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.

在訴訟審理之過程中，鑑識會計輔助法官釐清複雜商業交易的角色，日趨重要。本研究以地方法院民事訴訟之判決書為研究樣本，探討我國司法體制下，當事人主動聲請鑑定、案件爭點涉及損害賠償、案件複雜程度以及當事人特徵是否為影響有權命行鑑定者命行會計鑑定決策之重要因素。本研究之實證結果顯示，在財務或會計相關之訴訟中，當事人主動聲請鑑定及案件爭點涉及損害賠償之判斷兩因素與命行會計鑑定之決策呈顯著正相關，表示此兩因素將使有權命行鑑定者命行會計鑑定之可能性增加。案件複雜程度(以原告聲明數量及是否有反訴衡量)與命行會計鑑定之決策呈現顯著正相關，表示當原告聲明數量愈多及有反訴之情形時，有權命行鑑定者命行會計鑑定之可能性較高。至於當事人特徵變數，研究結果發現，當事人為上市、櫃公司時，與命行會計鑑定之決策呈顯著負相關。亦即，當事人為上市、上櫃公司時，有權命行鑑定者決定命行會計鑑定之可能性較低。 / The legal supporting role of forensic accountant in litigation process via clarifying the complex business transactions has become increasing important in recent years. Based on a sample of civil litigation verdicts issued by district courts located in Taiwan, this study explores whether the presence of voluntary request for forensic accounting service by the plaintiff or the defendant, damage claim-related litigations, the complexity of litigations and the features of the litigation parties are associated with the decision made by the judge to request a forensic accounting service. The empirical results indicate that in financial or accounting related civil litigations, the presence of voluntary request for forensic accounting service and damage claim-related litigation issues are significantly and positively associated with judge’s decision to request forensic accounting service. This study also finds that the complexity of litigation cases (measured the number of plaintiff’s motions and a counter-claim made by defendant) are significantly and positively related to the use of forensic accounting service decision. With respect to the feature of litigation parties, the findings show that litigations with listed company as one of the parties are significantly but negatively associated with the use of forensic accounting service.
