Place attachment is the bonding based on positive affection in the interactions between people and a place that significant for the harmonious relationship between people and the environment. Scannel and Gilford (2010) considered the dimensions of place attachment and proposed the theoretical framework of Place, Person, and Process (PPP), which should be systematically studied from the perspective of person, place, and psychological processes. The purpose of this study is to investigate and analyze the theory of place attachment and put forward the hypothesis for the structural model. The potential variables of the model were analyzed, and the correlation coefficients were obtained. In view of the results of the structural model analysis, relevant policy proposals were put forward. After the questionnaire investigation on the Haneul Park in Daejeon city, the data were analyzed using the structural equation modeling (SEM) method, and the model with 19 measurement items was established. The results showed that the hypothesis model was suitable for the data because the 𝒳² test of the model fitting was not significant (p=0.349), and it had a better model fitting index. The results demonstrated that the place, cognition, affection, and behavior have significant effects on place attachment (p<0.05).They play the most important role, considering that the relationships between the variables, correlation coefficients between cognition and affection, cognition and behavior, and behavior and affection were significant (p<0.01). This showed that the place attachment process for the park visitors involved the psychological emotional cycle of cognition, affection, and behavior. To increase the interest of visitors and the rate of revisit, it was suggested to increase the diversity of the park facilities and to meet the needs of local residents when the construction and renovation of neighborhood parks is undertaken. In internal aspects, the paper studied in detail the psychology or expectations of park visitors and showed the importance of the analysis of their emotion, cognition, and behavior. This analysis can be a starting point for the design and renovation of the neighborhood parks. It should improve visitor satisfaction and strengthen the attachment of visitors to the neighborhood parks.
