阻碍了住房市场的健康发展。本项目基于实验经济学方法研究住房市场的信息搜寻过程与效率。首先，在调研住房信息搜寻过程与效率现状的基础上，借鉴经典实验框架，通过一系列测试性实验构建出本研究的基本实验框架；第二，结合当前住房市场交易的特点，开展一系列针对住房信息搜寻过程的实验，利用实验结果分析住房信息搜寻的过程、效率及其影响因素，提出提高住房信息搜寻效率的措施建议；最后，将措施建议输入基本实验框架，检验并评价所提措施建议的实施效果，必要时进行新一轮的系列实验。本项目尝试运用实验经济学方法研究住房信息搜寻过程与效率问题，以期为提高住房市场信息效率提供新的理论支持，为住房市场信息问题的研究提供新的途径。

住房信息搜寻效率低下严重阻碍了住房市场的健康发展。本项目借鉴经典实验框架，通过一系列测试性实验构建基本实验框架；结合当前住房市场交易的特点，开展住房信息搜寻过程实验，利用实验结果分析住房信息搜寻的过程、效率及其影响因素，提出提高住房信息搜寻效率的措施建议；实验检验所提措施建议的实施效果。本项目运用实验经济学方法研究住房信息搜寻过程与效率问题，可以为提高住房市场效率提供新的理论支持，为研究住房市场信息问题提供新途径。.项目组提出了住房市场搜寻效率及指标的定义和测算方法，设计并开展当前住房市场信息搜寻效率的实验，全面评价了当前住房市场信息搜寻效率及其影响因素；从价格离散程度、价格信息传递、价格趋势预期和住房信息服务对住房信息搜寻效率的影响等角度完成系列实验的设计与实施。.研究表明：当前住房信息搜寻效率一般，主体投入度和环境因素的影响较大；价格离散程度扩大将显著提高住房市场搜寻行为强度并降低搜寻匹配优度，中介效应明显；价格信息公开能有效降低寻行为强度并显著提升搜寻效率；与下跌相比，价格预期上涨情形下的搜寻行为强度较低且搜寻匹配优度较高；信息不对称通过影响市场匹配优度及搜寻成本来影响住房市场搜寻效率；互联网自助交易平台不能完全替代中介信息服务；与双向代理相比，单向代理模式的住房信息偏离度显著降低，有效减少中介信息服务的道德风险；多重上市信息服务系统（MLS）平台促进市场良性竞争，有效提高住房市场搜寻效率。.项目建议：加大住房信息披露监管力度，发挥市场公允价值的指导作用，把控价格离散的不利影响；更加快速、准确和细化地传递住房质量信息和价格信息；将价格趋势预期纳入住房市场调控体系，密切关注市场景气不佳时期的信息状态；将线上线下住房经纪业务有机协调，突出发挥单向代理模式的作用，加快推广MLS系统平台。
