This study investigates the optimal model for fostering resident support for tourism development in the Davao Region by examining the roles of affective solidarity, quality of life, and community attachment. The data were collected from 462 residents in four critical locations using a non-experimental route analytic methodology. The results indicate that emotional solidarity substantially impacts community cohesion and collaboration despite its less direct function. The results emphasize the significance of fostering a sense of community and enhancing living conditions to facilitate the expansion of tourism. This research contributes to the literature on tourism development and sociology. It also provides policymakers with practical insights that will help them align sustainable tourism expansion with the community's welfare.
