本研究主要探討臺灣地方法院民事訴訟案件，透過會計鑑定之輔助，是否可以提升訴訟之經濟性。本研究將訴訟之經濟性分別以上訴與否、維持原判決與否、和解與否三項變數來加以衡量，採行法律實證分析。實證結果顯示執行會計鑑定不能夠降低兩造當事人上訴之比例，且達統計顯著水準、不能增加上級審法官維持下級審法官判決之比例，但未達統計顯著水準、不能增加兩造當事人和解之比例，但未達統計顯著水準。推論原因為有執行會計鑑定之案件其案件本身較為複雜且困難，而複雜案件本身上訴率即較高、維持原判決率即較低及和解率即較低。 / The purpose of this study is to investigate whether using forensic accounting litigation support service to assist civil litigation cases proceeded in Taiwan District Court enhances the economics of litigation.
