本文通过构建一个二阶段博弈模型,分析了不同互联模式下非对称互联网骨干网网间互联质量决策问题。分析结果表明,骨干网的初始用户规模差异影响非对称骨干网网间互联质量的选择。当初始用户规模差异较小时,不管是在直联还是转接互联下,主导骨干网和弱势骨干网都有激励提高网间互联质量；当初始用户规模差异较大时,弱势骨干网偏好于提高互联质量,但主导骨干网在直联下通常选择降低互联质量,而在转接互联下,主导骨干网则有动力提高互联质量。并且,不管是以直联还是以转接的方式进行骨干网网间互联,消费者剩余都随着互联质量的提高而增加。根据研究结论,并结合中国实际,本文有针对性地提出了提升我国互联网骨干网网间互联质量的建议,以促进我国互联网产业在网络强国战略背景下健康快速发展。

By constructing a two-stage game model , this paper analyzes the interconnection quality decision of asymmetric internet backbone network under different interconnection modes. The results show that the initial user size difference of the backbone affects the selection of the interconnection quality of the asymmetric backbone. When the initial user size difference is small, whether by private peering or transit, the dominant backbone and the weak backbone have incentives to improve the interconnection quality; when the initial user size difference is large, the weak backbone prefers to improve interconnection quality, but the dominant backbone usually reduces the interconnection quality by private peering ,and improves the interconnection quality by transit.When backbones interconnect by private peering or transit, consumer surplus increases with the interconnection quality improved. According to the analysis conclusion and the Chinese reality, this paper puts forward some suggestions to improve the interconnection quality of internet backbone in China, so as to promote the healthy and rapid development of China"s internet industry under network power strategy.
