数字地理邻近度对企业出口韧性的影响研究

Research on the Impact of Digital Geographical Proximity on Firms’ Export Resilience

摘要: 本文选取2009~2023年中国上市公司面板数据，构建数字地理邻近度指标，系统考察了数字地理邻近度对企业出口韧性的影响效果以及内在传导路径。基准回归结果显示，数字地理邻近度越高，企业出口韧性越强。机制检验表明，数字地理邻近度可通过提升分析师关注度、优化供应链集中度两条渠道赋能出口韧性。异质性分析表明，中小微、新设以及地处低数字基建城市，数字企业的赋能效果更为突出。本文丰富数字经济与出口韧性的相关研究，为各地优化数字产业空间布局提供实证支撑与政策依据。

Abstract: Based on the panel data of Chinese listed firms from 2009 to 2023, this paper constructs an indicator of digital geographical proximity, and systematically investigates its effect and internal transmission mechanisms on firms’ export resilience. Benchmark regression results indicate that higher digital geographical proximity contributes to stronger corporate export resilience. Mechanism tests show that digital geographical proximity boosts export resilience through two channels: raising analyst attention and optimizing supply-chain concentration. Heterogeneity analysis reveals that such empowering effect is more pronounced for micro, small and medium-sized enterprises, newly-established firms, and enterprises located in cities with underdeveloped digital infrastructure. This paper enriches research on the digital economy and export resilience, and provides empirical evidence and policy references for local governments to optimize the spatial layout of digital industries.
