Researches On Co-Opetition Strategies Between Oligopoly Supply Chain Enterprises

With the deepening of the global economic integration development, the sharpening of market competition and the worsening of the enterprises management environment, the co-opetitive quasi-market network organization has been becoming an important way for more and more business enterprises to make reasonable use of resources mutually and enhance oneself competitive ability efficiently. So the co-opetitive supply chain, as an important style of the co-opetitive quasi-market network organization, has become a hot point which entrepreneurs and experts in the world pay close attention to and research on.This paper used quantitative analysis methods to deepen the research on co-opetition between supply chain enterprises by answering a series of problems, such as, on what condition should a business enterprise adopt a supply chain strategy, and based on what rational attitude should the business enterprise select itself behaviors when it adopt a supply chain strategy, and what was the whole connotation of supply chain co-opetition, and what was a real supply chain co-opetitive strategy, etc.Firstly, based on analyzing a great quantity of literatures and the current practices of industrial supply chain construction and integration in china, we raised a three-dimensional research framework of supply chain management, of which the three dimensions were supply chain strategy management dimension, supply chain operation management dimension and supply chain integration orientation dimension. According to this framework, we pointed out and analyzed the shortcomings in the current practices of supply chain integration and co-opetition, made clear the focal point, the train of thoughts and the research framework of this paper.Secondly, based on linear demand-price function, we built up different models of manufacturer-retailer supply chain in identical market or differential market, compared each equilibrium index of vertically-integrated enterprises with the corresponding index of supply chain enterprises, and studied the condition on which the business enterprise should adopt "the supply chain strategy" . As a result, we acquired the different boundary conditions of supply chain strategy in identical market or differential market.Thirdly, by building up a series of dynamic game models, we quantitatively analyzed the difference of efficiency(i.e. the total profits of all business enterprise in supply chain) of supply chains with different combination of rational attitude, made clear that the "noncooperative-noncooperative" relation was only a basic contract relation between business enterprise but not the essence of the supply chain co-opetition, and proved that only the "cooperative-noncooperative + distribute profits reasonablely" strategy combination was a real co-opetition strategy of supply chain. Based on above quantitative analysis, we raise a more perfect connotation of supply chain co-opetition.Finally, we researched an operational problem that supply chain enterprises cooperatively invest in R&D of upper stream enterprise in identical market or differential market. On the one hand, we revealed the necessary that the upper stream enterprise and the lower stream enterprise must invest R&D together. On the other hand, we proved the argument in the supply chain operation level that the "cooperative-noncooperative + distribute profits reasonablely" strategy of supply chain co-opetition was an important way to carry out supply chain integration.
