Abstract This paper constructs local and transboundary network of green technology innovation cooperation in the Yangtze River Delta, and explains the characteristics of network structure evolution and space linkage mechanism. The results show that: 1) The local network tends to be mature, and presents in space the coreperiphery structure and the strong-strong connection between the core nodes; The transboundary network grows rapidly, and the spatial characteristics are from sparse radial, supplemented by sparse closed-loop innovation links. 2) The interaction between local and transboundary network is enhanced. The development of transboundary network also gradually increases the average network status of node cities in the local network. 3) Cities with high network status in local network play the role of "middleman" in localtransboundary network, and cities with high recursive centrality high recursive power play the role of technology goalkeeper in local-transboundary network.
