数字经济对实体经济的影响——基于面板门槛效应的实证分析
The Impact of Digital Economy on the Real Economy—Empirical Analysis Based on Panel Threshold Effect

本文基于我国2013~2020年31个省(区市)的面板数据，构建数字经济发展评价指标体系，在理论分析的基础上，实证研究数字经济对实体经济的影响。实证发现：数字经济的发展显著提升了我国实体经济发展水平；在数字经济影响实体经济的过程中，当创新投入水平、创新产出水平和经济发展水平跨越门槛值时，数字经济对实体经济的促进作用显著增强，存在边际递增效应，为此，本文讨论了相关的对策建议，以期为数字经济与实体经济融合发展的政策制定提供有益思路。
Based on the panel data of 31 provinces (autonomous regions and municipalities) in China from 2013 to 2020, this paper constructs the evaluation index system of digital economy development, and empirically studies the impact of digital economy on the real economy on the basis of theoretical analysis. Empirical findings: The development of digital economy has significantly improved the development of our real economy; in the process of the digital economy’s influence on the real economy, when the level of innovation input, innovation output and economic development crosses the threshold value, the promotion effect of the digital economy on the real economy is significantly enhanced, and there is a marginal increasing effect. Therefore, this paper discusses relevant countermeasures and suggestions, hoping to provide useful ideas for the policy formulation of the integrated development of the digital economy and the real economy.
