摘　　要：文章在生产-流通-消费框架下,在供零双边垄断这一纵向关系中考虑了所有权配置效应问题。发现所有权配置会对市场绩效或配置效率产生重大影响。均衡分析表明,无论所处哪一个环节,国有企业的存在具有内部化垄断外部性、减轻或消除双重加价、稳定市场均衡价格和销售量的作用。这一模型可为我国在改革开放初期,在流通领域保留部分国有企业,采用渐进式改革提供了一定的理论解释。当市场处于严重的不完全竞争,或生产-流通环节的某一端处于垄断状态时,适当地保留国有企业或对有关企业进行严格监管,有利于整体社会效益的提升和保障消费者的权益。文章从纵向生产和流通关系的角度,在一定程度上证实了我国经济转型过程中部分流通经济学家们曾经提出的"国有商业具有稳定市场作用"的观点。This paper reconsiders the ownership aUocation effect in bilateral monopoly under the production-circulation-consumption framework. We find that ownership has a significant impact on market performance or allocation efficiency. The equilibrium analysis shows that the presence of state-owned enterprises can internalize monopoly externalities, reduce or eliminate the double marginalization, and stabilize the market price and sales. The result provide a theoretical explanation why China at the beginning of reform and opening up in the circulation retained many state-owned enterprises and adopted progressive reform patterns. When the market is in serious imperfect competition, or some part of supply chain is in a monopoly state, reserving some state-owned enterprises or implementing strict supervision, can benefit the social welfare and protect the consumer interest. This paper also confirms some economist views that state-owned commercial enterprise can stabilize the market in China＇s economic transition process.
