摘要
本文实证研究了融资融券对我国上市公司创新数量与质量的影响。为克服模型的内生性,首先采用倾向分数法为每个标的公司按照一比一的比例进行配对,然后再构建双重差分模型。本文发现融券促进了创新数量与质量的同步增加,而融资却导致创新数量与质量同步下降。在融资交易为主的情况下,融资的负面影响超过了融券的正面影响,从而使得融资融券总体上阻碍了企业创新。在控制了配对偏差和所有权性质差异影响、采用其他创新替代变量以及更长事件窗口的情况下,上述结论依旧成立。进一步研究发现,融资融券影响企业创新的机制不仅包括公司治理机制,还包括信息机制。面对融资融券的复杂影响,标的公司倾向于采取"重申请数量轻质量"的创新策略进行应对,最终导致其创新质量明显下降。
