| 摘 要： | 信息含量表示会计盈余与股票回报之间的关系。本文利用事件研究法检验1995—2000年间中国A、B股会计盈余的信息含量,结果发现中国A、B股市间盈余数字的信息含量存在很大差异,其中B股市场明显高于A股市场。我们认为造成这一差异的原因在于我国股市的“硬分割”阻碍了投资者对信息的传递、评价和反应,进而导致A、B股市场出现“软分割”现象。

| Abstract: | The information content means the relation between accounting earnings and the stock return.This paper makes use of the event research method to examine the information content of an accounting earnings of both A and B stock market in 1995-2000.As a result,We find that there is a very big difference between A stock market and B stock market about the information content of accounting content.The B stock market's accounting content is obviously high in that of A stock market.We think that the reason of this difference lies in "hard segment" of the our country stock market,which obstructs investors to deliver,evaluate and respond to the information,then causing "soft segment" between both A stock market and B stock market. |
