As the development of supply chain management is an inevitable trend. VMI is acollaborative strategy between downstream enterprises and vendors. Compared withcollaborative model of the traditional supply chain, the cooperation between downstreamenterprise and vendors are deeper in VMI environment. As long as the good partnership isestablished, downstream firms and vendors can implement the integration and cooperationwell to achieve the win-win purpose.
