It is of great significance to optimize the planning and layout of new energy power generation projects on the basis of fully comparing the competitiveness of various new energy power generation projects to promote the highquality development of the regional new energy industry. In order to scientifically measure the competitiveness of various new energy power generation projects in the region and analyze the competition pattern of regional new energy power generation projects, this paper constructs a model of niche width, intensity and overlap of regional new energy power generation projects based on the niche theory, and takes the western region of Inner Mongolia as an example, combined with the operation data of new energy power generation projects in 2022, to measure and analyze the ecological niche of wind power and solar power generation projects in each league city. The results show that there is a mismatch between the niche "structure" and the "scale" width of new energy power generation projects in the western region of Inner Mongolia, and it is necessary to continuously optimize the structure and scale of new energy installed capacity in Ulanqab and Bayannur City. The intensity of new energy niche in the "HohhotBaotouOrdosWuha" area is low, and the development of distributed new energy power generation projects should be considered in the future. The ecological niche overlap between Wuhai and other cities in the western region of Inner Mongolia is low, indicating that Wuhai area has strong potential for new energy development. The research results can provide theoretical support for regional new energy planning, and also provide a decisionmaking basis for the project development of energy investment enterprises.
