As the 1990s into the globalization of the world economy, the information age, the rapid development of technology, diversification of customer needs, as well as the scarcity of resources together constitute the modern enterprise dynamic operating environment. In this thesis, different supply chain structure as research background, from information sharing among enterprises portrait / landscape view of competition and cooperation, information sharing, respectively vertical and horizontal cooperation (transport) as well as a competitive supply chain optimal supply chain members operational strategies of the system, in-depth discussion, thereby further enriching the research in the field of supply chain management. First, this thesis competition in the supply chain without transverse vertical information sharing constructs manufacturer retailer private demand information how to obtain the information sharing model, demonstrated that in the case of asymmetric demand information wholesale price contracts and two contract pricing ability to achieve vertical information sharing depends on the retailer's retained profits. When two contract pricing information sharing can be achieved when we find one to achieve separation of transfer payments equilibrium value interval, and found in the equilibrium manufacturers and retailers the optimal decision-making and information symmetry the same situation. Secondly, this paper discusses the competitive landscape in the vertical supply chain information sharing. We constructed by one by capacity constraints for manufacturers and multiple retailers Cournot competition information sharing model. By solving the various members of the supply chain optimal decision, we find that when the total demand is greater than capacity, when manufacturers discrimination through capacity allocation strategy can promote information sharing needs of the parties longitudinally on a voluntary basis to achieve, and gives information to achieve discriminatory allocation of shared capacity lower bound parameters; addition, the results show production capacity constraints will limit the manufacturer's profits, while social welfare and consumer surplus production capacity are limited. Again, this thesis horizontal cooperation between enterprises build strategies for the supply chain transport model among retailers. We discuss a centralized and decentralized decision-making under the manufacturer's optimal wholesale prices and retailers optimal order decision making and found that the upstream manufacturers' pricing behavior into the scope of the study after the transfer even though it can improve supply chain performance, but can not fully collaborative supply chain interests of all parties, which decentralized decision-making when the optimal order quantity can not achieve the optimal level of centralized decision-making time. In the study completed the vertical and horizontal cooperation after the end of the paper discusses the competitive supply chain action sequence for optimal decision of each member as well as the impact of supply chain performance. We examined two competing parallel distribution systems, respectively, in deterministic and stochastic demand needs to solve the case of the optimal decision channel members and found that no matter what state the demand, there is always between channels after mover advantage, while Each channel exists within the first-mover advantage; But first-mover advantage within the channel as demand increased uncertainty and to obtain first-mover advantage members enhanced risk aversion weakened.
