Abstract: Websites aren’t only components of cyberspace, but also one of basic breakthrough points for studying cyberspace or internet from the perspective of geography. Differences exist in types of websites, websites of the same category, countries to which websites belong and service objects, where it is inevitable that impacts and presentation forms of geographical elements aren’t totally identical. However, geographical rules will be unified as long as websites are adequately famous with a huge amount of users to browse, register and log in to them. Laws of spatial distribution of registered website users are the most fundamental focuses, while Facebook is definitely the optimal case for a global study. This paper explores spatial distribution of Facebook users by considering number and penetration of users. Factors affecting spatial distribution of Facebook users are quantitatively and qualitatively examined. Quantitative indicators are selected on the basis of analyzing factors impacting distribution of individual netizens and those from different countries. After research, conclusions are reached as follows in this paper. Firstly, at the continental or national level, number and penetration of Facebook users greatly differ. Centralization index of the former is high, inclined to developed countries and nations with over 0.1 billion population, while the latter index is relatively high in Europe, America, Oceania and high income countries. Secondly, number of Facebook users is mainly impacted by three aspects factors of GDP, population size and number of netizens. Penetration is primarily influenced by multiple level factors of per capita income, urbanization rate, internet penetration and network infrastructure. In addition, transformation of internet surfing tools, cultural differences and network supervision system are important factors affecting spatial distribution of Facebook users. Thirdly, a basic premise for one to become a Facebook user is that he must be a. Thus, netizens is the most direct factor impacting the spatial distribution of Facebook users accordingly. On one hand, other factors mainly influence spatial distribution of Facebook users by affecting distribution of netizens. On the other hand, although spatial distribution of Facebook users and netizens correspond to each other to a great extent, it isn’t totally consistent. Fourthly, traditional geographical elements have indirect impacts upon spatial distribution of Facebook users. They impose impacts upon distribution of netizens, especially of Facebook users by affecting national economic growth, population distribution and cultural differences, etc.
