摘　　要：现有研究大多基于网络拓扑结构视角来评估节点重要度,忽略了网络动态变化特征对节点重要度评估结果的影响,而基于网络动力学视角来识别关键节点的研究主要针对的是抽象网络,应用在现实网络中则存在一定的局限性.鉴于此,基于级联失效视角来识别新能源汽车研发网络的关键节点企业.首先,利用新能源汽车合作专利数据构建真实的新能源汽车研发网络.接下来,从界定节点企业初始负荷、确定节点企业容量、建立负荷分配规则三个方面提出级联失效模型,进而采用数值仿真方法揭示蓄意攻击和随机攻击策略下新能源汽车研发网络上的级联失效过程及其规律.最后,通过对新能源汽车研发网络进行数值仿真,识别出新能源汽车研发网络的关键节点企业.该研究成果对预防因关键节点企业失效而引发的级联失效现象进而提升新能源汽车行业的安全韧性水平具有重要的参考价值.networks to identify key nodes,and have some certain limitations to be applicated in real networks.Therefore,this paper identifies key node enterprises of the new energy vehicle research and development network based on the perspective of cascading failures.Firstly,this paper builds a real new energy vehicle research and development network by using new energy vehicle cooperation patent data.Then,a cascade failure model is proposed from three aspects: Defining the initial load of the node enterprise, determining the capacity of the node enterprise,and establishing load propagation rules. Next, numerical simulation method is used to revealthe cascade failure process and rules of the new energy vehicle R&D network under deliberateand random attack strategies. Finally, a simulation analysis of a real new energy vehicle researchand development network is conducted to identify the key node enterprises of the new energyvehicle research and development network. The research results have important reference valuefor preventing large-scale cascading failures caused by the failure of some key node enterprisesand ensuring the normal cooperative development of new energy vehicle node enterprises.
