In China, policy-driven rural renewal projects have transformed many village public spaces, but some renewed sites are still weakly integrated into villagers’ everyday routines. This study asks why some renewed public spaces sustain routine use and low-intensity social interaction, while others remain materially complete but socially weak. The study was conducted in a rural township in Puyang County, Henan Province. Twelve renewed public spaces across several villages were examined through structured spatial audits and 579 resident questionnaires. Five spatial conditions were assessed: visibility, stay support, activity accommodation, interaction-supportive arrangement, and experienced locational convenience. Two behavioral outcomes were used to describe post-renewal vitality: use frequency and social participation. The analysis combines necessary condition analysis (NCA) and fuzzy-set qualitative comparative analysis (fsQCA). NCA is used as a diagnostic tool for identifying upper-limit constraints, while fsQCA is used to identify sufficient combinations of conditions. The results suggest that experienced locational convenience is the clearest bottleneck condition for both outcomes. When a site is difficult to incorporate into residents’ daily walking routines, internal design quality has limited capacity to translate into sustained behavioral use. Among better-located spaces, high vitality is associated with several design configurations. The most stable recurrent pattern combines visibility, stay support, and locational convenience as core conditions, together with either interaction-supportive arrangement or activity accommodation. Low-vitality spaces follow a different logic, being characterized by the simultaneous absence of several supporting conditions rather than by the absence of one isolated feature. The paper therefore proposes a two-step diagnostic logic for rural public-space renewal: first checking whether a site is embedded in everyday mobility and then matching internal spatial conditions with local patterns of use.
