Digital transformation means that digitalized information extends in the industry over time and eventually spreads across society. This concept used to be defined and applied in the industry fields. Nowadays, the extended meaning could also be applied to the entire business process such as production and distribution of companies, and it is even changing our society not only in the industry but also in our everyday life. Spatial changes in cities that digital transformation brings are still underway everywhere. This study aimed to assess the changes that digital transformation could bring to the lifestyles of citizens and the spatial changes especially in metropolitan Seoul if this trend continues amid the huge social changes of digital transformation.

This study assumed that urban spatial changes caused by digital transformation are related to transportation and land use. Therefore, studies and literature on urban land use, transportation, and predicting future urban spatial changes as well as their interactions were reviewed. We could access and analyse how they predicted lifestyle and spatial changes in the future at that time. It was intended to see what was predicted and how much has been realized among them. To obtain information about the realization of forecasts, experts in the industrial sector, which are enormously affected by digital transformation, were consulted on current change and future development. We also met and interviewed academic experts to reflect their views. In addition, about 80 experts were asked for their opinions on the above topics and on changes in urban space due to digital transformation in the future.

Through digital transformation, new technologies, ordinary life, and urban space are driving convergence. These changes influenced the needs of citizens and brought an enormous change to the market. The key was flexibility. Seoul needs an urban planning instrument that can quickly capture the needs of citizens and the market to adjust their changes into new planning concepts flexibly. In addition, our society should consider the underprivileged classes in digital transformation. For that Seoul needs interdisciplinary researches beyond fields. Within these researches, spatial policy could deal with future themes properly through monitoring three-stage such as industrial structure, lifestyle, and urban spatial change.
