In the information age, the way people live has changed, which leads to the reconstruction of urban functions and forms, and therefore it is necessary to develop the compact city theory accordingly. This thesis firstly reviews the development history of compact city theory in different eras, and then explores the impact of information age on urban functions and forms, and considers that living space of people has changed from real physical space to physical space integrated with virtual network space in the information age. Finally, it is concluded that function division in the future city will be more blurred, land use will be more compatible and mixed, and the city’s structure develops from single center to multi-center or homogeneous center network, based on which new measurement index for compact city is proposed to measure compactness of city in the information age.encompact cityvirtual network spaceurban formInternetArticle2497-2504
