我國上市公司綜合收益信息有用性研究
[Abstract]:The Ministry of Finance issued the Accounting Standards for Enterprises interpretation No. 3 in 2009, proposing to add "other comprehensive income" and "integrated income" items to the income statement, and requiring detailed disclosure of other composite income components items in the notes. This marks the change from the traditional income model to the comprehensive income model in China's enterprise accounting standards. Based on the 2009 annual report data of A-share listed companies in Shanghai and Shenzhen stock markets, this paper empirically tests the usefulness of comprehensive income under the new accounting standards by using price model and earnings stock return model. Different from previous studies, this paper studies the usefulness of comprehensive income, not only to investigate the value correlation of comprehensive income, but also to increase the robustness of comprehensive income. The main conclusions of this paper are as follows: (1) there is a significant correlation between net profit and combined income, and the value correlation of comprehensive return is lower than that of net profit. This is due to the combination of the composition of other integrated income items that offset each other. When the other comprehensive returns are added to the model, the influence of net profit on the stock price is increased, and there is also a significant correlation between the other composite returns and the stock price. (2) in other detailed items of comprehensive income, only the influence of the change of other owners' equity under the EPS method and the profit and loss caused by the per share cash flow arbitrage tool have significant correlation with the stock price. Other detailed items are not significantly related to the share price. (3) in the price model, the company size, the current ratio and the tradable share ratio are all entered into the model, and the current ratio is proportional to the stock price, while the company size and the tradable share ratio are negatively correlated with the stock price. (4) the bad news of accounting earnings recognition of net profit and comprehensive income has incremental timeliness compared with good news, that is, both of them have conservatism, but not significant, and the level of soundness of comprehensive income is lower than that of net profit. Since the testing of other comprehensive return breakdown items makes us realize the importance of other comprehensive return detail items, the overall reflection of the composite return can only offset the impact of the detailed items on the stock price, while the composite return contains high risks. Uncertain gains and losses also make it less robust, so this paper hopes to remind investors to pay more attention to the detailed items of other comprehensive returns, and suggest enterprises to enhance disclosure of other comprehensive returns. In order to reduce managers' earnings management space, highlight the transparency of corporate performance.
