数字新质生产力与全球价值链嵌入:理论机制与实证检验

Digital New Quality Productive Forces and Global Value Chain Embedding:Theoretical Mechanism and Empirical Test

以中国2010~2022年41类产业面板数据为基础,通过构建动态面板、两步中介模型,实证分析数字新质生产力对全球价值链嵌入的影响效应与作用机制,研究发现,数字新质生产力对全球价值链嵌入具有正向促进效应,且该结论经过工具变量检验、替换测算方式及数据缩尾处理在内的稳健性检验后依然成立。异质性检验发现,数字新质生产力对第一产业全球价值链嵌入无显著作用,对第二产业、第三产业全球价值链嵌入具有直接促进效应;相比内陆地区,数字新质生产力对沿海地区全球价值链嵌入的推动作用更为显著。进一步的作用机制检验发现,产业结构升级、生产要素配置在数字新质生产力对全球价值链嵌入的影响中具有中介效应。根据上述结论,提出统筹数字“基建+服务”战略布局、构建数字“攻坚+超前”创新生态、重塑数字“城市+产业”联动网络、建立健全“贸易+产权”政策支持机制,为实现全球价值链深度嵌入提供新思路。

Based on the panel data of 41 types of industries in China from 2010 to 2022,this paper empirically analyzes the influential effect and mechanism of action of digital new quality productive forces on global value chain embedding by constructing a dynamic panel and a two-step mediation model.The results show that digital new quality productive forces have a positive promotion effect on global value chain embedding The heterogeneity test shows that digital new quality productive forces have no significant effect on global value chain embedding of the primary industry,but have a direct promotion effect on global value chain embedding of the secondary and tertiary industries.Digital new quality productive forces play a more significant role in promoting global value chain embedding on coastal areas than on inland areas.Further test of mechanism of action shows that the upgrading of industrial structure and the allocation of production factors have a mediation effect on the impact of digital new productive forces on global value chain embedding.
