In recent years, while China’s P2P online loan platforms are greatly increasing, a lot of the platforms are closing down, and the reason for frequently closing down of P2P loan platforms needs to be deeply studied. The analysis based on 3842 P2P online loan platforms disclosed by online loan home shows that platform strength, risk control capability, business model and industry regulation significantly affect the survival status of the P2P platforms. The death risk is high and survival time is short under the situations such as insufficient registered capital, undisclosed paid-in capital, low registered regional level, no state-owned background, no listing/wind investment background, no funds deposit, no third-party guarantee/advance/insurance, no （Quality） collateral/risk reserve, with day mark/1 month mark, no automatic bidding and transfer of creditor's rights, no participation in supervision association, platform without ICP business license, among which the platforms with no listing/wind investment background, no funds deposit, no participation in supervision association, and platform without ICP business license are more severe for survival. The influence of different factors on three kinds of death status of problem platforms is different. The most risk of running is no funds deposit, no third-party guarantee/advance/insurance, no （Quality） collateral/risk reserve, and the platform without ICP business license. The most difficult cashing platforms are those which have no funds deposit, no third-party guarantee/advance/insurance, with day mark/1 month mark, no automatic bidding and transfer of creditor's rights, and no participation in supervision association. The lack of state-owned background, non participation in industrial regulatory association, and no ICP license are the main reasons for the platforms to suspend business.
