The global economic situation is in a downturn, and the upgrading of manufacturing structure is a necessary transformation path for the manufacturing industry to achieve high-speed and stable development. The article analyzes the theoretical mechanism of the digital economy affecting the upgrading of manufacturing structure through the endogenous economic growth model, constructs a three-stage mediation effect model, and empirically researches the path of the digital economy affecting the upgrading of manufacturing structure in the Pearl River Delta. The study finds that the digital economy has a significant positive promoting effect on the upgrading of manufacturing structure. In terms of the influencing mechanism, the enhancement of the level of independent innovation and the advancement of the human capital structure are the important paths of the digital economy in promoting the upgrading of manufacturing structure. Among them, the mediating effect is 17.5% for the level of independent innovation and 17.4% for the level of the advancement of the human capital structure. The results of the study also found that the upgrading of manufacturing structure cannot be separated from government support, and the influence of government support on t the upgrading of manufacturing structure reaches 44.9%, and government deployment and control is conducive to accelerating the process of advanced manufacturing structure.
全球经济形势处于低迷状态，制造业结构升级是制造业实现高速稳定发展的必然转型路径。本文通过内生经济增长模型分析了数字经济影响制造业结构升级的理论机制，构建了三阶段中介效应模型，并实证研究了数字经济影响珠三角制造业结构升级的路径。研究发现，数字经济对制造业结构升级具有显著的正向促进作用。在影响机制方面，自主创新水平的提高和人力资本结构的提升是数字经济推动制造业结构升级的重要途径。其中，自主创新水平的中介效应为 17.5%，人力资本结构提升的中介效应为 17.4%。研究结果还发现，制造业结构升级离不开政府支持，政府支持对制造业结构升级的影响达到 44.9%，政府的部署和调控有利于加速先进制造业结构的进程。
