A + H股交叉上市对会计信息质量的影响研究

Abstract

文本以1998~2014年之间共17年的A + H股交叉上市的公司为研究样本，并在A股上市公司中选取可比较的匹配样本，采用一对多的样本匹配方法，探讨两者间的会计信息质量差异。通过描述性统计和方差分析发现A + H股交叉上市公司的会计信息质量好于A股上市公司的会计信息质量，新会计准则的颁布，加大了A + H股交叉上市公司和A股上市公司之间会计信息质量的差异。 This paper selected A + H shares cross-listed companies and only A-shares listed companies from 1998 to 2014 as samples. Based on the samples, the quality of accounting information of those was empirically researched by the one-to-many sample matching method. By means comparison and variance analysis, it proved that A + H shares cross-listed company’s accounting information quality was better than only A-shares listed companies. After the implementation of the new accounting standards in 2007, the difference in the quality of accounting information between the A + H shares cross-listed companies and the A-shares companies significantly changed; the disparity of the quality was enlarged.
