It is found that the digital economy can promote the promotion of urban innovation vitality, and this conclusion is still valid after replacing the robustness test of the explained variables. The further mechanism test shows that the upgrading of industrial structure is an important intermediary variable for the digital economy to enhance the dual-innovation vitality of cities, and the digital economy can promote the dual-innovation vitality of cities through the upgrading of industrial structure.
