The Evolution Characteristics and Influencing Factors of Structural Resilience of China's Urban Technology Innovation Network
Based on the analysis of the evolution characteristics of China's urban technology innovation network structure in 2011 and 2020,the"capacity-load"cascading failure model and the quadratic assignment procedure(QAP)were used to discuss the influence mechanism of network structural resilience from the dual perspectives of endogenous network structure and exogenous multidimensional proximity.The research results show that:(1)China's urban technology innovation network evolves towards the direction of 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 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.
