摘要:

代理成本和信息不对称是导致公司出现融资约束的重要原因。本文以2010年3月正式推出的融资融券制度为外生冲击,以2005—2015年间沪深两市A股非金融类上市公司为研究样本,利用双重差分(differenceindifference)模型实证检验了卖空压力对公司融资约束的影响。本文研究发现:(1)卖空压力能够提高公司银行贷款规模,降低贷款成本;(2)卖空压力能够降低公司的现金持有水平;(3)卖空压力能够降低公司的现金—现金流敏感性。综合来看,卖空压力能够缓解公司融资约束。进一步的,卖空压力对公司融资约束的缓解作用在民营企业中更加显著,并且卖空压力可能是通过降低公司代理成本和信息不对称程度进而缓解融资约束的。在各种稳健性检验后,本文研究结论保持不变。

Abstract:

Agency cost and information asymmetry are two of the most important reasons leading to the financial constraints faced by firms. Based on the pilot “margin trading, short selling” program in China, this paper investigates the relationship between short selling pressure and corporate financial constraints with the differenceindifference model, using listed companies data of Chinas Ashare markets from 2005 to 2015. It finds that short selling pressure can significantly reduce the financial constraints of the companies which are eligible to the pilot program. In addition, the negative relationship between short selling pressure and corporate financial constraints is much stronger among nonSOEs. Furthermore, we find that short selling pressure will mitigate financial constraints may through agency cost and information asymmetry channels. The empirical results remain unchanged when using different kinds of robust checks.
