数字经济视角下制造业全球价值链升级研究

Research on the Upgrading of Manufacturing Global Value Chain from the Perspective of Digital Economy

随着数字经济的快速发展,互联网技术渗透到传统经济领域,对制造业价值链升级产生重要影响。对数字经济影响制造业价值链升级的理论机理进行阐述,并进一步构建计量模型进行检验发现:数字经济对制造业全球价值链升级有显著的促进作用,稳健性检验结果依然支持上述结论;分行业看,数字经济对技术密集型和资本密集型制造业的影响更为突出。分地区看,数字经济对发达国家制造业价值链升级的促进作用更强;从影响机制来看,数字经济通过技术进步和劳动生产率提高促进制造业价值链升级。因此,实现中国制造业价值链升级要加强数字基础设施的建设,掌握数字经济的核心技术,重视人才培训,提高劳动的质量和水平。

With the rapid development of the digital economy,Internet technology has penetrated into the traditional economic field and has an important impact on the upgrading of the manufacturing value chain.In view of this,the theoretical mechanism of the digital economy affecting the upgrading of the manufacturing value chain is expounded,and an econometric model is further constructed to test.The study found that the digital economy has a significant role in promoting the upgrading of the global value chain of the manufacturing industry,and the results of the robustness test still support the above conclusions;in terms of industries,the impact of the digital economy on technology-intensive and capital-intensive manufacturing is more prominent.From the perspective of different regions,the digital economy has a stronger role in promoting the upgrading of the manufacturing value chain in developed countries;from the perspective of the impact mechanism,the digital economy promotes the upgrading of the manufacturing value chain through technological progress and labor productivity improvement.Therefore,it is necessary to strengthen the construction of digital infrastructure,master the core technologies of the digital economy,attach importance to personnel training,and improve the quality and level of labor in order to realize the upgrading of China's manufacturing value chain.
