摘要
当前,数字经济已经成为驱动我国经济高质量发展的重要推动力。本文选用2009-2019年省际面板数据,在理论层面上分析数字经济发展对全要素生产率的影响机制,并基于合适工具变量克服内生性问题的基础上,通过实证分析,检验数字经济发展对区域全要素生产率的影响。研究发现:数字经济发展显著提高区域全要素生产率;研发投入强度是数字经济影响全要素生产率的重要渠道,发挥部分中介作用。
At present, the digital economy has become an important driving force for the high-quality development of my country’s economy. This paper selects provincial panel data from 2009 to 2019 to analyze the impact mechanism of digital economy development on total factor productivity at the theoretical level, and based on appropriate instrumental variables to overcome endogenous problems, through empirical analysis, to test the impact of digital economy development on regional impact on total factor productivity. The study found that the development of the digital economy significantly improves the regional total factor productivity;the R&D investment intensity is an important channel for the digital economy to affect the total factor productivity, and plays a partial intermediary role.
