数字经济对制造业绿色转型升级的影响研究

Investigation into the Effect of the Digital Economy on the Green Revolution and Enhancement of the Manufacturing Sector

通过对2011~2020年全国30个省份的面板数据研究,本文构筑出一套完整的制造业绿色发展和数字化发展的评价指标体系,进而进行实证研究,探讨了数字化发展如何推动制造业的绿色转型和升级。本文的结果表明:总体上,我国数字经济对制造业绿色转型升级有显著正向作用;异质性检验表明,东、西部地区数字经济均可明显促进制造业绿色转型升级,而中部地区影响不显著;作用机制检验表明,数字经济可以通过提升创新水平来促进制造业绿色转型升级。本文依据实证分析结果,给予了相关的政策性建议,政府应采取相应政策来推动我国制造业企业数字化转型、充分发挥数字化新技术和创新水平的中介作用、加大绿色技术研发投入,为制造业绿色转型升级提供更好的平台。

This paper empirically tests the effect of the digital economy on the green transformation and upgrading of China’s manufacturing industry, as established by an index system based on the panel data analysis of 30 provinces and cities from 2011 to 2020. This paper’s findings demonstrate that, in general, China’s digital economy has a noteworthy beneficial influence on the green transformation and upgrading of the manufacturing sector;heterogeneity testing reveals that the digital economy in the eastern and western regions can evidently foster the green transformation and upgrading of the manufacturing industry, yet the central region’s effect is not noteworthy. The empirical analysis of the mechanism test reveals that the digital economy can foster a green transformation and an upgrade of manufacturing industry by augmenting the level of innovation. This paper then provides pertinent policy proposals. The government should implement policies to foster digital transformation in Chinese manufacturing firms, fully embrace the intermediary role of digital new technology and innovation, and augment investment in green technology research and development to create a more advantageous platform for the green transformation and upgrading of the manufacturing sector.
