摘要：
Establishing research and development relationships with other firms have been an investable trend for firms to gain competitive advantages. However, risk propagation leads to the high failure rate of R&D network. To analyze how indirect relationships influence on risk propagation in research and development (R&D) network, this paper proposes two methods to measure the indirect relationships from two dimensions of firms and risks. Based on this, the R&D network risk propagation model is built from three aspects, which are the definition of risk load, the definition of risk capacity, and how risk occurred firms trigger other firms to occur risk. Then, the mechanism of risk propagation is analyzed by numerical simulations based on empirical and simulated R&D networks. The research results show that the indirect strength of firms has a negative impact on the robustness of R&D network under risk propagation, but it has a positive impact on the range and speed of risk propagation. However, with the increasing of the number of indirect paths between firms, the effect on the robustness of R&D network, the propagation range and the speed of risk propagation will show a diminishing marginal effect. Thus, firms should also pay more attention to risk status of these indirect cooperation firms with common partners. When considering risk loss interactions, and firms take account the additional losses caused by risk interactions into risk capacity, which will improve the robustness of R&D network. It is essential for firms to add the additional loss caused by risk interactions in risk prevention measures. The difference effect of three attack strategies on the robustness of R&D network under risk propagation will gradually disappear with the increase of the number of indirect path lengths between firms, which indicates that firms in any position in a particular network could have a great impact on the robustness of the network. © 2023 Systems Engineering Society of China.
