Abstract Based on the perspective of interdependent network,this paper constructs the multilayer network including collaborative network,knowledge networkand affiliation network connecting cities to knowledge elements,to analyse structure characteristics and evolution trend of the collaborative innovation network.In addition,the formation mechanism of collaborative innovation network in urban agglomeration in the Yangtze river delta is also analyzed in this paper by establishing ERGM.Using the data of industry-university-research institutes joint patent application in urban agglomeration of Yangtze river delta from 2009 to 2018,we find that:the level of collaborative innovation in the Yangtze river delta has been constantly improved,but still in weak connection.The cyberspace pattern of collaborative innovationnetwork has shifted from "three pillars" pattern to"multi-core,multi-level and balanced" pattern.With the continuous enhancement of collaborative innovation ability,technology field appears spatial aggregation,and each city has different emphases on development.The formation of collaborative innovation network is influenced by geographic homphily,knowledge uniqueness and structure embedding,and the cooperative relationship is more inclined to the intermediary 2-path.
