摘要
在没有政府规制的情况下,进入退出机制使市场结构从竞争向集中转化,因为进入退出壁垒的存在可能使市场结构更倾向于不完全竞争。但是,产业组织理论表明,这些壁垒也并非不可逾越。然而、政府的准入规制则使得自然垄断演变为一种法定垄断,并形成一种超垄断的市场结构,从而改变对垄断行业进行市场结构调整和引入竞争的过程。中国电信业中的准入规制与市场结构的形成也证明了这一点。
Without access regulation by government, the entry and exit mechanism makes the market structure change from competition to centralization, because that the existence of entry and exit barriers may make the market structure tend to be incomplete competition. However, the industry organization theory shows that these barriers are not impassable. While the access regulation make the natural monopoly to be a statutory monopoly and a super-monopoly market structure is formed. Thus the process of adjusting the market structure and introducing competition to monopoly industry is changed. The access regulation and the formation of market structure of the telecommunication industries in China have proved this.
