摘要

为强化长三角区域绿色技术协同创新水平，以长三角区域41个地级及以上城市为研究对象，利用各城市2010—2019年联合发明专利授权数据信息，构建绿色技术创新合作的本地网络与跨界网络，诠释网络结构演变特征及本地—跨界网络空间联动机制。研究表明：①本地网络的通达性和凝聚力逐渐上升，空间上呈现以省会城市为中心的核心—边缘结构及核心节点间强—强联系格局；跨界网络的节点和关系数急速增加，空间上呈现以放射状为主，稀疏的闭环创新联系为辅的特征。②本地网络与跨界网络的交互作用增强。本地网络中参与跨界合作的节点数量越多越有利于推动区域内外城市建立正式创新合作关系。跨界网络的发展也会提高本地网络中节点城市的平均网络地位。③本地网络中网络地位高的城市扮演着本地—跨界绿色技术协同创新的“中间人”，其中处于高递推中心性高递推权力位置的城市充当着本地—跨界网络空间联动的技术守门员。

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.
