Urban spatio-temporal behavior from the perspective of households: Research progress and framework

Households are a key carrier for urban spatial reconfiguration and socioeconomic transition, and also a crucial intermediate level between the individual, the community, and the city. Existing studies have recognized the importance of research on spatial-temporal behavior from the perspective of households, but they usually take the characteristics and division of responsibilities of households as background and explanatory factors. The interactions and connections between household members are rarely considered, and the complexity of intra-household behavioral interactions of various households and different types of behavior is not well understood. This research focused on household and intra-household behavioral interactions. First, it created a time-spacesociety framework to measure behavioral interactions in three dimensions, that is, temporal interaction, spatial interaction, and social relationship interactions, and refined the patterns of intra-household behavioral interactions. Second, it revealed the mechanisms of influence and effects of intra-household behavioral interactions, taking China's socioeconomic background into account. Finally, aiming to improve the quality of life of household members, it proposed an optimization scheme of living space with the household-friendly orientation. The research contributes to reintroducing the household level in urban research based on spatial-temporal behavior, and promoting behavioral geography research to emphasizing individuals' interactions. It also provides new ideas for examining social issues such as fertility, as well as child and elderly care, offering a scientific reference for the optimization of community life circle and urban space, and promote household-friendly urban planning and social governance.
