本研究係探討法人說明會影音資訊與價值攸關性之關聯。近年來,由於法人說明會所揭露的資訊與揭露的方式相較於其他資訊揭露管道更能提供具資訊內涵的資訊給市場投資者,因此法人說明會已逐漸成為公司與投資者溝通的重要管道之一,金管會更於近年來持續修法,於2016年3月修定國內上市櫃公司須每年至少自辦或參加一次法人說明會,以增加市場資訊透明度。本研究提供實證結果證明,法人說明會中所揭露的正面財務資訊與正面盈餘與非盈餘資訊皆會使盈餘價值攸關性上升,權益帳面價值之價值攸關性下降。本研究透過實證研究發現,管理階層於法人說明會中揭露較多正面財務資訊、盈餘資訊與非盈餘資訊皆會給投資者公司營運狀況較良好的正面訊息,因此在做決策時會傾向於依賴盈餘資訊,顯示法人說明會的資訊可以揭露額外資訊給投資者,作為其判斷做決策時應依據盈餘或權益帳面價值資訊的重要訊息,同時也能透過本研究使管理階層意識到法人說明會對市場投資者的影響,提高管理階層對法人說明會的重視,以增加市場之資訊透明度。 This study examines the relationship between information of video conference call and value-relevance. Recently, the conference calls have been one of the significant communicating methods between companies and investors gradually because the information disclosed in conference calls and the way of conference calls are different from other communication methods. Besides, Taiwan Financial Supervisory Commission(FSC)revised the law to require that listed companies have to hold or participate conference calls at least one time every year in March 2016. The purpose of the law is to increase information transparency.In this study, we find that positive financial and positive earnings and positive non-earnings information disclosed in conference calls will increase earnings’ value-relevance and decrease equity book value’s value-relevance. We provide evidences that when management disclosed more positive financial, positive earnings and positive non-earnings information, they will convey the message that the companies are in good shape to investors and lead investors to rely on earnings information when making decision. Hence, this study contributes that conference calls can provide additional information to investors, help investors making decision and raise the awareness of the management to put more focus on conference calls.
