隨著政治民主化以及公共議題的多元化，政府溝通能力逐漸受到重視。許多政策推動的失敗被歸咎於政策溝通成效不彰外，文官更是被迫到第一線與民眾進行溝通互動以滿足逐漸高漲的溝通需求。然而，對於文官政策溝通行為的規範性及經驗性研究均相當匱乏，本研究從政府與民眾的互動關係、不同政府運作模式的邏輯，釐清並建構文官與民眾溝通的脈絡以及影響其溝通途徑與行為之因素，並試圖解釋文官參與政策溝通對於政治行政二分的意涵。 本研究以原能會為個案，透過訪談17位原能會文官、記者以及社運團體，蒐集原能會在不同溝通場域中的溝通經驗作為歸納與分析的素材。經過經驗資料的堆砌與歸納，建構政策溝通系統用以解釋影響原能會組織溝通途徑的選擇及其文官個人溝通行為的因素。研究發現行政組織有趨於選擇單向溝通的傾向，及趨於偏好使用間接管道溝通的傾向，並提出環境、制度、組織與個人層面對於溝通途徑選擇及溝通行為的影響因素。最後，本研究提出幾項建議，首先，原能會未來應重視記者對於政策資訊的理解；其次，應避免跨途徑溝通；其三，應正視反核態度的民眾，提供適當的溝通途徑；最後，未來應以團隊為政策溝通的行動單位，團隊應涵蓋不同層級的成員，以面對各式樣的問題，進而避免溝通困境的產生。 / In recent years, government communication capacity has become important as political democratization and public issues have diversified. Policy failures are often attributed to the lack of policy communication and force the civil servant to communicate with the public directly. However, some of the communication behavior of civil service policy literature suffer from the lack of attention to the perspective of normative and empirical researches. This research intents to explore the communication context between civil servant and the public, and to find out the determinant factors which affect communication approaches and communication behavior. This research uses the methods of in-depth interviews with key informants to investigate the key factors in the policy communication system that have substantial affected the choice of organizational communication approaches and communication behavior of civil service in Atomic Energy Council. The result indicates that: First, the public sector still has a tendency to choosing one-way communication and using indirect channel to communicate. Second, this research offers critical factors from the level of environment, institution, organization and individual that affect the choice of communication approaches and communication behavior. Finally, this research suggests that: First, Atomic Energy Council should pay more attention to understanding of policy information from reporters. Second, Atomic Energy Council should try to avoid cross-approaches communication. Third, Atomic Energy Council should face up to anti-nuclear groups and provide suitable communication approaches. Finally, Atomic Energy Council should design a policy communication team which concludes different levels of members, in order to build up an effective coordinating channels.
