Abstract: Inner Mongolia has a vast territory, bordering Gansu in the west and Russia in the east, with a straight-line distance of more than 2 400 kilometers from east to west. As a province on the border of northern China and one of the major industrial provinces, regional differences and historical backgrounds have resulted in obvious differences in the architectural styles of industrial heritage in the eastern and western regions. The paper adopted research methods such as field investigation and literature review, selected some representative industrial architectural heritages in eastern and central and western Inner Mongolia, and conducted a comparative analysis of the architectural structure and craftsmanship, and decorative arts of the industrial heritage in Inner Mongolia, and presented the industrial heritage of Inner Mongolia. The richness and diversity of industrial heritage provide a realistic basis for the overall protection strategy of regional industrial heritage.
