The results of the alternative variable method.

This study examines the influence of digital government initiatives on corporate total factor productivity (TFP). Employing a difference-in-differences (DID) methodology and analyzing data from publicly listed companies spanning the period 2010 to 2020, we investigate the impact of digital governance on corporate TFP. Our findings reveal a noteworthy positive effect, with an average TFP increase of 5%. Further exploration through heterogeneity analysis indicates that this impact is particularly pronounced in regions with robust network infrastructure, increased marketization, and decreased economic uncertainty, particularly among privately-owned enterprises. Moreover, we identify key mechanisms through which digital governance fosters this enhancement in TFP, including the facilitation of technological innovation, efficient allocation of high-skilled labor, and improved investment efficiency. Our research underscores the significant role of digital government initiatives in bolstering corporate TFP and contributes to a deeper understanding of the mechanisms underlying this relationship.

本研究考察数字政务举措对企业全要素生产率（Total Factor Productivity, TFP）的影响。本研究采用双重差分法（Difference-in-Differences, DID），对2010至2020年公开上市企业的面板数据展开分析，探究数字治理对企业全要素生产率的作用效果。研究结果显示二者存在显著正向影响，样本企业全要素生产率平均提升5%。进一步的异质性分析表明，该促进效应在网络基础设施完备、市场化程度更高、经济不确定性更低的地区尤为突出，且对民营企业的影响更为显著。此外，本研究还揭示了数字治理推动企业全要素生产率提升的核心机制，包括促进技术创新、优化高技能劳动力配置以及提升投资效率。本研究证实了数字政务举措对企业全要素生产率的提振作用，深化了对二者关系背后作用机制的理解。
