虚拟集聚能提升产业链韧性吗?——来自中国城市面板数据的实证检验

Can Virtual Agglomeration Enhance the Resilience of the Industrial Chain?Empirical Test Based on Panel Data of Cities in China

数字经济背景下,虚拟集聚凭借其独特的网络与平台优势,已然成为产业链韧性提升的重要驱动力。本文基于2004-2019年中国278个城市面板数据,实证检验了虚拟集聚对产业链韧性的影响效应及作用机制。研究结果表明:虚拟集聚能够显著提升城市产业链韧性,且存在明显的“马太效应”,产业链韧性越强的城市,虚拟集聚对产业链韧性的提升作用越强;机制检验表明,虚拟集聚通过平台赋能效应和知识溢出效应提升产业链韧性;异质性分析表明,虚拟集聚对产业链韧性的提升作用在2015年之后、经济发展水平较高的地区与产业结构更高级的地区更显著。本研究为虚拟集聚赋能产业链韧性提升,以实现产业链现代化和高质量发展提供理论支撑和经验依据。

In the context of the digital economy,virtual agglomeration,with its unique network and platform advantages,has become an important driving force for enhancing the resilience of the industry chain.Based on the panel data of 278 cities in China from 2004 to 2019,this paper empirically tests the impact and mechanism of virtual agglomeration on the resilience of the industrial chain.The results show that virtual agglomeration can significantly improve the resilience of urban industrial chains,and there is an obvious“Matthew effect”,that is,the stronger the resilience of the industrial chain is,the greater effect of virtual agglomeration on it is.The mechanism test shows that virtual agglomeration improves the resilience of the industrial chain through the platform empowerment effect and knowledge spillover effect.The heterogeneity test shows that the effect of virtual agglomeration on the resilience of the industrial chain is more significant after the year of 2015,in the regions with higher economic development level and regions with more advanced industrial structure.This study provides theoretical support and empirical basis for virtual agglomeration to empower the resilience of the industrial chain and ultimately to realize the modernization and high-quality development of the industrial chain.
