Synergistic evolution of knowledge network and knowledge production of cit-ies:A case study of the three major urban agglomerations in China
In the knowledge economy era,the interplay between knowledge network embeddedness and cities'knowledge production is crucial but understudied.This paper examines this relationship in 62 cities within China's the Beijing-Tianjin-Hebei,the Yangtze River Delta,and the Pearl River Delta urban agglomerations.Using patent transfer data from 2001 to 2020 to model urban networks and measuring knowledge production by patent applications,we apply stochastic actor-oriented models to analyze the co-evolution of network em-beddedness and knowledge production.Three conclusions are drawn:1)The empirical results show a co-evolu-tion characteristic that mutual promotion between knowledge network and knowledge production.The im-provement of knowledge production in cities increase the probability of establishing knowledge network link between cities,at the same time the embedding characteristics in knowledge network will in turn further pro-mote knowledge production capacity in cities.2)The co-evolution process between knowledge network and knowledge production in cities is jointly affected by the path-dependent mechanism and the multidimensional proximity mechanism.Cities with rich knowledge network links tend to send and receive more knowledge net-work links.Cities in geographical proximity,culture proximity and organization proximity have more oppor-tunities to establish knowledge network links,but there are differences in the multidimensional proximity mechanisms of different urban agglomerations.3)The co-evolution process of cities in knowledge networks and knowledge production has heterogeneous characteristics depending on the industrial division of labor and the internal spatial structure of the city cluster in which they are located.The establishment of network links in the Beijing-Tianjin-Hebei urban agglomeration is overly dependent on the core cities of knowledge production in the agglomeration;the deep development of network links in the Yangtze River Delta urban agglomeration increases the probability of establishing network links among the edge cities of knowledge production in the agglomeration and between the edge cities and the core cities;the development of network links in the Pearl River Delta urban agglomeration show heterogeneous characteristics and the knowledge production in the edge cities is more dependent on the radiation drive of the core cities.In the future,research should use comprehens-ive metrics to provide a deep portrayal of knowledge networks and a comprehensive portrayal of the synergist-ic evolution of knowledge networks and knowledge production based on different approaches.
