The results show that the niche width and overlap degree of the enterprise technology niche are in an inverted U-shaped relation with its innovation ability. The central niche of the system positively adjusts the relationship between the width of the enterprise's technology niche and the innovation ability, and negatively adjusts the relationship between the overlap degree of the enterprise's technology niche and the innovation ability. The depth of the central niche of the system negatively regulates the relationship between the width of the technology niche and the innovation capability of the enterprise, but has no significant influence on the relationship between the overlap degree of the technology niche and the innovation capability.
