Abstract
In recent years, civic tech, in which citizens utilize open data and IT technology to solve problems, has become widespread. This research focuses on Code for Saga, a civic tech community in Saga Prefecture, and aims to clarify the actual situation and transformation of Code for Saga's activities and participants by analyzing the activity content and individual participation status. In this study, holding and participating in Code for Saga events were treated as civic tech activities, and we conducted a web survey and interviews with people involved in Code for Saga to organize the event content and the participation status of event participants. Through analysis, we found that the content of Code for Saga's activities changes depending on the social context, and that changes in the content of the activity also attract participants with different purposes, changing participant attributes. Furthermore, participants are also a factor in changes in activity content, and Code for Saga can be said to be a community that changes as participants and activity content influence each other. It was suggested that the civic tech community is not a community whose members and activity content are fixed like existing town development organizations, but where participants and activity content mutually influence each other, and the activities change. Furthermore, It was suggested that there is a property that it does not have a fixed mission from the beginning, but rather the personal interests and work-related interests of the participants resonate and spread within the civic tech community, and activities that lead to social.
