中文摘要：

进入21世纪以来，中国的互联网事业飞速发展。无论是网民规模还是网站数量，都有了较大幅度的增长。本文基于互联网产业的生产与消费两个方面，利用锡尔系数和集中化指数等方法，对2000年至2009年中国（不包括港澳台地区）31个省（市、区）的互联网产业发展状况进行了一系列研究。结果发现：中国互联网产业发展的区域差异仍然十分显著，但消费层面的省际差异明显小于生产层面，而且消费层面差异缩小的幅度也明显大于生产层面。同时，从空间来看，东部地区的变化显著，大部分省市有了较大发展，但中西部地区的大部分省份仍处于低消费—低生产的状况。

英文摘要：

China＇s Internet industry has been maintaining a rapid growth since 2000. Both the number of Internet users and www domain names are showing a strong momentum of development. Based on the two dimensions of production and consumption,the article uses Theil index and centralization index to study the regional differences of Internet penetration rate and www domain names per ten thousands among 31 provinces,autonomous regions and ,municipalities directly governed by the Central Government from 2000 to 2009. The results show that there are still very significant regional differences in the development of China＇s Internet industry. The inter-provincial differences in consumption dimension was significantly less than the production dimension,and narrowing the gap in the range of consumption dimension was significantly greater than the production dimension. At the same time,from a spatial perspective,significant changes in the eastern region,most of the provinces and cities have undergone considerable development,but most provinces in central and western regions is still low consumption and low production conditions.
