Based on the theories of community development and social network, the research will analyze how the government, community developing associations, and the inhabitants promote Hakka culture with the limitation of resources and finances while developing Hakka communities in the southern Taoyuan County. Through social network survey, and in-depth interviews with the association staffs from selective Hakka featured communities, the research hopes to structure how Hakka community development and network are arranged and promoted. The research also found that among the Hakka community developing associations in the southern Taoyuan County, the ones that play to the core, as well as the media, are mostly the leading and guiding communities in the whole Taoyuan County. These associations are rather active and aggressive when bringing Hakka elements into local events, making themselves distinctive from other communities. Meanwhile, sometimes the position of the association chairman is taken up by the head of the local village, leading the relationship between the associations and local communities to an either competitive or cooperative one. As to promoting Hakka culture, the associations gather the inhabitants' ideas mainly with innovative theme activities that include Hakka features and significations, thus to show the effects and influences brought by the Hakka community developing associations to the local communities.
