T test and Wald test results show that price model is better than return model to study on value relevance in china’s emerging market. Results reveals cash flow value relevance has been improved and has higher incremental information content on earning since 2002 by annual test.Based on the results above, chapter 6 investigates quality of accounting information represents by information disclosure quality.
