Abstract: Giving full play to the supporting role of green technology innovation is the key to accelerating the establishment of green low-carbon circular development economy system. This article regards the intelligent manufacturing pilot and demonstration project as a quasi-natural experiment and takes the listed manufacturing companies of A-share in China from 2010 to 2021 as the research object. Its main purpose is to empirically test the impact of intelligent manufacturing on green technology innovation by using Difference-in-Difference model. The study finds that intelligent manufacturing can promote green technology innovation and technology integration plays the mediating role in the relationship between intelligent manufacturing and green technology innovation. In terms of heterogeneity analysis, the effect of intelligent manufacturing is more significant in high-level and high-difficulty green technology innovation activities, independent innovation activities and the innovation activities in front-end production processes. And the positive effects of intelligent manufacturing on green technology innovation are more pronounced for enterprises that are larger, capital-intensive, and located in east area. The research conclusion of this paper provides theoretical implications for improving enterprise green technology innovation and promoting the upgrading and high-quality development of the manufacturing industry.
Keywords: Intelligent Manufacturing; Green Technology Innovation; Technology Integration
