Because of the change of the environment, the cooperative nature is different on the supply chain. Not only there is competition between firms, but also between groups. Firms, which work together in the same supply chain for maximizing common profit, form a cooperative group to compete against another group. The competitive advantages of individual firm are connected with the group which it joints in. Therefore, it is the critical factors to integrate the members of cooperative network for creating and gaining the whole competitive advantages. To get those advantages is an important task for all of firms, especially by the firms which locate in a core position of the cooperative network. This research focuses on the impact of the management capabilities of central firm on the supply chain. We suggested that the capabilities of selecting/eliminating right partners, building cooperative cultures, sharing the profit fairly and creating the monitoring mechanism appropriately would effectively influence the level of supply chain integration.
