中文摘要：

在综合几个重要门户网站和专业杂志提供的数据的基础之上，建立了评价城市互联网发展状况的指标体系，并对中国的地级及地级以上城市的互联网使用规模、发展水平和外向性程度进行了分析和归类。互联网的空间形态是复杂动力机制的结果，取决于城市特征和各种相关因素的综合作用。先进的信息和通讯技术在一定程度上加剧了城市差异，可能导致地区之间的空间极化趋势。

英文摘要：

This paper establishes an index system to evaluate the development of internet cities based on the data from some portal websites and professional journals and classifies the Chinese cities in internet development by three dimensions： size, development level and outward oriented degree, It holds that the layout of internet is driven by a complicated mechanism which is the integration of various urban factors and other correlative factors. It finds that sophisticated information and telecommunication technologies to some extent intensify the gap among cities which probably brings on the spatial polarization.
