摘要
为研究山东半岛城市群技术创新网络的整体结构、时空演化以及多维邻近性机制,文章采用社会网络分析和MRQAP模型,对 2006-2021 年 136 个县级单位间合作申请专利数据进行分析.研究结果表明:(1)山东半岛城市群技术创新网络联系强度逐步提高,通达性较好,"小世界性"显著;(2)空间异质特征明显,层次结构清晰,呈现出"核心-边缘"结构;(3)地理邻近性、技术邻近性、制度邻近性、经济邻近性和行政边界对技术创新联系具有独立影响,同时,邻近性之间对创新网络具有促进或限制的交互影响效应.
Abstract
In order to study the overall structure,temporal and spatial evolution and multi-dimensional prox-imity mechanism of technological innovation network in the urban agglomeration of Shandong Peninsula,this paper uses the social network analysis and the MRQAP model to analyze the patent application data of 136 county-level units based on the city-to-city cooperation from 2006 to 2021.Results of the study show as follows.(1)The intensi-ty of technological innovation network in the urban agglomeration of Shandong Peninsula has gradually increased,the accessibility is better,and the"small world"is significant.(2)The spatial heterogeneity is obvious,the hier-archy is clear,and a"core-edge"structure is presented.(3)Geographical proximity,technological proximity,in-stitutional proximity,economic proximity and administrative boundaries have independent effects on the technological innovation linkages,and at the same time,the interaction between proximities has an interactive effect on the innovation networks to be promoted or restricted.
