The eastern region shows a stronger efficiency-enhancing effect in AI and human-AI cooperation. Developed cities in particular benefit from the coordinated development of AI and human capital, leading to even greater efficiency gains. This suggests that human-AI cooperation is more effective in developed regions and cities, possibly due to their earlier adoption and faster development of AI, along with higher levels of human capital and advanced economic and environmental conditions that enable better collaboration.
