論文提要
本研究目的在於探討新上市公司在申請上市時所編製的強制性財務預測與上市後業績變動及盈餘管理的相關性。
本研究採實證之方式，選取民國80年6月到86年底之新上市公司曾在上市當年及上市後三年內公告或更新財務預測者。利用迴歸分析、卡方分析、T檢定及Wilcoxon Rank Sum 檢定，而研究結果如下：
1. 由於新上市申請的相關規定，若公司預期本身經營績效不佳時，會提出較為樂觀之財務預測，以利上市審查。
2. 新上市公司上市後的經營績效變異程度與財務預測的過度樂觀程度呈現正相關，但是當樂觀程度定義為來自營業活動的現金流量時，並不顯著，可能是公司僅需注意營業毛利與稅前淨利是否達成，對現金流量之預測較沒有達成的壓力所致。
3. 新上市公司提出之強制性財務預測過於樂觀者在上市前盈餘管理之現象並不顯著，其可能原因在於本研究採用之盈餘管理定義僅限於與營業有關之裁決性應計項目，而無法看出公司利用其他項目來進行盈餘管理。
4. 上市前從事盈餘管理之公司，除了現金流量之準確度不明顯外，業績衰退和業績成長公司在財務預測準確度上明顯不同，但是在財務預測更新行為上並無顯荖不同。
5. 新上市公司面臨更新財務預測時，會傾向利用應計項目操縱來規避調整。 / The Relationship among Change in Operating Perfomance, Earning Management and the Revision of Mandatory Forecasts
Abstract
This research aims to examine the relationship among change in initial public offering firms, earning management and the revision of mandatory forecasts. This study contends that the forecast revisions should significantly correlate with changes in IPO's performance. The samples of this study range from June 30th, 1991 to December 31st , 1997. The empirical results of this study can be summarized as follows:
O Due to related regulations, if IPO firms predict its insufficient operation performance, the mandatory forecasts of IPO firms are usually optimistic, for the convenience of examination.
O The IPO firms' variation degree of operation efficiency and the over-optimistic forecasts are correlated positively.
O If IPO firms' mandatory forecasts are over-optimistic, the earning management is not correlated significantly.
O Before public offering, among the firms which manipulate earnings, there is significant difference between firms with declining performance and firms with growing performance.
O When the IPO firms face revisions of forecasts, the firms would tend to manipulate accruals to avoid revisions.
