Fama and French(1993)提出的三因素模型对许多国家的股市收益率有良好的解释力并得到广泛应用。我们在三因素模型的基础上,利用分位数回归技术全面考察三因素对上证行业指数收益率的影响。实证结果表明:(1)在各个分位点上,市场因子对...Fama and French(1993)提出的三因素模型对许多国家的股市收益率有良好的解释力并得到广泛应用。我们在三因素模型的基础上,利用分位数回归技术全面考察三因素对上证行业指数收益率的影响。实证结果表明:(1)在各个分位点上,市场因子对五类行业指数均有显著的正向影响;(2)规模因子对五个行业指数的影响方向不同,其中对综合指数和地产指数具有显著的负向影响,而对其他三类指数具有显著的正向影响;(3)账面市值因子对五个行业指数的影响方向也不同,其中对综合指数和公用指数具有负向影响,对工业指数和商业指数具有正向影响,对地产指数既有正向影响又有负向影响,同时在部分分位点上,账面市值因子对五个行业指数的影响不显著。展开更多
