Abstract:	公司在年報中所揭露的前瞻性資訊是分析師進行分析時的重要資料來源，本文主要探討前瞻性資訊揭露程度對於分析師預測的準確度以及分散度之影響。利用文字探勘技術，蒐集並分析台灣證券交易所公開資訊觀測站中所發布之台灣地區上市公司2012年至2016年年報，並根據資訊內涵將年報中的資訊分為前瞻性資訊、未來性資訊和可驗證資訊。研究結果顯示，企業年報中揭露越多前瞻性相關資訊可以顯著地增加分析師預測的準確度、減少分散度以及提升追隨企業的分析師追隨人數。而其中不同等級的前瞻性資訊有不同的影響，可驗證性資訊相較未來性資訊可以帶給分析師更多的資訊，而未來性資訊又比一般前瞻性資訊多。;Forward-looking disclosures revealed by annual report are a vital source of information when assessing a company. This study discusses the effect of forward-looking disclosures on analysts’ forecast properties, particularly focused on the analysts’ accuracy and analysts’ dispersion. This study is completed by using the text mining method to analyze annual reports between 2012 to 2016 in TSEC’s market, and then classify the information content into normal forward-looking disclosures, forward-looking disclosure with information on the impact on company’s future performance and forward-looking disclosure with verifiable information. 0The study indicates that the more verifiably relevant information the company reveals, the more analysts’ accuracy will become; the less dispersion will cause; and the more the analysts following. It is found that various level of forward-looking disclosures cause different effects.
