From the perspective of science and technology innovation, the research path of "science and technology innovationindustrial structure upgrading-common prosperity" is established. The intermediary effect model is used to explore the internal relationship between science and technology innovation and common prosperity and the path mechanism of industrial structure upgrading in the process of science and technology innovation promoting common prosperity. The following conclusions are drawn: (1) the common prosperity degree of Zhejiang Province increases with the improvement of scientific and technological innovation level; (2) industrial structure upgrading in Zhejiang Province not only has a positive impact on common prosperity, but also plays an intermediary role in the process of scientific and technological innovation promoting common prosperity, showing the transmission path of "scientific and technological innovation-industrial structure upgrading-common prosperity"; The mediating effect between industrial structure upgrading and technological innovation and common prosperity is 5.7%; (3) the level of government participation is an important factor affecting common prosperity. Based on the above conclusions, it is believed that we should attach great importance to and give full play to the leading role of scientific and technological innovation in the process of achieving common prosperity, and maximize the effect of scientific and technological innovation in promoting common prosperity through the intermediary role of industrial structure upgrading. Meanwhile, it is emphasized that we should give better play to the regulatory role of government intervention.
