摘要
在系统梳理数字经济如何影响企业全要素生产率内在机理的基础上,以2010-2019年中国沪、深两市A股上市企业为样本,结合省级层面的宏观指标,运用双向固定效应模型和中介效应模型进行实证检验。结果表明:第一,数字经济发展能显著提高企业全要素生产率,且经过多种方法的稳健性检验后此结论仍然成立;第二,技术市场规模能作为数字经济影响企业全要素生产率的一条传导路径。进一步运用面板分位数模型检验发现,数字经济对企业全要素生产率的影响存在显著的结构性变化,即随着企业全要素生产率的提高,数字经济发展的边际影响递减。最后,基于研究结论提出加快发展数字经济、引导企业提高数字化转型能力、加强技术市场监管、对不同地区采取差异化的数字经济和技术市场发展战略等对策建议。
On the basis of systematically sorting out the internal influencing mechanism of the digital economy on enterprises’ total factor productivity,taking A-share listed enterprises in Shanghai and Shenzhen from 2010 to 2019 as samples and combining macro indicators at the provincial level,this article uses two-way fixed effect model and intermediary effect model to conduct empirical tests.The results show:first,the development of digital economy can significantly improve the total factor productivity of enterprises,and this conclusion is still valid after the robustness test of various methods;second,the scale of technology market can be used as a transmission path for digital economy to affect the total factor productivity of enterprises.Further quantile model analysis shows that the impact of digital economy on enterprise total factor productivity has significant structural changes,that is,with the increase of enterprise total factor productivity,the marginal impact of digital economy development decreases.Finally,based on the research conclusions,countermeasures and suggestions are put forward such as accelerating the development of digital economy,guiding enterprises to improve the digital transformation capacity,strengthening the supervision of technology market,and adopting differentiated digital economy and technology market development strategies for different regions.
