Risk factors of P2P platform in China based on COX model

Description

Could you help me to rewrite the literature review and write the conclusion. I bought 2200 words and I think it is enough. If you feel that some explanations are not necessary, you can delete them. It would be good if you can keep the word limit from 5000 to 6000 words. It would be great if you could help me proofread my writting. Please contact me if you need anything!
