手机用户、手机网民规模的不断增大意味着移动信息技术的出现和应用带来了信息革命的第二阶段。移动信息技术开始赋予了空间以新的内涵，其影响下的空间结构成为地理学研究的主要内容之一。本文重点梳理西方学者近些年来关于移动信息技术及其影响下的城市研究范式、研究内容变化的最新成果，以期了解最近的学术动态，并为国内相关研究提供一定借鉴。

英文摘要：

The constant increase on the scale of the cellphone users and netizens signifies that the appearance and the application of the mobile information technology have entered the second stage to the information revolution. With the arrival of the era of the mobile information, the study on urban space structure is under- going the new transformation as followed： to begin with, due to the increase of the popularity rate of the mo- bile facilities, it becomes more and more important for the cellphone and Google as a new means to geo- graphical study on the era of mobile information. Then, in the previous study on the influence of information technology to space, the quantity of intemet domain names and the capacity of backbone network bandwidth are the main indicators to the study on urban network named urban space structure. Next, from the present view point, the study in the west runs faster than that in the home, and the study contents abound than domes- tic which is merely involved in the study on resident behavior, space time constraint, cyberspace, and urban network. The study home and abroad, however, places particular emphasis on urban out space structure, and it needs concerted effort of the new data, means and concept to step into the study on urban functional space based on the achievement of personal study. Furthermore, the appearance and application of the mobile infor- mation technology is the second stage to the information revolution. The combination between wireless net- work and mobile facilities motivates the development of mobile service as well as creates a new era of mobile information. ＂The New Mobilities Paradigm＂ bridges the difference between space issue and mobility. The geographical study is faced with further complicated objects and the methods need the multi- disciplinary in- corporation and the application of the new technology. At last, the geographical space study in the influence of mobile information technology focuses mainly on both cyberspace and physical space.
