摘要

面對健保局年年虧損、財務警報下，一代健保因保費跟不上醫療支出，經費預估只能撐到民國101年，為穩固健保財源使健保永續經營，以確保國人健保就醫權，立法院審議通過的二代健保法，該法案於民國100年1月4日經立法院三讀通過。二代健保中擴大費基的補充保費收取，對以營業項目中利息逾五千即就源扣取之交易成本與避稅影響，或獎金佔薪資比例高的產業如金融保險業、電子業等影響較高。因此本研究以事件研究法，按照立法程序探討「二代健保」制定過程，對金融類股與電子類股價報股酬之影響。
　　實證結果發現，金融類股、電子類股之企業，在二代健保制及審議的過程中，相較於其他類股之企業，有顯著負向的累計異常報酬，即該類股的股價受二代健保制訂及審議的影響較大。二代健保的實施的確會影響投資人對金融類股、電子類股的投資意願。
