数字技术改变了产业的空间集聚吗?——基于280个地级市面板数据的考察

Does Digital Technology Change the Spatial Agglomeration of Industries?An Empirical Study Based on 280 Cities

作为一种新的资源配置方式,数字技术正在重塑中国的经济地理空间格局。通过将产业的异质性与数字产业政策纳入分析框架,研究数字技术对产业空间布局的重塑机制和内在机理。基于2011—2019年中国280个地级市的面板数据,采用SDM空间计量模型进行实证分析。结果表明:数字技术显著影响了产业的空间分布,但影响效应在不同行业表现出明显的异质性,即在促进制造业分散的同时强化了农业和生产性服务业的集聚。此外,数字产业政策在促进当地生产性服务业集聚的同时,通过影响地区间生产要素的流动,弱化了数字技术对邻近地区的空间溢出效应。研究结论为数字经济下产业的空间布局提供经验支持,也为数字产业政策的制定提供了新的思路。

As a new method of resource allocation,digital technology is reshaping China s economic geospatial patterns.This paper investigates the mechanism by which digital technology reshapes the spatial layout of industries by incorporating industry heterogeneity and digital industrial policies into the analytical framework.This study employs panel data for 280 cities from 2011 to 2019 to empirically analyze using the Spatial Dubin Model.The results indicate that digital technology significantly affects the spatial distribution of industries,but this impact is heterogeneous across industries.It strengthens the agglomeration of agriculture and productive services but promotes dispersion among manufacturing industries.Additionally,digital industrial policies promote the agglomeration of local productive service industries while weakening digital technology s spatial spillover effects to neighboring regions by influencing the flow of factors of production between regions.This study provides empirical support for the spatial layout of industries in the digital economy and includes a proposal for the formulation of digital industrial policies.
