Abstract: Based on the dual perspectives of "Amount" and "Quality" of the manufacturing industry, this paper examines the impact of intelligent manufacturing on the high-quality development of the manufacturing industry and its regional differences from both theoretical and empirical perspectives, and explores the mediating effect of science and technology innovation in the impact of intelligent manufacturing on the high-quality development of the manufacturing industry, while further exploring the regional heterogeneity of this mediating effect.The results show that: (1) Intelligent manufacturing can promotesimultaneously the "Amount and Quality" of the manufacturing industry and thus achieve high-quality development of the manufacturing industry, and the promotion effect of intelligent manufacturing on the "Amount" of the manufacturing industry is greater than the "Quality".(2) Intelligent manufacturing has contributed to the high-quality development of the manufacturing industry in the east, central and western regions, but there are regional differences in the way it works. In the eastern and western regions, the role of intelligent manufacturing in enhancing the high-quality development of manufacturing is mainly through promoting simultaneouslythe "Amount and Quality" of manufacturing, while the central region promotes the reasonable growth of manufacturing"Amount".(3) There is a partial mediating effect of Science and technology innovation in the "Amount" of smart manufacturing on manufacturing industry, and the mediating effect is not significant at the "Quality" level; from a sub-regional perspective, Science and technology innovation has a partial mediating effect at the " Amount " level in the East and Central regions, a complete mediating effect at the " Quality " level in the East region, and a non-significant mediating effect at the " Quality " level in the Central region; and there is a partial mediating effect of Science and technology innovation at the " Quality " level in the West region, and a non-significant mediating effect at the " Amount " level.The findings of this paper provide useful insights for promoting the deep integration of artificial intelligence and manufacturing industry, and thus promoting the high-quality development of manufacturing industries.

摘要： 基于制造业“量”与“质”的双重视角，本文从理论和实证的角度考察智能制造对制造业高质量发展的影响及其区域差异，并探究科技创新在智能制造对制造业高质量发展影响中产生的中介效应，同时进一步探讨了这种中介效应存在的区域异质性。结果显示：（1）智能制造能够通过促进制造业“量质齐升”进而实现制造业高质量发展，且智能制造对制造业“量”的促进作用大于“质”。（2）智能制造对东中西部各区域制造业高质量发展均表现出促进作用，但其作用途径存在区域差异。其中，东部和西部地区智能制造对制造业高质量发展的提升作用主要通过推进制造业“量质齐升”，而中部地区则是通过促进制造业“量”的合理增长。（3）科技创新在智能制造对制造业高质量发展和制造业“量”的影响中存在部分中介效应，在“质”层面的中介效应不显著；分区域来看，科技创新在东中部地区“量”层面均具有部分中介效应，且在东部地区“质”层面具有完全中介效应，在中部地区“质”层面中介效应则不显著，而在西部地区“质”层面存在部分中介效应，在“量”层面中介效应则不显著。本文的研究结论为推进人工智能与制造业深度融合，进而推动制造业高质量发展提供了有益启示。
