The relationship between economic organizations in the industrial cluster is similar to the relationship of species in ecological system, and symbiotic reciprocity, competition and cooperation are the basic. The ecological development is mainstream and direction of industrial cluster. In this paper, firstly, we studied the ecological symbiosis growth model of industry cluster, and tbund it being according to logistic growth model; secondly, we studied the growth and reproduction of economic organizations in industrial cluster in three different cases, which with only competition relations, only beneficial relations, and both competition and beneficial cooperation relationship between economic organizations, and finally, we determined the number of economical organizations when the industrial cluster attained ecological equilibrium.展开更多
