中文摘要：

互联网金融正在中国经济体制下迅猛发展,对整个金融生态产生积极影响,P2P网贷平台是其中最有活力和代表性的业务模式,而定价策略是其成功的核心要素。该文借鉴传统双边市场定价理论,建立竞争条件下P2P平台的定价模型,并就模型均衡状态的经济意义进行探讨。建模分析结果表明：均衡状态下,平台对投资人的定价低于平台对借款人的定价;平台的利润与平台的差异化程度正相关;平台低于竞争对手定价时,将赢得更多的市场份额。相关理论结果可很好地解释现存P2P平台的不对称定价、产品差异化和价格战等实践。

英文摘要：

Internet finance is rapidly growing under China＇s financial system,and is making great positive impact on the entire financial ecology.P2 Plending network platform is one of the most vibrant and representative business models.However,one of the key factors to success for P2 Ponline lending is the pricing strategy.A pricing model was established for P2 Ponline lending for competitive conditions in this paper.The results show that at an equilibrium level,the level of pricing at which investors being charged by the platform is lower than that of borrowers and that the platform＇s profit is positively correlated with the level of its differentiation,with the platform winning more market shares by lowering its price.The theoretical analysis gives hint on some current practices,such as asymmetric pricing,product differentiation and the price war.
