摘要:本文通过实证检验了传统的商业银行贷款选择标准能否有效地帮助投资者降低贷款风险。建立了基于人人台贷款数据的Poisson和Logit回归模型,结果表明,虽然按照商业银行贷款筛选标准提供证明信息的借款人使投资者花费更多的时间进行判断,但明显减少了完成投标所需的投标人数,违约概率也较低。这表明传统的商业银行贷款选择标准在网络贷款市场上仍具有良好的适用性,为投资者提供了有效的信息审查参考,以准确判断借款人的情况,降低投资风险。

一、导言
2018年以来,P2P平台上的跑道事件频频发生。投资者在选择了高可靠性的平台后,需要在平台上选择可靠的借款人来决定是否放贷。随着政府监管力度的加强,平台风险识别的难度将进一步降低,但平台借款人的风险控制始终需要投资者自己来处理。与美国的模式不同,中国P2P的结构是大量个人投资者对大量个人借款人的响应。信息不对称在传统商业银行贷款业务和新兴的互联网金融中存在。借款人总是处于主导地位。除利率和贷款期限外,贷款的完成在很大程度上取决于投资者对借款人还款能力和信用状况的判断。商业银行作为传统的融资中介机构,已经建立了一套相对完善有效的贷款选择标准。因此,投资者能否借鉴这一逻辑体系成为本文的研究课题。
目前,关于在线借款人。以前的研究发现借款人年龄、外貌、性别[1]、职业地位[2]、社会地位资本、信用评级[3]具有较强的传导效应。在P2P借贷风险防范方面,现有的研究大多集中在网上借贷平台的风险评估上。[4,5,6]。尽管网上借贷的理论研究是越陷越深,国内的网上借贷市场依然没有像疲软的市场一样有效。投资者远未完全理性[7]。因此,帮助投资者还是很重要的提高决策效率,降低风险借款人信息研究。
基于中国P2P在线实际运营模式贷款平台业务,本文提出与类似贷款相关的待验证假设商业银行的项目,并建立了一个基于人人台20823笔贷款数据的模型站台。实证检验结果表明,传统的商业银行贷款的选择标准是好的适用于网络借贷市场,并能提供为投资者提供信息审计参考,使他们能够准确判断借款人情况,从而减少投资风险。
二、实证分析
A.假设
在网络P2P借贷市场中,投资者需要在多个借贷对象中评估借款人的还款意愿和还款能力,选择符合自身要求的借款人。当大量不同期限、不同资金需求的借款人和投资者聚集在一个单独的网络借贷平台上,无法保证还款,且由于信息不对称等因素,平台无法对违约借款人采取有效的催收机制时,投资者将自担风险,只有有单期借款需求的借款人才会有违约或不偿还贷款的动机。对于有多期资金需求的借款人,他们更可能选择建立良好的声誉。声誉状况影响投资者对借款人信用状况的判断,进而决定借款人的借款结果。另一方面,良好的声誉要求借贷者将资格证书转嫁给投资者。也就是说,多期借款人的最终效用水平与投资者根据借款人信息推断的违约概率密切相关。研究结果还从理论上强调了借款人信息披露质量的重要性以及投资者对借款人信用状况进行预筛选的重要性。
对于单期限借款人来说,如果平台能够引入有效的征管和惩罚机制,理论上可以形成威慑效应。面对严厉的处罚,不诚实的借款人不仅要偿还贷款,还要付出额外的沉重代价。因此,理性的借款人,无论是单期还是多期借款,都会选择还钱。然而,考虑到征收成本与借款人实际情况的差异,平台惩罚机制在实践中是否真的具有威慑力还需要质疑。这一客观现实也使得投资者在竞价时,即使有惩罚机制,也要认真考虑借款人的资信状况,尽可能降低投资风险。
考虑到直接观察投资者贷款标准的困难,我们从贷款完成时间和贷款人数量两个方面考察了投资者的贷款偏好。网上借贷借款人的披露信息与商业银行类似。据此,提出了待验证的假设1。
H1:在P2P贷款中,商业银行的贷款选择标准具有很好的适用性,即减少了在该信息标准下完成招标所需的时间,减少了所需的人数。
另一方面,与最终资本收益相比,借入资金能否偿还是投资者首先考虑的问题。这意味着借款人违约率直接影响投资风险。因此,可以提出假设2:
H2:在P2P贷款中,商业银行的贷款选择标准为投资者提供了降低投资风险的信息审计模型,即符合标准的借款人违约概率较低。

Abstract—This paper empirically tests whether the traditional commercial bank lending selection criteria can help investors effectively reduce lending risk. Establishing Poisson and Logit regression models based on loan data of RenrenDai, the results show that although the borrower who provides proof information according to the commercial bank loan screening criteria makes the investor spend more time to judge, it significantly reduces the number of bidders required to complete the tender, and the probability of default is also lower. This reveals that the traditional commercial bank lending selection criteria still have good applicability in the network lending market, providing investors with an effective information review reference to accurately judge the situation of borrowers, lowering the investment risk as well. Keywords—online peer-to-peer lending; commercial banks; investors; lending platforms I. INTRODUCTIONSince 2018, runway incidents on P2P platform have occurred frequently. After choosing a platform with high reliability, investors need to choose reliable borrowers on the platform to decide whether to lend funds or not. With the strengthening of government supervision, the difficulty of risk identification of the platform will be further reduced, but the risk control of borrowers in the platform will always need to be handled by investors themselves. Different from the mode in the United States, the structure of P2P in China is a large number of individual investors responding to a large number of individual borrowers. Information asymmetry exists in the traditional commercial bank lending business and the emerging Internet finance. Borrowers are always in the dominant position. Besides of interest rate and lending period, the completion of loan depends largely