Abstract: The analysis results of this paper show that whether the upstream market is monopolized or there are the competitions of multiple backbone networks, the network investment amount and the social welfare under the interconnectionless settlement regulation are greater than that under the Internet settlement regulation. In order to promote the network investment in the backbone network market, this paper proposes that the regulating role of market mechanism in the interconnection settlement should be fully utilized. At the same time, the competition mechanism should be introduced in the upstream market to allow new competitors to participate in the competition.
