Theoretical construction of urban physical-virtual activity system

Human society is currently in the stage of significant digital transformation. The basic characteristics and internal mechanisms of human activity systems are undergoing major transitions. In particular, activities in virtual space are becoming diversified and self-systematical, and they more actively and frequently interact with the activities in the physical space in a complex way. At present, research on the digital transformation of human activity system increasingly emphasizes the variation and complexity of the behavior in virtual space. The research also highlights the necessity to go beyond the duality of physical and virtual space and to integrate technological use with activity system. This paper innovatively proposes the concepts of urban virtual space activity system and urban physical-virtual activity system. On the one hand, the new concepts emphasize the characteristics of urban virtual space activity that it increasingly becomes an independent activity system (of urban physical space activity). On the other hand, the concepts focus on the interaction relationships between urban physical and virtual activity systems. The theoretical construction of urban physical-virtual activity system can deepen the understanding of the digital transformation of urban activity system and further provide policy implications. This paper systematically states and discusses the conceptual and research frameworks of urban physical-virtual activity system in the dimensions of theoretical and methodological innovation, empirical topics innovation, and practical innovation. The concept and elements of urban physical-virtual activity system can provide new theories and methods to analyze urban space in digital transformation, and scientific support for urban life circle planning in smart cities and governance of digital life. © 2024 Science Press.
