The Impact and Its Performing Mechanism of Divestiture on Financial Performance
-
摘要: 以2008—2017年我国A股上市公司为研究样本, 实证检验了资产剥离对企业财务绩效的影响及其作用机制。研究发现, 资产剥离的实施能够显著影响企业的财务绩效, 其对企业财务绩效的作用方向取决于剥离前企业的业绩基础, 即对于经营不佳的企业而言, 资产剥离损害了企业财务绩效, 反之则显著提升了企业财务绩效。机制检验表明, 融资约束在资产剥离与企业财务绩效的负向关系中发挥了中介效应, 投资效率在资产剥离与企业财务绩效的正向关系中发挥了中介效应。Abstract: Using a unique sample constituted by the 2008-2017 A-share listed companies in China, this paper empirically tests the impact of divestitures on corporate financial performance. It is found that the implementation of asset divestiture can significantly improve the financial performance of enterprises, the influence of divestitures depends on the prior performance of the companies. Divestitures can significantly improves the financial performance of higher-performing companies, and vice versa. The findings from mechanism research indicate that financing constraints and investment efficiency play an intermediary role in the negative and positive relationship respectively between divestiture and corporate financial performance.
