The idea of new urbanism advocates for promoting social support, defined as the network of care or help a person receives from non-family members, by improving the walking environment and other components of new urbanism. However, the impact of the walking environment on social support, especially from the perspective of older adults’ perceptions, remains unclear. In a rapidly aging urban environment, the demand for walkable living spaces has increased among older adults. One typical measure of the walking environment, walking accessibility, often focuses on travel time and/or distance to different urban opportunities but ignores travelers’ subjective feelings and experiences about the walking environment. These subjective factors are important for policymakers to design, implement, and regulate appropriate plans and strategies to enhance social interaction among older adults at the community level. This study examines how, in the Chinese context, the perceived walking environment is associated with social support, mediated by walking time and perceived level of safety, using generalized structural equation models with data from the 2021 Chinese General Social Survey (CGSS). The results show that, as compared to walking time, perceived safety is more likely to be influenced by the perceived walking environment, which positively correlates with social support. This suggests that older adults feel more socially supported by their neighbors when they perceive their living environment as safe and walkable. These findings provide new evidence for decision-makers to develop and implement targeted policies on walking accessibility for older adults with better understanding of the relationship between the perceived walking environment and social support.
