本文使用中華職業棒球大聯盟(CPBL)2003年至2018年間的球員資料，總樣本數為1940筆，包含1243筆野手及697筆投手。使用追蹤資料模型(panel data model)的隨機效果模型(Random effect model)進行分析。檢視轉隊球員的薪資與未轉隊球員是否有差異？接著進一步探討轉隊球員的薪資在轉隊前後是否有差異？ 實證結果發現，在同樣的個人特徵、個人球場成績下，轉隊球員的薪資都是顯著低於未曾轉隊球員。接著在球員轉隊前後的薪資分析也顯示，球員轉隊後的薪資顯著低於轉隊前，且野手的降幅較投手多。 ;This research uses 1940 observations (298 players), including 1243 field players and 697 pitchers from Chinese Professional Baseball League (CPBL) between 2003 and 2018.
