Based on the mediating effect of market integration， the impact of China's industrial intelligentized development on the urban?rural income gap has been investigated， with the application of industrial robots in manufacturing as an example. The empirical results show that the application of industrial robots helps narrow the urban?rural income gap and promotes coordinated urban?rural development， which remains valid after a series of robustness tests. Further research reveals that industrial intelligence reduces the urban?rural income gap by enhancing the integration of both commodity market and labor market. So the government is expected to promote urban?rural equity and reduce the urban?rural income gap by expanding the application of industrial robots， reducing local protectionism， and accelerating the integration of both commodity and labor markets.
