【摘要】:在證券市場上,外部投資者利用上市公司披露的信息進(jìn)行投資決策,由于信息的不對稱,上市公司的管理層占據(jù)著信息優(yōu)勢,而外部股東處于信息劣勢,信息披露容易出現(xiàn)信息失真,財務(wù)舞弊,投機(jī)行為等弊端,這嚴(yán)重?fù)p害投資者利益,影響企業(yè)健康持久發(fā)展。所以人們迫切要求找到影響信息披露質(zhì)量的因素,而完善的董事會治理是提高信息披露質(zhì)量的關(guān)鍵因素,因此,如何加強(qiáng)董事會治理來提高信息披露質(zhì)量是亟待解決的問題。 目前,國內(nèi)外現(xiàn)有文獻(xiàn)多是研究公司治理與信息披露質(zhì)量的關(guān)系,或者僅選取董事會特征中個別因素進(jìn)行研究,而本文直接從董事會治理的角度出發(fā),依據(jù)有效市場理論、信息不對稱理論和委托代理理論,提出研究假設(shè),實(shí)證檢驗(yàn)董事會治理與信息披露質(zhì)量之間的關(guān)系。 本文的核心內(nèi)容是對董事會治理與信息披露質(zhì)量的關(guān)系進(jìn)行實(shí)證研究。首先,選取深圳證券交易所343家非金融類上市公司的數(shù)據(jù),設(shè)定自變量:董事會會議次數(shù)、董事成員持股比例、獨(dú)立董事比例、兩職合一、董事會規(guī)模;控制變量:資產(chǎn)負(fù)債率、公司規(guī)模、凈資產(chǎn)收益率;對信息披露質(zhì)量的衡量,采用深圳證券交易所對外公布的信息考評結(jié)果,設(shè)定考評結(jié)果為0和1,并對變量進(jìn)行Pearson相關(guān)性檢驗(yàn),初步判斷變量之間不存在多重共線性。其次,建立實(shí)證模型,采用二項(xiàng)logistic回歸分析,檢驗(yàn)董事會治理與信息披露質(zhì)量的相關(guān)關(guān)系。最后,得出實(shí)證結(jié)果:董事成員持股比例與信息披露質(zhì)量顯著正相關(guān),董事會會議次數(shù)與信息披露質(zhì)量顯著正相關(guān),兩職合一與信息披露質(zhì)量顯著負(fù)相關(guān),而獨(dú)立董事在董事會治理中發(fā)揮的作用有限,對信息披露質(zhì)量影響不顯著,董事會規(guī)模與信息披露之間無顯著關(guān)系。 在本文最后,根據(jù)實(shí)證研究的結(jié)果,提出以下改進(jìn)措施:提高董事成員持股比例,加強(qiáng)對董事成員的股權(quán)激勵;董事會領(lǐng)導(dǎo)結(jié)構(gòu)上堅(jiān)持“二元領(lǐng)導(dǎo)”;完善獨(dú)立董事會制度,發(fā)揮獨(dú)立董事監(jiān)督作用;加強(qiáng)對信息披露工作的管理。
[Abstract]:In the stock market, investors use the information disclosure of listed companies to make investment decisions, because of the information asymmetry, the managers of listed companies dominate the information superiority, and the external shareholders in information disadvantage, information disclosure is prone to information distortion, financial fraud, speculation and other defects, which seriously damage the interests of investors, affect the enterprise lasting health development. There is an urgent requirement to find the factors affecting the quality of the information disclosure, and improve the governance of the board of directors is the key factor to improve the information disclosure quality, therefore, how to strengthen the governance of the board of directors to improve the quality of information disclosure is the problem to be solved.
At present, the domestic and foreign existing literature is to study the relationship between corporate governance and the quality of information disclosure, to study the characteristics of the board of directors or only selected individual factors, and this paper directly from the board governance perspective, based on the efficient market theory, information asymmetry theory and the principal-agent theory, put forward the research hypothesis, the empirical relationship between the board of directors governance and the quality of information disclosure.
