摘要:

在分析2011、2020年中国城市技术创新网络结构演化特征的基础上，运用“容量-负荷”级联失效模型与二次指派程序（QAP）从内生网络结构与外生多维邻近的双视角探讨网络结构韧性的影响机制。研究结果表明：①中国城市技术创新网络向紧密性提高、韧性提升的方向演进；②创新网络结构韧性受内生结构参数与外生多维邻近机制的复合影响；③仿真结果表明，节点抗风险能力、节点重要性、网络密度、网络层级性均与网络结构韧性具有正相关关系；④QAP结果表明，创新网络边韧性摆脱地理依赖，创新、产业、知识和经济邻近对其具有显著影响。

Abstract:

On the basis of analyzing the evolution characteristics of China's urban technology innovation network structure in 2011 and 2020, using the "capacity-load" cascading failure model and the quadratic assignment procedure (QAP) to discuss from the dual perspectives of endogenous network structure and exogenous multidimensional proximity to find he impact mechanism of network structural resilience. The research results show that: ① China's urban technology innovation network evolves towards tightness and resilience. ② The structural resilience of innovation network is affected by the composite effect of endogenous structural parameters and exogenous multi-dimensional proximity mechanism. ③ Simulation results show that node anti-risk ability, node dependency mode, node importance, network density, and network hierarchy are all positively correlated with network structural resilience. ④ QAP results show that innovation network edge resilience gets rid of geographical dependence, and innovation, industry, Knowledge and economic proximity have a significant impact on it.
