数字经济与全要素生产率--基于资源、技术与效率的中介效应

Digital Economy Promotes Total Factor Productivity--Theoretical Logic and Empirical Test

当前,数字经济已成为我国经济高质量发展的新动能,而经济高质量发展的一个重要体现就是全要素生产率的提高。文章以中国30个省域2013—2019年的面板数据为依据,使用综合指数评价法和随机前沿分析法对数字经济及全要素生产率进行了测度,并采用面板固定效应模型和中介效应模型对数字经济和全要素生产率关系及影响机制进行了研究。结果表明:(1)无论全国整体还是东中西部地区,数字经济对全要素生产率均具有正向作用,且对于中部地区的促进作用明显强于东西部地区。(2)创新能力和生产效率是数字经济促进全要素生产率的两个重要机制性因素,数字经济能够通过对两者的影响间接改变其自身对全要素生产率的促进作用。因此,地方政府应从提高技术水平和生产效率、实现数据共享等方面发展数字经济,以数字经济的高质量发展推动全要素生产率的提升。

Currently,the digital economy has become a new driving force for high-quality economic development,and an important manifestation of high-quality economic development is the improvement of total factor productivity.Based on the panel data of 30 Chinese provinces from 2013-2019,the article measures the digital economy and total factor productivity using the comprehen⁃sive index evaluation method and stochastic frontier analysis,and investigates the relationship and impact mechanism between the digital economy and total factor productivity using the panel fixed-effects model and the mediating-effects model.The results show that:(1)the digital economy has a positive effect on total factor productivity in both the whole country and the east,middle and west regions,and the promotion effect is significantly stronger for the central region than the east and west regions.(2)innovation capability and production efficiency are two important institutional factors for the digital economy to promote total factor productivi⁃ty,and the digital economy can indirectly change its own promotion effect on total factor productivity through the influence on both The digital economy can indirectly change its own role in promoting total factor productivity by influencing both.Therefore,local governments should develop the digital economy in terms of improving technology and production efficiency and realizing data shar⁃ing,so as to promote total factor productivity with the high-quality development of the digital economy.
