Neighborhood attachment has barely been the focus of smart community development. This study conducted a field survey to investigate how smart renovations affect residents’ neighborhood attachment in two neighborhoods in Beijing, China. The PLSPM method and the multi-group analysis were applied to analyze the data. It was found that the perceived quality of smart services indirectly increased neighborhood attachment, but the direct effect was smaller than the indirect (mediating) effects via social capital and residential satisfaction. The indirect effects of residential satisfaction on neighborhood attachment were smaller than the mediating effect of social capital on neighborhood attachment.
