摘要:本文利用2011-2016年间我国沪深两市A股上市公司的面板数据,考察了我国不同行业现金股利政策与股票价格波动的关系。实证结果表明,除电力、热力、燃气及水生产和供应业外,以股利收益率为代理变量的现金股利政策对我国沪深A股不同行业上市公司的股价波动都具有解释能力。股利收益率与股价波动呈负相关,表明分红政策能够显著降低股价波动水平,其中这种影响在采矿业表现最强,房地产业次之。因此,为了促进我国沪深股票市场健康稳定发展,现金股利政策是必不可少的工具之一,政府监管部门、上市公司和投资者,应根据不同行业的具体情况,合理选择恰当的现金股利政策实施方式和力度。
Abstract: Based on Panel Date Analysis method, the paper empirically analyzes the relationship between cash dividend policy and stocks' volatility in different industry sectors with a sample of the stocks listed in Chinese A-share Exchange during 2011-2016. The results show that cash dividend policy (dividend yield) does affect the stocks' volatility in Chinese A-share Stock Exchange. Especially, stocks' volatility is negatively correlated with dividend yield, that is to say, the increase of cash dividend may decrease stocks' volatility, and this kind of influence will be strongest in Mining Industry and then in real estate industry. Therefore, the dividend policy will be one of the most important tools to promote the healthy and stable development of stock market, the government regulators, listed companies and investors should select the appropriate dividend policy mode and strength according to the specific conditions of different industries.

现金股利是上市公司回报股东的重要方式,成熟资本市场体系中,更是被视为投资者股权投资最主要的收益来源。在我国,经过二十多年的迅速发展,资本市场取得的成就举世瞩目,但在现金股利问题上,与西方国家市场的差距却有目共睹。近年来,随着监管层的日益重视,以及投资者素质的逐步提高,我国A股市场上市公司现金股利的比例和幅度已经有所改善,但长期不分红、少分红的现象仍普遍存在。对此,陈雨露、汪昌云[1]和彭志胜、宋福铁等[2]学者认为,国内外上市公司在现金股利分配的数量、形式、及时间上的显著差异,很可能正是造成我国股票市场股价波动较大现象的原因之一。……
