摘　　要：在深入分析了数字经济对制造业技术创新的直接作用机制后,考察了知识溢出在数字经济促进制造业技术创新过程中的中介机制,并对2013—2023年间中国省域面板数据进行了实证检验。研究发现,2013年以来,中国制造业技术创新水平和数字经济的知识溢出水平基本处于匀速上升状态,数字经济发展水平在2018—2020年间的上升速度明显;数字经济对制造业技术创新存在显著的正向直接促进作用;知识溢出在数字经济促进制造业技术创新过程中存在显著的正向中介作用,中介作用力的发挥呈现倒“U型”特征。After the in-depth analyzing of the direct mechanism of the digital economy on manufacturing technology innovation,the mediating mechanism of knowledge spillover in the process of promoting manufacturing technology innovation in the digital economy is examined,and empirical tests are conducted using panel data of Chinese provinces from 2013 to 2023.Research finds that since 2013,the level of technological innovation in China's manufacturing industry and the knowledge spillover level of the digital economy have been steadily increasing,while the development level of the digital economy has shown a significant increase from 2018 to 2020.The digital economy has a significant positive and direct promoting effect on technological innovation in the manufacturing industry.There is a significant positive mediating effect of knowledge spillover in the process of promoting manufacturing technology innovation in the digital economy,and the mediating force exhibits an inverted U-shaped feature.
