摘 要:我国对具有"自然垄断"特征的电信行业进行规制,限制民营资本进入,由少数几家国有企业垄断经营,并通过纵向一体化模式垄断了"网络传输"和"服务供给"两个产业。然而,真正具有"自然垄断"特性的是电信行业的"网络传输"产业,"服务供给"并不具有"自然垄断"特性。通过古诺模型和斯塔克尔伯格模型的分析表明:政府可以放开对"服务供给"产业的规制,有效引入竞争,以促进资源的合理配置。有效的市场进入会分担在位企业已投入的固定成本,当在位企业的利润超过自然垄断阶段的利润时,在位企业有动机支持进入者进入。Our country regulates the telecommunications industry with the characteristic of natural monopoly, restricts private capital to enter. The telecommunications industry is operated by a few state-owned monopoly enterprises, which monopolize the network transmission and service delivery by the vertical integration model. However, the network transmission of the telecommunications industry has the natural monopoly characteristics, service delivery does not have. The results show that the government can liberalize regulation of the service delivery and introduce competition effectively by analyzing the Cournot model and Stackelberg models, so that the rational allocation of resources can be promoted. Effective market access will dilute the fixed costs of incumbent firms which have invested and they have an incentive to let entrants to enter, when the profit exceeds the profit of the monopoly stage.
