The coupling coordination degree between human capital and AI in China has been increasing, indicating a growing trend of coordinated development between the two. This growth was particularly evident in 2013 and 2015, but has since entered a downturn phase starting in 2017. When considering regional disparities, all four regions have shown consistent upward trends in coordinated development. However, the eastern region has significantly outperformed the other regions, with its degree of coordinated development approximately 1.03 times higher than the rest in 2011. This discrepancy remains notable as of 2019.
