Abstract: 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.
