Based on the theory of Spiral of Silence from Noelle-Neumann, the main purpose of this research is to figure out internet users how to express their opinion after evaluating opinion climate and whether the characters of the Internet make their opinion- expression arbitrarily. Moreover, this research focuses on Chinese ¡¥face¡¦ culture to examine the cultural context how to influence opinion- expression of internet users. This research chooses ¡¥PeoPo¡¦ citizen journalism platform as research field, and adopts in-depth interview to analyze the opinion- expression of 9 PeoPo citizen reporters. As for the research topic, it¡¦s concerned with the issue of village migration of Taiwanese aborigine after the disaster caused by Typhoon Morakot in 2009. Therefore, this research attempts to figure out the PeoPo citizen reporters¡¦ inner process of opinion- expression and the influence of Chinese face culture. This research finds that the opinion-evaluation of internet users mainly rely on the Internet, and the fear of isolation that the spiral of silence theory emphasizes don¡¦t predict their willingness to speak up alone, but Chinese face culture does. Furthermore, the characters of the Internet don¡¦t prevent the spiral of silence effect. Although PeoPo not only accepts diverse viewpoints widely, but also inspires more citizens to voice local issues, the results show that actually PeoPo citizen reporters express their opinion with great pressure mostly lowering their willingness to speak up such as the foundation idea of PeoPo, reference group, threat of opposition, objective principle of journalism, and Chinese face culture. In sum, getting one¡¦s own way is discouraged on PeoPo; in other words, the characters of the Internet still unable to relieve PeoPo citizen reporters of speaking up.

在這個新媒體時代，人人都有機會成為公民記者。本研究旨在探討一群不為金錢、不僅是為了組織發言的高參與度公民記者，試圖了解其形貌，以及持續不斷發文的原因。採用人本心理學之父Maslow的動機階層理論做為研究梗概，以PeoPo公民新聞平台中的公民記者為研究對象，從符合研究條件的公民記者中，隨機挑選八位公民記者進行探究。 本研究採用文本分析及深度訪談做為研究方法。透過文本分析，分析八位高參與度公民記者在平台上發表的所有報導，了解發文頻率、型態、文章與Tag分類、節目採用與讀者回應狀況…等五個類目，並輔以半結構式深度訪談，達到主客對照，進行探討。 經由研究後發現，這群高參與度公民記者有三個特色：（1）中壯年；（2）上班族；（3）社區大學成員、課程培訓學員、志工。他們對於報導公民新聞保持著相當積極的態度，主要採用影音方式呈現，其新聞常受到媒體採用，且有一定的讀者回饋。在製作公民新聞的過程中，「歸屬和愛」、「自尊」、「自我實現」三個需求，是高參與度公民記者最主要的參與動機，其中，「自我實現」更以Z理論中「健康型自我實現」為主。 / Everyone has the opportunity to become citizen journalists in this new media age.
