The Empirical Study of that Non-recurring Gains and Losses Affect the Quality of Listed Companies-On the Basis of XBRL Files of Shanghai Listed Companies in 2010

Non-recurring gains and losses is a very important factor which influences the quality of a firm's profit. This paper uses last year's financial data of 700 Shanghai listed companies in empirical study to analyze how the quality of profit is influenced by Non-recurring gains and losses. By analyzing, Non-recurring gains and losses have a large percent of the listed companies' profit of 2010, which is up to -2795.97%-8734.73% of total profit. Most part of firms' recurring is still main source of their profit. However, we can know that some listed firms use Non-recurring gains and losses to revise profit from the analysis. On the basis of this study, we advise that we should regard the Non-recurring gains and losses as a independent content in the Profit Statements and publish it in details; in the meanwhile, we suggest that take the effects of Non-recurring gains and losses into consideration in the policies implementation in order to provide high-quality accounting messages.
