本文以我国上市公司2001至2004年的面板数据为研究样本,从会计信息系统和组织结构复杂性两个维度,建立了一套客观反映我国上市公司综合透明度水平的评价指标体系,并在此基础上,考察公司透明度对股价波动同步性的影响。实证结果表明,公司的会计信息透明度和组织结构透明度越低,股票价格所反映出的公司特质信息的含量越低,股价波动的同步性越强。这一研究结果不仅支持了股价波动的信息含量差异源于公司透明度差异的论点,而且拓展了有关公司透明度的研究,对更加深入且全面地理解公司透明度的经济后果有着重要的启示作用。
Based on a panel data of Chinese listed firms during 2001-2004, this paper develops a set of corporate transparency index from two dimension which are aceonnting information system and organizational structure complexity, and empirically tests the relation between the corporate transparency and the synchronicity of stock price variation. The results indicate that, the more the accounting transparency and organization transparency are, the more synchronlcity of stock price variation is. This research not only supports the argument that the difference among corporate transparency leads to the different synchronicity of stock price variation, but also inspires to deeply and comprehensively understand the economic consequence of corporate transparency.
