隨著資訊網路的普及與服務功能的多樣化，電子通勤、電子購物、遠距教學、遠距醫療、電子化政府、電子會議、電子銀行等項即時且及戶的服務，可解除活動的空間限制，令個人或企業組織可在任一空間區位進行多樣活動，都市活動系統面臨急遽的結構性轉變。資訊與電子通訊科技結合之電信資訊科技（telematics）之應用造成通訊活動方式及強度改變，對於活動之時空關係、特性及空間發展均造成影響。本文分別針對空間活動及土地使用型態之可能影響進行分析，探討電信資訊科技應用對於住宅及辦公室區位選擇、土地使用分佈型態及都市結構之變化。

As the popularity of information networks and the variety of relative service, telecommuting, teleshopping, teleeducating, telemedicining, telegovernment, teleconference, telebank provide in time and in door service. These technologies could release the spatial constrain and make the individuals or corporate proceed any kinds of activities in any places. Therefore the urban activities system face the rapid change. The usage of telematics which is combinated with information and communication technologies, could possibly change the pattern and density of communication, and effect the relationship between time and space, the characteristics of activity, and the spatial development. This paper analyses the possible change of spatial activities and land use pattern, and discuss the changes of the housing and office location choices, the land use patterns and urban structure by the usage of telematics.
