With the enormous growth of globalized fund, supply chain, marketing and network technology, they make the rapidity of product circulation and manufactures on the supply chain display Co-opetition (Competition & Cooperation) phenomenon. However, Co-opetition demonstrates that the coordination strategy and standard contract are very important. We apply third contract types - basic contract, joint investment contract and profit shared contract to construct a supply economic system which proposed by Corbett et al.(2001). Under the information sharing and the specific function, this economic system carries different cooperation contract policy by the comparison static. Simultaneously, the numerical analysis proves the results of the comparison static and provides the consultation for the vertical cooperation manufactures in the supply chain system.
