Abstract: As part of the Internet financial, P2P network lending develops rapidly in recent years However, P2P network lending encounters such problems as lack of relevant laws and regulations, which block the development of P2P As the regulatory rules will be soon made, the development trend of P2P attracts much attention To make accurate predictions of P2P, the growth model of P2P network lending platform is built based on the knowledge of system dynamics, and through the system simulation, it is predicted that the number of P2P network lending platforms first maintains a sustainable growth and then has a rapid decline

Key words: P2P, network lending platform, system dynamics, system simulation
