摘　　要：创新网络与区域经济韧性是经济地理学者关注的热点议题,随着数字经济的快速发展,探究数字技术创新网络对区域经济韧性的影响具有重要意义。论文以长三角41个城市为研究对象,利用2010—2021年合作创新专利和经济社会发展数据,借助社会网络分析方法、经济韧性测度指标体系,刻画了长三角城市数字技术创新网络及经济韧性时空演化特征,实证检验了数字技术创新网络结构特征对城市经济韧性的影响效应。研究发现:①长三角城市数字技术创新合作联系程度日益提高,且逐渐演化形成“核心—边缘”结构和凝聚子群结构。长三角城市经济韧性均呈现逐年稳步上升态势,但空间差异逐渐增大。②长三角城市数字技术创新网络的度数中心度和接近中心度对城市经济韧性的提升具有显著的正向促进作用,而中介中心度则对经济韧性产生负面影响,稳健性检验也表明该结论成立。③相较于中心城市,边缘城市的数字技术创新网络对其经济韧性提升影响更大,且中介中心度更加显著,这一效应与核心城市差异较大。研究结果对于厘清数字技术创新网络和经济韧性之间的关系、探索提升区域经济韧性的路径具有一定借鉴意义。With the rapid development of the digital economy,it is of great significance to explore the impact of digital technology innovation networks on regional economic resilience.Taking 41 cities in the Yangtze River Delta as the example,this study used the data of digital technology innovation cooperation patents and economic and social development from 2010 to 2021,and the social network analysis method and economic resilience measurement index,to describe the temporal and spatial change characteristics of digital technology innovation networks and economic resilience in cities in the Yangtze River Delta,and empirically test the influence of the structural characteristics of digital technology innovation networks on urban economic resilience.The results show that:1)The cooperation degree of digital technology innovation in the Yangtze River Delta was constantly increasing,and it has gradually evolved into a core-periphery structure and a cohesive subgroup structure.The economic resilience of the cities in the Yangtze River Delta has been steadily increasing through the study period,but the spatial differences were gradually increasing.2)Degree centrality and closeness centrality of digital technology innovation networks in Yangtze River Delta cities had a significant positive effect on the promotion of urban economic resilience,while betweenness centrality had a negative impact on economic resilience.Robustness test also showed that this conclusion is valid.3)Compared with the central cities,the digital technology innovation network in peripheral cities had a greater impact on their economic resilience,and the degree of intermediary centrality was more significant,which was quite different from that in core cities.This study is useful for clarifying the relationship between digital technology innovation networks and economic resilience,and exploring the path to enhance regional economic resilience.
