Abstract: Based on ecological perspective, the concept of incubator niche was proposed, and the incubator niche evaluation index system was constructed from three dimensions:economic-technical-social resources. On this basis, the niche model was used to evaluate the development level, development coordination degree and development suitability of incubators in 18 cities of Guangdong Province. The results show that:(1) while incubators have significant spatial agglomeration characteristics, they have higher niche in developed regions; (2) the social resource niche of the incubators in Guangzhou and Zhuhai lags behind the economic and technical niche, and social resources are the key "ecological factors" for incubators in these two cities; the technical niche of incubators in Dongguan and Foshan is slightly insufficient, which should be strengthened in the future; with the development level of incubators in the eastern western and northern regions backward, all resources need to be excavated and developed; (3) incubators in Guangzhou have highest development suitability, and the incubators in eastern, western and northern regions have high evolutionary momentum.
