数字化投入对制造业全球价值链分工地位的影响研究

The Impact of Digital Input on Manufacturing’s Position in the Global Value Chain

摘要: 本文基于2007~2020年世界42个国家的面板数据，通过固定效应模型、中介效应模型探究数字化投入对制造业全球价值链分工地位的影响。研究发现，数字化投入能够显著提升制造业全球价值链分工地位；同时，数字化投入通过提高技术创新能力、贸易开放度并促进出口产品结构优化，进一步提升制造业全球价值链分工地位；此外，数字化投入对制造业全球价值链分工地位的影响还存在基于国家收入水平及行业要素禀赋的异质性。在此基础上，文章提出相关政策建议，以期为制造业提升全球价值链分工地位提供理论依据和政策参考。

Abstract: Based on the panel data of 42 countries in the world from 2007 to 2020, this paper explores the impact of digital input on the division of labor in the global value chain of manufacturing through the fixed effect model and the intermediary effect model. The findings indicate that digital input significantly enhances the division of labor position of manufacturing in the GVC. Furthermore, digital input improves this position by strengthening technological innovation, increasing trade openness, and optimizing the export product structure. Additionally, the impact of digital input on manufacturing’s GVC position exhibits heterogeneity based on national income levels and industry factor endowments. Based on these findings, the paper provides relevant policy recommendations to offer theoretical and policy insights for enhancing the manufacturing sector’s position in the global value chain.
