Abstract Based on China’s prefecture and city-level data from 2011 to 2017, this paper uses a Threshold Model to explore the relationship between the scale of urban investment debt and the three levels of urban technological innovation (corporate technological innovation capacity, government’s ability to promote technological innovation and infrastructure environmental innovation). The study shows that there is an “invertedU-shaped” relationship between the scale of urban investment debt and the company’s technological innovation capabilities, and a “positive U-shaped” relationship with the government’s ability to promote technological innovation and infrastructure environmental innovation. The threshold for the scale of urban investment debt to promote urban technological innovation capabilities is from 0.2% to 2.9%. The relationship among the scale of urban investment debt in the eastern, central and western regions of China , the technological innovation capabilities of enterprises, the government’s ability to promote technological innovation and the ability of infrastructure environmental innovation is heterogeneous. Therefore, local governments need to issue urban investment bonds based on their own development in order to enhance the city’s technological innovation capabilities and prevent and control urban investment debt risks.
