摘　　要：近年来,创新网络作为区域和城市创新驱动力的重要性得到了广泛关注。一些研究将网络关系视为知识在城市内和城市间传播的渠道,并通过网络分析视角洞察城市创新的结构和动态。然而,城市创新的网络机制,特别是数字经济发展背景下的数字赋能城市创新能力提升机制还有待进一步研究。本文利用长三角城市群26个城市2009年—2018年联合申请专利数据构建了城市创新网络,探讨了网络结构属性——小世界和结构洞对城市创新能力的影响。结果表明,小世界与城市创新能力呈“倒U型”关系,数字经济发展水平正向调节了二者之间的“倒U型”关系,结构洞对城市创新能力具有正向影响。本文厘清了创新网络结构对城市创新能力的影响,回应了以往研究关于小世界和结构洞对创新影响的理论争议,为区域创新的理论研究提供了新颖性观点,深化了对城市群创新发展规律的认识,对推进中国城市群协同创新具有重要意义。The importance of urban innovation networks as drivers of regional and urban innovation has attracted significant attention.From a regional perspective,urban innovation networks are defined as systems of urban nodes interconnected through patent collaboration among heterogeneous innovation agents.A growing number of studies have applied a network-analytics perspective to capture the structure and dynamics of urban innovation networks,which are viewed as channels through which knowledge can diffuse within and across cities.Although a rich literature devoted to these themes exists,it does not offer conclusive evidence of how network structures affect urban innovation capability.Especially in the context of development of the digital economy,the effect of urban innovation′s network mechanism on urban innovation capability remains uninvestigated.Digital technology has compressed the spacetime distance through efficient information transmission and facilitated the interconnection of cities and the flow of resources.The double overlay of the digital economy and innovation networks presents opportunities and challenges for urban innovation research.To address this issue,this study explores the impact of network structural attributes—small worlds and structural holes—on urban innovative capacity based on the ten-year panel data of 26 cities in the Yangtze River Delta urban agglomeration.The remainder of this paper is organized as follows.First,we develop the theoretical concepts subject to testing.This section examines the small worlds and structural holes,arguing why they matter for urban innovation capability,and elaborates on the corresponding hypotheses.Second,this study constructs urban innovation networks based on the 2009-2018 collaborative patent application data of 26 cities in the Yangtze River Delta urban agglomeration.Third,we describe the structural properties of innovation networks by employing the social network analysis method and selects small worlds and structural holes as explanatory variables;ur
