我國兵役制度在經歷了時空轉變，因應國際、社會環境、戰略需求考量的變遷，進行多次改革，五度調降義務役男役期，役男的訓練與役期長短，在社會上造成了不同的質疑聲音，因而本研究主要目的為檢視軍事訓練制度實行，影響台灣民眾對此議題的風險感知程度，探討媒體在影響風險感知中所扮演的傳播角色，以及政治信任與心理距離的影響，再進一步探討風險感知與自我效能感影響政策支持與行為傾向，結果顯示，電視新聞注意對個人風險感知具有顯著正相關，然而政治信任並不能預測風險感知程度，心理距離越近風險感知程度越高，政策支持及行為傾向會受到個人風險感知的影響，且自我效能感可以調節風險感知與行為傾向的關係。 

Military service system in our country has experienced time and space changes. In response to the changes of international, social environment and strategic needs, China has carried out many reforms. Five times of compulsory military service period has been reduced, and the length of training and service period of military service men has caused different voices of doubt in the society. Therefore, the main purpose of this study is to examine the implementation of military training system and influence the risk perception process of Taiwan people on this issue The results show that TV news attention has a significant positive correlation with personal risk perception. However, political trust can not predict the degree of risk perception. The closer the psychological distance is, the higher the degree of risk perception The higher the policy support and behavior tendency are, the more risk perception will affect them, and self- efficacy can moderate the relationship between risk perception and behavior tendency.
