(Background and Purpose) The rapid advancements in technology and shifts in economic structures have led to significant social mobility and physical environmental changes. These developments have accelerated individualization, resulting in the decline, disintegration, underdevelopment, transformation, and contamination of local communities. Amid this context, the expansion and transformation of physical spaces have caused both positive and negative changes in urban structures and infrastructure. Ultimately, these changes have contributed to the disintegration of community foundations and the emergence of various idle spaces.This study assumes that idle spaces can be regenerated or repurposed and aims to analyze the impact of such regeneration on the recovery of local communities, with sustainability as a key variable (mediating effect). Furthermore, it seeks to propose effective directions for idle space regeneration. (Method) This study begins with a theoretical review of idle space regeneration, sustainability, and the recovery of local communities by examining prior research on similar topics and identifying key characteristics. Based on this, a research model and hypotheses are formulated. Survey questions are designed using characteristics extracted from previous studies, and data is collected through a survey. The collected data is analyzed using parallel mediation effect analysis with SPSS 26.0 PROCESS macro to ensure accuracy and consistency. Finally, empirical data is used to select case subjects, and a case analysis is conducted through linear regression analysis. Through these steps, the study aims to suggest effective strategies for idle space regeneration. (Results) The analysis shows that space regeneration (X: independent variable) has a significant total effect (β=0.5521, p<0.05) and direct effect (β=0.5884, p<0.05) on local community recovery (Y: dependent variable). Furthermore, space regeneration (X) significantly influences sustainability (M: mediating variable) (β=0.8541, p<0.05). However, sustainability (M) has no significant impact on local community recovery (Y) (β=-0.0425, p>0.05), and the indirect effect of sustainability as a mediator is insignificant. (Conclusions) This study confirms through empirical analysis that space regeneration significantly impacts local community recovery and sustainability. However, sustainability does not directly contribute to community recovery as a mediating variable. The findings suggest that while space regeneration plays a vital role in enhancing community recovery and sustainability, sustainability's attributes do not directly influence community recovery. Additionally, the demographic analysis by age reveals that characteristics affecting regeneration and recovery vary across age groups, emphasizing the need to consider diverse demographic needs and preferences. In conclusion, by considering the characteristics of the variables identified in this study, it is expected that this research will serve as foundational data for promoting the recovery of local communities and improving quality of life through effective idle space regeneration.
