中文摘要：

互联网信息流的空间格局和组织机理是信息地理研究的重要命题。通过获得87个国家的信息流、互联网质量、人口与GDP、技术流、资金流、物流和人流等7大类16项指标数据，利用洛仑兹曲线和多元回归方法，探讨世界互联网信息流的空间分布格局、组织机理和影响因素。研究表明：世界互联网信息流的空间格局呈现出美国为中心，欧盟和东亚为两翼的“中心两翼”型；组织由ICANN、国家、国际大都市和跨国企业4个层面实现；格局形成主要是各国GDP总量的反映，同时受到其他多因素影响；“流动空间”中的5种流态间是相互作用的。

英文摘要：

The spatial pattern and organization mechanism of International Internet Information Flows （IIIF） in the IPv4 time is an important proposition of information geography. This paper reveals the spatial distribution pattern, organization mechanism and influencing factors of IIIFs, to make up the explanation insufficiency on the reason and present situation ofinternet spatial distribution imbalanced in the domestic and foreign geogra- phy filed, aiming to help the worldwide scale scientific cognition about ＇the digital gap＇ phenomenon. First the paper analyzes 16 target data of 87 main countries all over the world, such as gTLD, IPv4 address, netizen quantity, NRI, total population, urban population, total GDP, per capita GDP, patent quantity, FDI inflows, FDI outflows, merchandise imports, merchandise exports, international tourism arrivals, international tourism departures and students in abroad, and then categorizes them to 7 groups, such as the information flow, the Internet quality, the population and GDP, the technology flows, the caoital flows, the material flows and the people flows. According to the Lorenz curve and the multiple regressions, the paper analyzes the characteristics of above factors and the relationships among them, and findings shows that centralization index ofnetizen distribution from 87countries reduced to 0.761 in 2007 from 0.824 in 2000. Although the imbalanced distribution situation is obtaining the alleviation gradually, ‘the digital gap＇ question is still stern. The conclusion is that the international Internet spatial pattern is ‘one center-two wings＇, which makes United States as center,European Union and Eastern Asia as two wings; IIIF organization was realized by ICANN, the country, the international metropolis and the Multinational corporation in 4 stratification planes; The formation and development of international Internet information flow space pattern is reflection of total GDP in various countries; The relationship among the information flows, people flows, m
