摘　　要：文章主要讨论的是企业专利后期产品质量的选择问题。文章分析表明,在给定企业原有产品品种质量不变的情况,如果企业再生产一种更高质量的产品,则企业可以增加其利润。但是,如果企业生产一种更低质量的产品,则并不能增加其利润。所以,如果企业多元化生产的是一种更低质量的产品,由于这不符合其利润最大化原则,所以它极有可能是为了垄断市场而进行的一种沉没成本投资,从而为其他厂商的进入设置进入壁垒。This article mainly discusses the choice of product quality in the late period of enterprise patent. This analysis shows that, given the variety and quality of the original products unchanged, if the enterprise produces a higher quality product, the enterprise can increase its profit. However, if the quality is lower, it does not increase its profits. So, in the late period of enterprise patent, if the enterprise diversification produces lower quality products, which is inconsistent with the principle of profit maximization, it is most likely a sunk cost investment for monopoly in the market, so as to set barriers to entry into the market for others.

关 键 词：产品质量 垄断市场 利润最大化
