Abstract: At present, China's urbanization process is at an important stage from "scale expansion" to "quality improvement". Using panel data from 31 provinces in China from 2004 to 2019, a PVAR model covering the advancement of human capital, the agglomeration of high-tech industries, and the improvement of urbanization quality was constructed, and the dynamic interaction between the three was empirically analyzed. The results show that the lagging stage of human capital advancement has an impact coefficient of 0.198 at the 10% significance level. The advancement of human capital advancement mainly relies on its own inertia, and the agglomeration of high-tech industries has the least impact on it. The improvement of the quality of urbanization is an important factor in promoting advancement of human capital. The advancement of human capital and the agglomeration of high-tech industries are Granger causality, and the advancement of human capital and the improvement of the quality of urbanization both have a positive effect on the agglomeration of high-tech industries. The advancement of human capital is conducive to improving the quality of urbanization, but the long-term effects need to be strengthened. The role of the agglomeration of high-tech industries in promoting the improvement of urbanization quality needs to be strengthened.
