先发优势与互联网互联互通阶段政策

分析两个互联网骨干网斯坦克尔伯格(Stackelberg)竞争和互联互通质量序贯均衡。对于前者,重点分析了企业利润、社会福利与互联互通质量的关系,得出骨干网间互联互通应该是有层次的、有所区别的,同时确保一定的互联互通质量是必要的;通过对后者的分析得出,在已有业务或用户间,骨干网网间若是高质量的互联互通,其在新业务或用户间必然也采取高质量的互联互通,同时也得出在互联网规模较小时,骨干网间将会选择较高的互联互通质量。

First-Mover Advantage and Interconnection between Internet Backbone Providers

The Stackelberg competition game and interconnection quality sequential equilibrium between two IBPs(IBPs: internet backbone providers) is studied to promote internet development and lay out reasonable interconnection policy.For the former,it emphasizes on the relationship between the corporation profit,social welfare and interconnection quality.It concludes that Interconnection between IBPs must be hierarchical and differential and interconnection quality to a certain extent is essential.For the latter,if Interconnection quality between the mature services or the old consumers is high,the IBPs must implement high interconnection quality between the new services or consumers.It also concludes that when the scale of internet is low,interconnection quality between IBPs must be high.
