基于2014~2021年中国地级市数据，研究发现：数字政府建设显著提升了地区招商引资水平，不仅能够吸引并留住异地企业，且在“补贴式”水平较低时效果更显著。机制分析表明，数字政府建设通过提高财政透明度、完善法治、增强市场公平性及降低市场分割度，促进了招商引资。此外，数字政府还推动了本地创新与创业活力，助力产业结构高级化与合理化，为高质量招商引资提供了坚实保障。

Based on data from Chinese prefecture-level cities between 2014 and 2021, this paper finds that digital government construction significantly enhances regional investment attraction, particularly when “subsidy-based” levels are low. Mechanism analysis reveals that digital government construction promotes investment attraction by improving fiscal transparency, strengthening the rule of law, enhancing market fairness, and reducing market segmentation. Additionally, digital government drives local innovation and entrepreneurial vitality, facilitates industrial structure upgrading and rationalization, and provides a solid foundation for high-quality investment attraction.
