Abstract Based on the theory of similarity,this paper links the several hypothesis of species coexistence in ecology with the actual development status of industry economy.The coexistence mechanisms of industry populations are mainly discussed by small spatial scale:the latent species pool coexistence mechanism of in a specifical temporal and spatial scope; the coexistence mechanisms under the conditon of niche regeneration caused by competitivity; the coexistence mechanisms under the conditon of the formation of adaptive temporary niche caused by similar competitive capability;the pre-occupied and lottery coexistence mechanisms under the conditon of the faultage of resourses; the coexistence mechanisms through transfer and diffuseness in the heterogeneity survival environment.
