摘　　要：在传统的垄断市场模拟中,存在一个前提假设,即市场参与者的产品是同质的,但这一假设存在局限性。围绕多产品完全垄断市场这一核心,建立理论模型,阐明了多产品完全垄断市场在技术限制条件下的均衡解,并以技术含量最高的微处理器产品为考察对象进行实际分析。研究认为,在技术限制条件下,即使完全垄断者也没有力量控制多产品的供给量。因此,在高科技市场中,反垄断的关键在于如何促进技术进步以及提高技术信息的共享程度。此外,对一些独特的市场现象从内在机制给出了解释。There is a assumption that each firm has a product that is at most slightly different in the classic theory of monopoly and oligopoly. This thesis breaks through this assumption and sets up a theoretical model on monopoly market of multi-product of different qualities. Furthermore, we derive an equilibrium solution under the condition of technology restraints and analyze the highest-technology market of the Central Processor Unit underlying this model. The research puts forward the conclusion that even the monopolists, with the technology restraints, are unable to control the quantity of multi-product market and the Antimonopoly policies should be taken for the high-tech market is to promote the advance of technology and ineent the sharing of technology information. Besides, this thesis applies the model to explain some unique phenomenon of this kind of market.
