A study on innovative evolution relationship based on ecological niche in supply chain cluster

The innovative evolution and development of supply chain cluster depend not only on the cluster competence itself but also on the participants\´ evolution behavior; the "ecostate" and "ecorole" of innovation of supply chain cluster determine different positions of firms in competition, cooperation and symbiosis, and reflect innovative coordination among members and influence of industry dynamic characteristics. Based on ecological niche Models, this paper reinterprets the "ecostate" and "ecorole" of innovation in a supply chain cluster under the ecostate-ecorole theory, and study the interaction mechanism of ecostate and ecorole in supply chain cluster from the supply chain cluster and environment. Finally, the coordination and innovative evolution mechanism are analyzed by using the diamond model.
