异常派现对投资效率影响研究——基于中国上市公司的经验证据

The Effect of Abnomal Dividend on Investment Efficency Evidenced by Data from China Listed Companies

关于现金股利与投资效率关系的研究大都停留在正常派现层面上,而异常派现与投资效率的关系,以及自由现金流在异常派现与非效率投资之间所扮演的角色是一个值得深入研究的问题。本文通过对2010～2013年上市公司异常派现对非效率投资以及通过自由现金流对非效率投资的影响进行了检验。基准模型的结果表明:异常高派现对过度投资具有抑制作用,并导致投资不足;异常低派现与过度投资具有正向显著关系,与投资不足显著负相关。加入现金流交乘项后发现:异常高派现仅对现金流缺乏的上市公司过度投资具有抑制作用,而对于自由现金流丰富的上市公司而言,异常高派现并没有对过度投资产生抑制作用。本文的研究结论丰富了对现金股利政策与投资效率关系的认识,并为上市公司异常派现下的投资效率的改善和提高提供实证支持。
