数字经济提升制造业绿色全要素生产率了吗?

发布时间:2024-03-29作者:朱承亮 杨曼 李勃昕浏览次数:15

摘要:促进数字经济和实体经济深度融合是面向中国式现代化做出的重大战略抉择。本文以2012—2020年省级面板数据为样本,在运用熵值法测算数字经济发展水平,采用GML生产率指数测算制造业绿色全要素生产率的基础上,分析了数字经济对制造业绿色全要素生产率的影响。研究发现:数字经济能够显著促进制造业绿色全要素生产率提升,数字经济发展水平越高,其对制造业绿色全要素生产率的促进作用越大,这一结论具有稳健性;数字经济对制造业绿色全要素生产率的影响存在滞后效应,且随着滞后期数增加,数字经济的促进作用越大;数字经济对制造业绿色全要素生产率的影响存在区域异质性,数字经济能够显著提升东部、中部、南方地区制造业绿色全要素生产率,但对西部地区存在抑制作用,对北方地区影响不显著;数字经济通过提高市场化水平、促进技术创新、促进产业结构升级、提高数字化人力资本水平等渠道提升制造业绿色全要素生产率。建议从加快数字技术赋能、重视数字技术鸿沟、培养数字转型人才等方面加快制造业数字化转型升级

Has the Digital Economy Promoted the Green Total Factor Productivity of Manufacturing?

Abstract: Promoting the deep integration of the digital economy and substantial economy is a major strategic choice for Chinese path to modernization. Based on provincial panel data from 2012 to 2020, this paper uses entropy method to measure the development level of the digital economy, and uses GML productivity index to measure the green TFP of manufacturing industry. It analyzes the impact of digital economy on the green TFP of the manufacturing industry. The paper finds that the digital economy can significantly promote the improvement of green TFP of the manufacturing industry. The conclusion is robust, that is the higher the level of digital economy development, the greater its role in promoting the green TFP of the manufacturing industry. The impact of the digital economy on the green TFP of the manufacturing industry has a lag effect, and as the lag period increases, the promoting effect of the digital economy becomes greater. The impact of the digital economy on the green TFP of the manufacturing industry exhibits regional heterogeneity. The digital economy can significantly improve the green TFP of the manufacturing industry in the eastern, central, and southern regions, but it has a restraining effect on the western region and has no significant impact on the northern region. The digital economy enhances the green TFP of the manufacturing industry through channels such as improving marketization level, promoting technological innovation, promoting industrial structure upgrading, and improving the level of digital human capital. The paper suggests accelerating the digital transformation and upgrading of the manufacturing industry by accelerating the empowerment of digital technology, emphasizing the digital technology gap, and cultivating digital transformation talents.
