IP长话运营商通过口头协商或签署协议控制价格形成价格联盟,这是由寡头垄断的市场属性决定的,是替代品带来的挤兑效应和价格战导致的降价效应引起行业性危机的表现。这种行为在法律上存在违归倾向,在经济上为负效应,既损害了消费者利益,又降低了市场配置资源的效率。 IP long-haul operators form price alliances by verbally negotiating or signing agreements to control prices, which is determined by oligopolistic market attributes, the result of the industry crisis caused by the run-off effect of alternatives and by the price-cutting effects of price war. This kind of behavior has the trend of returning to law in law and is economically negative. It not only harms the interests of consumers but also reduces the efficiency of market allocation of resources.
