《萨班斯法案》对美国公司董事会影响的分析

2002年度美国出台的《萨班斯法案》全方位地对安然等事件暴露出来的问题作出相应的调整性规定,必将对公司治理产生深切的影响。《萨班斯法案》对审计委员会提出了修正性和提高性要求,本文选择外部董事、女性董事、财务专家、CEO兼任董事会主席、CEO在提名委员会任职等指标进行分析。实证分析结果说明：《萨班斯法案》有效消除了董事会和管理层任人唯亲的现象,董事会的独立性和专业性均有所提高。其实,《萨班斯法案》颁布之前就有加强公司治理的要求,公司治理就有改进的趋势,但《萨班斯法案》关于审计委员会方面的明文规定加速了公司董事会的变化,使得公司治理改革超越了法律的既定要求。
