摘　　要：创新是城市与区域发展的核心动力,城市创新体系是提升区域创新能力的重要支撑,以科研合著论文为媒介的创新网络是研究城市创新系统的重要视角.以2006-2020年成渝地区双城经济圈城市间论文合著数据构建知识创新网络,运用社会网络分析方法对该区域知识创新网络的整体特征、网络中心度和网络结构等方面进行分析,从而揭示成渝地区双城经济圈知识创新网络的动态演化规律.研究发现:(1)该区域整体网络密度偏低,呈现缓慢增长趋势,整体网络凝聚力不断增强,呈现“小世界”特性;(2)知识创新网络从“单中心、低层次”发展为“多中心、多层次”,双核城市成都和重庆创新极化效应显著,节点城市的中心性均有提升;(3)知识创新网络结构呈现“核心-边缘”特征,区域内创新联系多发生在核心区的节点城市,空间分布不均衡,呈现出西部紧密、东部稀疏的格局.Innovation is the core power of urban and regional development.The urban innovation system is an important support to improve regional innovation ability,and the innovation network based on scientific research co-authored papers is an important perspective to study the urban innovation system.This paper constructed a knowledge innovation network based on the co-authorship data of Chengdu-Chongqing economic circle between 2006-2020,using the social network analysis method on the overall characteristics of the regional knowledge innovation network,network center,network structure was analyzed,so as to reveal the dynamic evolution law of Chengdu-Chongqing economic circle and the knowledge innovation network.The results showed that:(1)The overall network density in this region was low,showing a slow growth trend,and the overall network cohesion was increasing,showing a “small world” characteristic;(2)The knowledge innovation network develops from “single-center,low-level” to “multi-center,multi-level”.The innovation polarization effect of dual-core cities Chengdu and Chongqing was significant,and the centrality of node cities was improved.(3)The structure of the knowledge innovation network was core-edge.The innovation links in the region mostly occur in the node cities in the core region,and the spatial distribution was unbalanced,showing a tight pattern in the west and sparse in the east.
