Abstract：Digital economy plays a vital role in promoting the transformation of coal mining and selection industry to green and low-carbon development.In-depth analysis of the influence mechanism of digital economy on the carbon emission intensity of coal mining and selection industry can provide a path for the low-carbon and green development of China's coal mining and selection industry.This study uses the entropy method to calculate the digital economy development indicators of 25 provinces in China from 2011 to 2022,and uses the fixed effect model,mediating effect model and threshold effect model to explore the impact of digital economy on the carbon emission intensity of coal mining and selection industry and its mechanism.The results show that the development of digital economy significantly inhibits the carbon emission intensity of coal mining and selection industry,and this conclusion is still stable after eliminating some samples and various robustness tests such as endogenous tests.Compared with the western regions,the effect of digital economy on carbon emission reduction of coal mining and selection industry in the central and eastern regions is more significant;Compared with resource-based regions,the development of digital economy in non-resource-based regions has a more significant effect on carbon emission reduction in coal mining and selection industries.In the regions with a higher degree of opening to the outside world,the inhibitory effect of digital economy on the carbon emission intensity of coal mining and selection industry is more significant.Scientific and technological innovation and industrial structure upgrading are two important paths for digital economy to achieve carbon emission reduction in coal mining and selection industry.This study not only enriches the theoretical and empirical research in the field of digital economy and carbon emissions,but also has great significance in promoting the green transformation of coal mining and selection industry and achieving carbon emission reduction targets.
