摘要

The market-oriented transformation of urban China has led not only to a radical change in urban space but also to a restructuring of residents' daily activity space. During this complicated process, problems such as spatial mismatch have accumulated and created obstacles to sustainable urban development. This paper reviews this transformation process from the perspective of daily activity space and finds that residents' daily activity space has transitioned from a daily life circle to an intertwined and expanded situation. Based on an analysis of the sustainability effects of this transition, this paper proposes the reconstruction of,a daily life circle under the market economy as an answer to sustainability problems.
