立法委員職位得來不易,然而我國不乏有立委在任期內,轉任地方縣市首長、入閣擔任政務官之「跳板行為」。本文以第八屆、第九屆立法委員為研究對象,主要分析立法委員跳板行為之因素,透過訪談立委與蒐集公開資訊等兩種管道,將資料進行迴歸分析與測試,以立委之「個人因素」與「立法績效」檢證立委之跳板行為。本文發現:性別、年齡與是否出生於政治家族等個人因素,以及法律提案數等立法績效,確實與立委跳板行為有正相關影響。同時,本研究也發現基於總統國會制特徵,雖然我國不乏有立委進行跳板行為,但整體而言僅少數比例立委於任期中轉換跑道,此外,政黨之間相比,泛綠政黨更加偏向以立委作為政務人才甄補來源。
Achieving the position of legislator is not easy. However, there are many legislators in Taiwan who are transferred to serve as the Mayors of local government or as administrative officials in the cabinet during their term of office. This article focuses on the eighth and ninth legislators as the research object. It mainly analyzes factors that affect the springboard behavior of legislators’ by conducting regression analysis and testing on the data through two channels: interviewing legislators and collecting public information. This study uses two variables: the "personal factors" and the "legislative performance" of legislators to verify the legislator's springboard behavior. This study found that personal factors such as "gender", "age" "whether born in a political family" and legislative performance such as "number of legal proposals" do have a positive correlation with legislators' springboard behavior. At the same time, this research also found that based on the characteristics of the president-parliamentary, although there are many legislators in Taiwan who have springboard behaviors, on the whole, only a small proportion of legislators actually change the track during their term of office. In addition, when compared with the two main political parties in Taiwan, pan-green parties are more likely to use legislators as a source of talent for government affairs.
