Evolution Characteristics of Technological Innovation Network and Multi-Dimensional Proximity Mechanism of Urban Agglomeration in Shandong Peninsula
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.
