Under the multi-agent network cooperative innovation mode of cross-domain and cross-border,the embedded risk is accompanied by the whole process of technological innovation network evolution,which restricts the stable operation of innovation network.The patent cooperation data of China's new energy automobile industry from 2009 to 2020 are used to construct the industrial technological innovation network,and the evolution of technological innovation network is divided into three stages based on patent statistics and industrial key policies.Starting from the two embedding dimensions of structure and relationship,and further considering the cascading failure process of relationship embedding,the changes of innovation network structure and function under embedded risk are simulated and analyzed.It is found that the structural embeddedness of large group enterprises and enterprises in monopolistic resource industries is easy to cause embedded risks,which have strong destructive effects on the network structure of industrial technological innovation.The network structure evolves rapidly from integration to fragmentation,and the evolution speed gradually acceler-ates with the highlighting of the network'score-periphery'structure.The structural embedding behavior of enterprises in the industrial chain has a promoting effect on the stability of innovation network,and gradually increases with the emergence of network'periphery-multi-core'structure;the relational embeddedness behavior of innovation subjects helps the evolution of innovation network structure from simple looseness to loose coupling,and strengthening the governance of weak relations in the network can promote the stability of industrial technology innovation network.
