However, the dynamics of social capital within these dis-tricts remain largely unexplored. As an initial step toward addressing this gap, this study conceptualizes changes in the social network of a commercial district community as shifts in social capital. Furthermore, it investigates the impact of information sharing within the community on this social capital. The study developed a framework to examine the relationship between social capital and so-cial networks. An empirical investigation involving ten participants and three experiments was conducted over three weeks. Results indicated that participants' subjective evaluations of store importance are influenced by the mode of information sharing within the community. Furthermore, the findings suggest that structured, repeated information sharing can strengthen interpersonal rela-tionships within the network. From a social-capital perspective, these findings imply that information sharing within interactive groups can potentially foster its development.
