摘要
文章基于2015—2019年沪深A股上市企业数据,实证检验了数字经济发展对企业全要素生产率的影响。研究发现:第一,数字经济发展能显著提升企业全要素生产率,在替换企业全要素生产率的指标计算方法、更换模型以及采用工具变量进行验证后结论依旧成立;第二,数字经济发展有利于提高企业技术创新水平和资源配置效率,进而推动企业全要素生产率提升;第三,数字经济发展对企业全要素生产率的促进作用会受到行业、企业产权属性以及所处地区的影响,在中高技术制造业企业、非国有企业以及东部地区企业中,数字经济发展对企业全要素生产率的提升效果更显著。
Based on the data of A-share listed companies in Shanghai and Shenzhen from 2015 to 2019, this paper empirically studies the influence of digital economy development on enterprise total factor productivity(TFP). The findings are as follows: First, digital economy development has a significant improvement effect on enterprises’ total factor productivity, and the conclusion still holds after the index calculation method of enterprises’ total factor productivity and model are replaced and the tool variables are adopted. Secondly, the development of digital economy is conducive to improving enterprises’ technological innovation level and resource allocation efficiency, thus promoting enterprises’ total factor productivity. Thirdly, the promotion effect of digital economy development on enterprises’ total factor productivity will be affected by industry, enterprise property right attribute and the region where the enterprise is located.
