摘要 基于清华大学金融科技研究院互联网金融研究中心网络借贷平台数据库与网贷之家相关平台统计数据,通过构建Logit模型与Cox比例风险回归模型来研究2015年12月e租宝事件和2018年6月备案延期后的“爆雷”现象,本文着重考察投资者是否具备根据信息披露程度识别问题平台和正常平台的能力。本文发现,第一,信息披露程度是影响平台风险的重要因素:信息披露程度越高的平台,其运营时间越长,出现问题的可能性越低。第二,信息披露程度越高的平台对抗风险的能力越强。风险传染期内,信息披露程度较高的平台,其成交量受市场负面情绪的影响较小。上述两点表明,总体而言,投资者重视平台披露的信息,并具备一定的信息识别能力。最后本研究也发现,上述两次风险事件期出现的问题平台是市场出清所需,它们和正常运营平台存在较大差异,尚无证据表明大量正常平台被拖累成问题平台。

Abstract:  Based on the database of Fintech research center, National Institute of Financial Research, Tsinghua University and other statistical P2P data, this paper focuses on investor's ability to identify risky platforms and normal platforms according to the degree of information disclosure. Constructing the logit model and the Cox proportional risk regression model to study the Ezubao event in December 2015 and the “explosion” phenomenon after the record postponement in June 2018,this paper examines the relationship between information disclosure, risk and trading volume of platforms. It is found that information disclosure is an important factor affecting platforms' risk. The higher degree of platform information disclosure, the longer the operation time is, and the lower the possibility of risk. In addition, the higher the degree of information disclosure, the stronger the ability to resist risks. During the period of risk contagion, the higher the degree of information disclosure, the higher the platform turnover is, and less influenced by the market's negative emotions. These two points indicate that investors attach importance to information disclosed by platforms and have certain ability to identify information. Finally, it is also found that there are significant differences between the risky platforms that appear in the two risky events and those that are still in normal operation, indicating that it is a normal phenomenon of market clearance. There is no evidence that a large number of normal platforms have been dragged into risky platforms.
