Using the panel data of 29 provinces in China from 2015 to 2018, this paper analyzes the impact of the internet, technological innovation, and their interaction on high-quality economic development. As the results show, the internet and technological innovation promote economic growth efficiency, economic growth stability, industrial structure optimization, and sustainable development level, where technological innovation promotes more significantly but hinders the economic welfare level to some extent; the interaction between the internet and technological innovation has a significant positive correlation with high-quality economic development and strengthens the promotion of technological innovation on high-quality economic development; human capital plays a significant role in promoting all aspects of high-quality economic development, while fiscal expenditure has no significant impact on high quality economic development. therefore, the internet should be leveraged to drive technological innovation capacity, and better play the guiding role of the government.
