The public arts is an unstable and a sustained idea of development from ¡§percent for art¡¨ to ¡§new genre public art¡¨. The public arts of Taiwan and the community construction develop together over 16 years. This research believes that, the future evolution of public arts must be combined with the community construction and should become a kind of medium, a kind of esthetics element. The author propose three patterns of community intervention from experiences and practices ¡G¡§To participate and to communicate continually¡¨, ¡§the meeting of arts and life¡¨ and ¡§the dynamic relations who are mutually main parts¡¨. We all take economic growth as the essential target since long time in Taiwan. However, we still can not catch up synchronously the cultural taste and the aesthetic value. Taking ¡§Art as Environment in Chiayi¡¨ and ¡§living aesthetics movement of Taiwan¡¨ to collate Joseph Beuys¡¦s concept and position of ¡§social sculpture¡¨ and ¡§everybody is the artist¡¨, thinks that the arts are a part of life and no longer separated from the daily life already. What the research wants to explore is, the development of public arts in the future will be based on community construction, coordinate with the political pushing ¡§living aesthetics movement of Taiwan¡¨, raise people's esthetics accomplishment from daily life, and enable Taiwan to become a rich country both in economy and culture.
