摘要
基于2000—2020年海洋产业合作申请专利数据,运用社会网络分析法和地理探测器,分析城市创新网络的拓扑结构、空间格局和邻近性机理。结果表明:①拓扑结构方面,2000年和2001年城市创新网络不具备无标度网络特征;2002—2020年,网络规模逐渐扩大,城市间合作增加,网络以2011年为分界点由松散转为集聚阶段。网络的无标度特性和小世界性逐渐明显,并由“双核心”结构逐渐发育为以北京为单核心的“核心-边缘”结构。②空间格局方面,核心城市和中介城市均表现出区域性特征,主要集聚在京津地区、长三角、珠三角和山东半岛,城市创新网络形成了以三角结构为支撑的四边形空间格局。③城市专利合作由沿海城市向内陆城市扩展,但海洋产业的科技创新主要依靠深圳、青岛、上海、天津、广州等沿海城市和北京、武汉等少部分内陆城市。④社会邻近性对城市创新网络的解释力最高,地理距离对城市合作的限制作用逐渐减弱,不同邻近因子间均存在非线性增强的两两交互作用。
Based on the patent application data of marine industry cooperation from 2000 to 2020,this paper analyzes the topological structure,spatial pattern and proximity mechanism of China’s urban innovation network by using social network analysis and geodetector.The results show that:①In terms of topological structure,urban innovation network does not have scale-free network characteristics in 2000 and 2001;from 2002 to 2020,the scale of the network gradually expanded,and inter-city cooperation increased.The network changed from loose to agglomeration with 2011 as the dividing point.The scale-free characteristics and small world of the network are gradually obvious,and the dual-core structure is gradually developed into the“core-edge”structure with Beijing as the single core.②In terms of spatial pattern,core cities and intermediary cities show regional characteristics,mainly concentrated in Beijing and Tianjin,Yangtze River Delta,Pearl River Delta and Shandong Peninsula.Urban innovation network forms a quadrilateral spatial pattern supported by triangular structure.③Urban patent cooperation expands from coastal cities to inland cities,but the scientific and technological innovation of marine industry mainly relies on coastal cities such as Shenzhen,Qingdao,Shanghai,Tianjin,Guangzhou and a small number of inland cities such as Beijing and Wuhan.④Social proximity has the highest explanatory power for urban innovation network,and the limitation of geographical distance on urban cooperation is gradually weakened.There is a nonlinear enhanced pairwise interaction between different proximity factors.
