As the cascading failures of the R&D network may lead to severe consequences, it is necessary to propose a mitigation strategy to keep it safe. According to the previous research, we develop a R&D network based on the BBV generation algorithm and propose the mitigation strategy on protecting some enterprises to avoid the cascading failures, then we explore the effects of mitigation strategy under different values of some critical parameters through numerical simulation. The simulation results show that the HP strategy is the best, followed by the KP strategy and RP strategy, parameter ζ and μ are two critical parameters related to the process of the cascading failures of the R&D network. This paper can provide a useful theoretical basis to protect the safety of the enterprises of the R&D network and improve the R&D efficiency.
