Investment in new infrastructure facilitates green transformation of industries and promotes green economic and social development. Using panel data of provinces from 2013 to 2022, a comprehensive evaluation system of new infrastructure and green transformation of industries was constructed. Based on the coupling coordination degree model, the results indicate that the development levels of new infrastructure and green transformation of industries have steadily increased during the research period, with the coupling and coordination degree gradually evolving towards a coordinated state. The development of the new infrastructure and green transformation of industries exhibits significant regional differences, with outstanding performance in the east and lower comprehensive development in the central, western and northeastern regions. While the level of green transformation in most resource-based regions has improved, they are still lagging behind the national average level. Overall, the coupling coordination level displays a pattern of high in the east and low in the west.
