利害關係人需藉由管理當局揭露的資訊來降低其與企業之間的資訊不對稱,而董事會規模與企業的資訊揭露政策及水準相關。本研究以人工蒐集我國上市櫃公司2014年至2016年間的企業社會責任報告書並建構揭露品質指標,實證結果顯示:董事會規模與報告書品質相關,而此項關聯性會因企業社會責任報告書(corporate social responsibility reports, CSRR)係強制揭露或自願揭露而有所不同。因此,本研究建議,主管機關應強化與報告書揭露內容有關的規範,並鼓勵企業擴大董事會的規模,以改善報告書的揭露品質。
Stakeholders rely on the information disclosed by the management to reduce information asymmetry between the firms and the stakeholders. As prior studies indicate that board sizes are associated with the disclosing policies and levels of the firms, this study explores the association between board sizes, voluntary/mandatory disclosure, and corporate social responsibility reports (CSRR) quality by constructing the CSRR quality indexes for the hand-collected 2014 to 2016 CSRRs of publicly listed companies in Taiwan. The empirical results show that board size relates to CSRR quality and the above relationship differs among mandatory and voluntary CSRRs. This study suggests that the regulator should encourage firms to expand board sizes and mandate higher-quality disclosure in CSRR to improve CSRR quality.