on investors judgment on borrowers repayment ability and credit status. Commercial banks, as traditional financing intermediaries, have established a set of relatively perfect and effective criteria for loan selection. Thus, whether investors can use this logic system for reference has become topic in this paper. At present, there are various studies on the information of online borrowers. Previous studies have found that borrowers age, appearance, gender [1], professional status [2], social capital, credit rating [3] have strong transmission effects. In the aspect of risk prevention of P2P lending, most of the existing
Caixia Zhou School of Economics and Management Nanjing University of Science and Technology Nanjing, China 1114241428@qq.com studies focus on the risk evaluation of online lending platform [4, 5, 6]. Although the theoretical research on online lending is getting deeper, the domestic online lending market is still not as effective as the weak market. Investors are far from fully rational [7]. Therefore, it is still important to help investors improve decision-making efficiency and reduce risk through information research on borrowers. Based on the actual operation mode of Chinas P2P online lending platform business, this paper puts forward the hypothesis to be verified in connection with similar loan projects of commercial banks, and establishes an empirical model based on 20823 loan data extracted from Renrendai Platform. The results of empirical test show that the traditional selection criteria for commercial banksrsquo; lending have good applicability in the network lending market, and can provide information audit reference for investors, so that they can more accurately judge the situation of borrowers, thereby reducing investment risk. II. EMPIRICAL ANALYSISA. HypothesisIn the network P2P lending market, investors need to evaluate borrowers repayment willingness and repayment ability in a number of borrowing targets, and select borrowers who meet their own requirements. When a large number of borrowers and investors with different maturities and financial needs gather in an individual network lending platform, without guaranteed repayment, and investors are at their own risk, if the platform cannot take effective collection mechanism for defaulting borrowers, due to information asymmetry and other factors, only borrowers with single-term borrowing needs will have the motivation to default or not to repay their loans. For borrowers with multi-period capital needs, they are more likely to choose to build a good reputation. Reputation status affects investors judgment on borrowers credit status, and then determines borrowers borrowing results. On the other hand, a good reputation requires borrowers to pass on qualifications to investors. In other words, the final utility level of multi-period borrowers is closely related to the default probability deduced by investors based on borrowers information. The results also theoretically emphasize the importance of the quality of information disclosure of borrowers and the importance of prescreening the credit status of borrowers by investors. For single-term borrowers, if the platform can introduce an effective collection and punishment mechanism, it can form a deterrent effect in theory. In the face of strong penalties, dishonest borrowers not only have to repay their loans, but also pay an extra heavy price. Ther 剩余内容已隐藏,支付完成后下载完整资料 资料编号:[273849],资料为PDF文档或Word文档,PDF文档可免费转换为Word |
