Abstract: In order to explore the influence mechanism of real leadership on miners’ safety innovation behavior under the background of intelligence, coal mine enterprises can maintain a safe production environment under the dynamic change environment. By constructing a cross-level model among authentic leadership, knowledge sharing, job engagement and safety innovation, a total of 264 miners from 30 coal mine shift groups were taken as the research object to carry out cross-level research. The results show that authentic leadership positively regulates the safety innovation of miners; miners’ job involvement plays a cross-level mediating role between authentic leadership and miners’ safety innovation. Knowledge sharing between teams plays a cross-level mediating role between authentic leadership and miners’ safety innovation. Knowledge sharing among teams positively moderates miners’ work involvement; inter-team knowledge sharing and miners’ work involvement play a cross-level chain mediating role between authentic leadership and miners’ safety innovation.
