摘要
在数字经济与全球供应链不确定性交织的时代背景下,探究数字空间虚拟集聚如何重塑城市创新体系并增强实体经济韧性,已成为重大的理论与现实议题。基于2013—2023年中国282个地级市的面板数据,运用双向固定效应模型,实证考察数字空间虚拟集聚对城市创新边界的影响效应和作用机制。研究发现:第一,数字空间虚拟集聚能够显著拓宽城市创新边界。第二,数字空间虚拟集聚主要通过加速知识溢出和促进知识多样化两条渠道来拓展城市创新边界,且并未对城市原有的知识专业化优势产生挤出效应。第三,数字空间虚拟集聚的创新边界拓展效应呈现出显著的区域、等级与禀赋异质性,在东部地区、中心城市、非资源型城市和数字基础设施完善的城市中作用更为突出。第四,被拓宽的城市创新边界能有效转化为实体经济的优势,显著增强了城市供应链韧性,尤其是适应调整能力与创新发展能力。研究结论为各级政府制定适应新发展格局的“无界创新”战略和产业安全政策提供了经验证据。
The simultaneous development of the digital economy and increase in global supply chain uncertainty has made exploring how virtual agglomeration reshapes urban innovation systems and enhances the real economy s resilience a matter of critical theoretical and practical consequence.Using panel data for 282 prefecture-level cities in China from 2013 to 2023 and a two-way fixed-effects model,this study empirically examines virtual agglomeration s impact on urban innovation boundaries and the underlying mechanisms of that impact.The study produces four main findings.First,virtual agglomeration significantly broadens urban innovation boundaries.Second,this effect occurs primarily through two mechanisms:accelerating knowledge spillovers and promoting knowledge diversification without creating a crowding-out effect that impedes cities established specialization advantages.Third,virtual agglomeration s boundary-expanding effect is heterogeneous.It is more pronounced in eastern regions,central cities,non-resource-based cities,and cities with advanced digital infrastructure than in other types of cities.Fourth,innovation boundaries expanded by virtual agglomeration,in turn,yield real economy s advantages by significantly enhancing urban supply chain resilience,especially in terms of adaptive capacity and innovative development.This study provides empirical evidence and insights for policymakers to formulate“borderless innovation”strategies and industrial security policies adapted to the new development pattern.
