Abstract: Abstract The innovative city buildup is an essential strategy for implementing innovation-driven development and plays a supporting role in building a national innovation system. There remains no conclusive evidence on how cooperation between innovative cities affects cities’ innovation efficiency. Therefore, this paper investigates the effects of the innovative city cooperation network on cities’ innovation efficiency. The study uses a sample of 78 innovative cities in China from 2012 to 2019 to test the influence mechanisms of cooperation networks on cities’ innovation efficiency. The results indicated spatial heterogeneity in innovative cities’ innovation output efficiency and innovation transformation efficiency. The influence of connection width and connection depth on the innovation output efficiency and innovation transformation efficiency of cities shows an inverted U-shaped. The support for urban innovation mediates the effect of the connection width and depth on the cities’ innovation transformation efficiency. Therefore, we conclude that innovative cities are best served by maintaining a moderate connection width and depth in cooperation networks to enhance the cities’ innovation dual efficiency. The improvement of the support for urban innovation helps to promote the transformation of innovation achievements.
