摘要
差异化征收红利税是我国资本市场制度建设的新尝试。为了研究差异化红利税的政策效果,本文选取2005年6月14日-2014年8月13日期间A股市场发生的7927次纯现金分红作为样本,采用事件研究法和回归分析,发现:(1)政策实施后,除息日异常收益率显著增大,投资者对现金分红的偏好减弱,实际红利税负加重;(2)除息日前后的异常交易量显著增大;(3)股价波动率显著增大。差异化红利税政策没有起到抑制投机的作用。

In order to study the effect of differentiated dividend tax, we employ the event study method and regression analysis, basing upon 7927 pure cash dividend events in the A - share market between June 14th, 2005 and August 13th, 2014, find that (1) after implementation of the policy, the abnormal return on the ex - day significantly increases, investors' preference for cash dividend is weakened and the real dividend tax burden increases; (2) the abnormal trading volume around the ex -day significantly increases; (3) the stock return volatility around the ex -day significantly increases.
