The development processes Taiwan¡¦s indigenous languages have gone through three hundred years of Foreign and Ethnic Chinese influence and assimilation. Languages belonging to Bu group of the western lowlands of Taiwan have mostly become extinct, there are only two or three languages belonging to this group that are worth listing. However even these few remaining languages are quickly dying out. From 1949 onwards beginning with the Republican (ROC) governments¡¦ promulgation and strict enforcement of National Language (Mandarin Chinese) education policies the number of speakers of Indigenous language groups sharply diminished, and with them a great amount of their language, cultural practices and cultural identity have also been lost. This is especially so in urban areas where members of indigenous group must compete in a multi-ethnic society where they are only exposed to the dominant language media outlets, the result being a worsening trend of these culture groups placed at a greater disadvantage and language development has become increasingly difficult. As a basis for Indigenous language groups continuing development in urban areas as well as saving and reinvigorating Indigenous languages and cultures on the brink of disappearing, it has now become an urgent topic if discussion to promote Indigenous cultural and linguistic development. This dissertation aims at promoting the languages and cultures of Indigenous people residing in urban areas from a strategic viewpoint in order to expand on the work of Indigenous language development. The content of this work will be roughly split between theory and practicum. In dealing with issues of theory we shall use sources from a wide body literature including historical data, government policies, and benefit factors taken from surveys and questionnaires that will be used to analyze variables. As for practicum, we shall proceed to use research methods of strategic promotion. We will also incorporate SWOT analysis to clarify the purposes of Indigenous groups in target municipalities and the most important problems therein. In the target municipalities of urban areas where Indigenous people reside we will seek to analyze our most important subject ---that being the problems faced by disadvantaged youth among Indigenous people in urban areas. As to the needs of entire groups and dealing with competitors we must implement mixed marketing strategies. There must also be a plan arranged from the standpoint of the public agencies that would imperatively promote the language development from urban areas to each tribal settlement.
