摘要
内部人减持一直是市场关注的焦点,由此产生的市场波动和财富转移更是引发社会各界的广泛热议。出于保护投资者权益、维护市场稳定的需要,有关部门出台相应法律法规来监管内部人减持,虽有成效,但问题仍旧严重。为此,本文立足我国融资融券制度实施这一标志性事件,尝试探寻一种市场化的治理机制,为监管内部人减持提供新的视角。研究发现:融资融券制度的实施能够显著抑制内部人的减持行为,且具有较高的经济显著性。在经过一系列稳健性测试后,该结论依然成立。机制检验证实,融资融券制度会通过增大内部人减持成本和降低内部人自利倾向,对内部人减持产生抑制作用。进一步研究发现,该制度在治理清仓式减持方面具有显著效果,且不同的市场行情并不会影响该制度治理效应的发挥。在区分减持动机的检验中发现,融资融券制度一方面会对自利动机的减持行为产生显著的治理作用,而另一方面也可能制约一些非自利的减持活动。此外,本文发现该制度在减持大年依然具有显著的治理效果。综上表明,融资融券制度是一种有效应对内部人减持的市场化治理机制,这为进一步深化金融改革、完善资本市场交易体系提供了证据支持,也对国家在优化减持制度方面具有一定的启示意义和参考价值。
