本文将中国互联网域名地区分布数据与图形数据结合， 运用相关分析、Lorenz 曲线和区位 熵等方法， 从时间和空间上探讨了中国互联网分布的区域差异。通过分析认为: (1) 中国互联网发 展水平从东到西呈阶梯状分布。(2) 发展水平高的区域与发展水平低的区域差距较大。(3) 东部地 区和中部、西部地区的发展水平在拉大， 但全国各地区差异基本保持不变。(4) 东部地区互联网发 展速度加快， 中部地区发展缓慢， 西部地区步履艰难。(5) 互联网的发展是区域经济发展水平的反 映， 同时也具有自身的特点。

The rapid increase in economy and high- speed development in information industry have made Internet in China grow quickly. Meanwhile, the social informationization step has accelerated and regional information disparities have emerged. Combining the number of domains in each province with maps, this paper discusses these disparities in China spatially and temporally. Meanwhile, we improve some methods of correlation analysis, Lorenz Curve and location quotient et al., which are different to the traditional economic ones such as GDP. The conclusions are as the following: (1) The Internet development in China declines gradually from Eastern China to Western China. (2) The gap between high level provinces and low level ones was big. For example, in 2001, domains in Beijing were 442 times as much as those in Qinghai province. (3) Although the absolute disparities between Eastern China and Central China as well as Western China were widened from 1999 to 2005, the comparative disparities in each province were constant by and large. (4) This paper classified provinces into five categories using location quotient, which represents the difference with the average level. The classification distribution showed that the Internet development in Eastern China was increasing, in contrast to the stagnation in Central China and Western China. So, the development in Central China and Western China should be paid much attention to by the government. (5) The spatial distribution of domains was consistent with that of provincial GDP, but not accordant absolutely.
