Abstract: This research focuses on Internet hierarchy based on economic relationship among ASes，while considering node attribute distinction simultaneously.Consequently a model，which is quite similar to the real network both on global characters and local characters，is proposed.The modeling process is composed by two steps including confirming the hierarchy allocation and determining the link strategy，and its parameters are easily measurable.This model could represent a reasonable framework for further research on Internet topology modeling.

Key words: Internet, economic relationship, modeling, hierarchy

摘要： 在区分节点属性的基础上，基于自治系统级互联网拓扑中存在的经济关系对网络进行层次划分，从而构建出在全局和局部范围内都与实际网络数据极为相似的模型。该模型采用先确定层次归属、再确定连边策略的分步建模过程，不仅实现了模型参数的可测量，而且为互联网拓扑建模研究的进一步发展构建出一个较为合理的模型框架。
