摘　　要：利用新一代信息技术打造的虚拟集聚增强城市经济系统内在稳定性和发展韧性,已成为推动经济高质量发展亟待解决的关键问题。通过将集聚外溢衰减效应纳入虚拟集聚指标构建中,考察虚拟集聚对城市经济韧性的影响效应、作用机制和约束条件。研究结果表明:虚拟集聚显著促进了城市经济韧性提升,缓解了地理集聚溢出的空间距离约束,存在正向空间溢出效应。异质性分析表明,虚拟集聚的韧性提升效应随着虚拟集聚的深化发展不断减弱,具有正向边际递减的非线性特征,并且受城市区位和市场化程度约束存在差异,对非中心城市、东部城市和市场化程度高的城市促进作用更加明显。机制分析发现,劳动、资本和技术要素配置效率提升是虚拟集聚影响城市经济韧性的重要机制。因此,要顺应产业集群虚拟化趋势,依托互联网平台加快虚拟集聚进程,借助要素的有序流动和优化配置,适度平衡城际间经济韧性差距,实现城市经济韧性水平的共同提升。In recent years,increased Sino-US trade frictions,geopolitical conflicts,and other external factors have notably raised the risks to China’s economic stability.Addressing these complex domestic and global challenges has underscored the importance of enhancing urban economic resilience.The rapid advancement of new-generation information technology is reshaping traditional production models and methods of resource allocation,evolving geographic agglomeration into a new form:virtual agglomeration.Virtual agglomeration preserves the benefits of physical clustering but introduces unique advantages,such as efficient resource integration and enhanced knowledge spillovers.As a result,harnessing the virtual agglomeration platforms enabled by these technologies to reinforce urban economic stability and resilience has become a key priority for China to support high-quality economic development.To investigate this,we incorporate the spatial agglomeration spillover attenuation effect into constructing virtual agglomeration indicators,reflecting industrial digitalization.Using panel data from 285 Chinese prefecture-level cities and business registration data from 2013 to 2021,we empirically examine the impact,mechanisms,and constraints of virtual agglomeration on urban economic resilience.The main conclusions are as follows:(1)Virtual agglomeration significantly improves urban economic resilience by overcoming the spatial limitations of geographic spillovers,displaying a positive spatial spillover effect.(2)Heterogeneity analysis shows that while virtual agglomeration initially strengthens resilience,its effect weakens as it deepens,following a non-linear trend with diminishing positive marginal returns.This effect is more evident in non-central,eastern cities,and those with higher marketization.(3)Mechanism analysis identifies that enhancing the allocation efficiency of labor,capital,and technology is a crucial pathway by which virtual agglomeration influences urban economic resilience.Compared to prior research,this paper�
