电商发展促进区域数实融合的影响机制研究

Research on the Impact Mechanism of E-Commerce Development on the Integration of Digital and Real Economy in Regions

摘要: 在数字经济时代，电子商务作为连接市场端与生产端的关键纽带，其发展水平直接关系到数字经济与实体经济的融合深度。本文基于2010~2023年中国地级市面板数据，采用双向固定效应模型，系统考察了电子商务发展对区域数实融合的影响效应、内在机制及其异质性特征。研究发现：电子商务发展能够显著促进区域数实融合，且该效应通过扩大消费需求和带动数字金融两条路径实现。异质性分析表明，这一促进作用在非智慧城市、五大城市群以及制造业基础较强的城市中更为显著。本文揭示了电子商务发展驱动区域数实融合的内在机制，为各地区因地制宜推进数实融合、发挥电商的普惠效应提供了政策启示。

Abstract: In the era of digital economy, e-commerce, as a crucial link connecting the market and production ends, its development level directly affects the depth of integration between the digital economy and the real economy. Based on the panel data of prefecture-level cities in China from 2010 to 2023, this paper uses a two-way fixed effect model to systematically examine the impact, internal mechanism and heterogeneous characteristics of e-commerce development on regional digital-real integration. The research finds that the development of e-commerce can significantly promote regional digital-real integration, and this effect is achieved through two paths: expanding consumer demand and driving digital finance. Heterogeneity analysis shows that this promoting effect is more significant in non-smart cities, the five major urban agglomerations, and cities with a strong manufacturing base. This paper reveals the internal mechanism by which e-commerce development drives regional digital-real integration and provides policy implications for regions to promote digital-real integration in a targeted manner and leverage the inclusive effect of e-commerce.
