中文摘要：

在充分梳理国内外在职消费研究文献的基础上，以内部控制对于上市公司超额在职消费的抑制作用为主要研究目标，从外部政策变化视角入手，即借助限薪令和八项规定的颁布，利用厦门大学内部控制指数（2007-2014），区分国有与非国有上市公司，对我国2007-2014年非金融上市公司内部控制和超额在职消费的关系进行了研究。结果发现，高质量的内部控制显著降低上市公司超额在职消费程度，运用工具变量控制内生性之后，上述结论依然稳健，而且，国有上市公司中内部控制对于超额在职消费的抑制作用更为明显；分别对2009年限薪令出台的前后情况、2012年八项规定出台的前后情况进行了研究，发现政策生效后内部控制对国有上市公司超额在职消费的抑制作用更加明显。
