中文摘要:以价格模型为基础,选取中国沪深两市A股非金融上市公司为样本,研究了新会计准则实施前后利润表新增项目(即公允价值变动收益项目与资产减值损失项目)的价值相关性。结果发现,新准则实施后利润表的价值相关性显著提高。进一步研究发现,资产减值损失项目价值相关性较强,相比旧制度下信息质量也得到改善,但不是信息增量的主要来源;而公允价值变动收益项目信息并未得到市场显著反应。结果表明,利润表中其他项目质量的改善是会计信息价值相关性增加的主要源泉。

Research on Value Relevance of Newly Formulated Items in Income Statements under New Accounting Standards——The Empirical Evidence from Chinese Non financial A share Listed Companies
Abstract:y the price model, taking the non financial companies in A share stock market as sample, the value relevance has been analyzed on the new items in the income statement under New Accounting Standards (NAS). It is found that the value relevence has increased significantly since the implement of NAS. Further investigations demonstrate that, Losses on Impairment of Assets has more value relevance than Gains from Changes in Fair Value has. Compared to the old Accounting Standards, the information quality of Losses on Impairment of Assets has been improved. Information increments of value relevance mainly come from other traditional items, not from Losses on Impairment of Assets. The item of Gains from Changes in Fair Value has not received a significant market reaction for investors comparatively.
