内部资本市场价值、形成路径与投资者市场反应

选取中国制造业上市公司作为样本,在计量其内部资本市场价值的基础上,通过通径模型找出内部资本市场价值的形成路径,然后计算年报披露后不同时间窗口的累计超额收益率,分析投资者对内部资本市场价值的市场反应,揭示投资者市场反应机制对内部资本市场行为的治理作用.研究结果表明,上市公司的权益报酬率是决定其内部资本市场价值的最主要因素;权益报酬率与内部资本市场价值之间呈反向关系,内部资本市场价值主要存在于低权益报酬率企业,表明中国上市公司的内部资本市场价值主要源于缓解外部融资约束而引起的溢价,而不是由资源优化配置产生;由于投资者对内部资本市场价值反应不充分,内部资本市场缺乏投资者反应机制的治理,内部资本市场功能异化为弥补资金漏洞的工具.
