近年来的研究发现,公司所处的良好外部制度环境有助于提升公司的价值。论文聚焦公司内部制度环境,使用厦门大学内控指数课题组构建的2007—2009年我国上市公司内部控制指数,研究了内部控制对公司价值的影响。研究发现:(1)内部控制的改善有助于提升公司的价值,并且内部控制的改善能够减轻政府控制对公司价值造成的负面影响(相对于非政府控制的公司);(2)内部控制的变化对公司价值变化的影响逐渐减弱,尽管政府控制能缓和这种递减的趋势;(3)当公司所面临的外部制度环境较好时,内部控制的改善对公司价值的提升作用更加明显。研究建议监管机构应进一步推进我国上市公司的内部控制建设。
Prior studies document that external institutional environment helps enhance firm val- ue. Using the internal control index(Cindex) developed by a research group from Xiamen Univer- sity as our proxy for internal control quality, we examine how internal control affects firm value. We find that.. ( 1 ) firm value increases with the improvement of internal control quality and better inter- nal control can mitigate the negative effect of state ownership on firm value( compared to non- state-owned listed firms) ; (2) changes in internal control quality have a decreasing influence on changes in firm value, although state ownership moderates this decreasing trend; and(3) the positive association between internal control quality and firm value is more salient when the exter- nal institutional environment is well developed. Our study suggests that regulatory bodies should further promote and advance the development of internal control systems for Chinese listed firms.
