Abstract: A financing model for IP pledges provides SMEs with a new financing channel. However, the pledge financing process is faced with a variety of complex uncertainties, which also affects the scope of China's financing business. Firstly, this paper discusses the risks that may be faced by four entities: financing companies, financial institutions, intellectual property rights, and third party institutions in the financing process. Secondly, a relational network of risk influencing factors is established, and the weights of the influencing factors are calculated according to the analytic hierarchy process. Finally, the vensim PLE software is used to dynamically simulate the flow chart of the IP pledge financing system to obtain a description of the future behavior of the system under the influence of different influencing factors, in order to seek targeted improvements in the financing risk.
