The purpose of this study is to research the history of Street Dance in Taiwan, and the influence factors of developed situation in recent years. Street Dance is one of the elements of Hip-Hop, which is a youth subculture. The origin of Hip-Hop was from Bronx, New York City in USA, Hip-Hop is a big influence for teenagers and society since it came into Taiwan. That is the reason why I intend to make sense for public to know more about the situation and history of Hip-Hop through a systematical generalization, and figure out strategies to push Street dancers and workers up to a more high level. The study is mainly going down with in-depth interview and also notes. I used the method of category analysis to get a more objective and completed result, which is arranged as the following: First, developing Street Dance in Taiwan can be classified as the way dancers study, the space and time for training, atmosphere between dancers, style and technic, competitions and events, amount of dancers, frequency of exposure on media, value for government, education about Hip-Hop, interests of public, attentions from sponsor, support from family. Second, effected factors of developing in Taiwan include spreading of media, raising amount of dancers, demanding and effecting of business market, interpersonal relationship, image of Street Dance, directed education. Third, the development in the future has off-stage works, life style, official Street Dance, people, communication with public, education, style and unique, passing down. The study could be multiple and base on science to provide an abundant library of Hip-Hop, promote it into a more complete development and environment.
