本文旨在檢視企業社會責任與資訊不對稱之直接關聯。透過股票市場上的買賣價差,據此直接衡量企業資訊不對稱的程度。過去文獻已證實公司治理能減緩資訊不對稱之問題,本研究進一步分析,公司治理能加強企業社會責任減緩資訊不對稱之問題。實證結果發現,企業在台灣目前可能還無法真正落實企業社會責任,故企業社會責任減緩資訊不對稱的程度並不顯著,加上,因本研究採用之樣本為TOP50之企業,進行同規模同產業一比一配對方式取樣,無論是否執行企業社會責任相對的這50間企業之公司治理都算良善,導致公司治理對於買賣價差之影響並不顯著。
The purpose of this paper is to examine the corporate social responsibility associated with asymmetric information.The bid-ask through the stock market, on the basis of direct measure of the degree of enterprise information asymmetry.The past literature has confirmed that the corporate governance will slow down the problem of asymmetric information,this study further analysis, corporate governance can strengthen corporate social responsibility to slow of the asymmetric information problem.In this study, because the sample of the TOP50 of the enterprise, carried out with the same industrial scale of one to one pairing sample, regardless of whether the implementation of corporate social responsibility because opposite of these 50 companies are also considered good corporate governance, resulting in the bid-ask by influence of corporate governance is not significant.
