中文摘要：

基于2010~2013年沪深A股上市公司数据,实证分析了内部控制效率对资本结构调整速度以及资本结构偏离度的影响,并验证了内部控制是否通过优化资本结构的动态调整过程而提升了公司价值。研究发现：内部控制水平越高的公司,资本结构调整的速度越快、实际资本结构偏离目标结构的程度也就越低;内部控制的上述作用在激进的资本结构情况下表现得更强亦更显著;资本结构动态调整在内部控制与公司价值的关系间发挥了显著的部分中介效应。

英文摘要：

Using samples of Shanghai and Shenzhen A-shares listed firms in 2010-2013, the paper empirically investigates the influence of internal control on capital structure adjustment speed and deviation degree, and analyzes whether internal control enhanced firm value by influence on dynamic capital structure. The study finds that, the speed of capital structure adjustment will be up and the deviation degree of capital structure adjustment will be down when the level of internal control is better, and that effect is more strong and significant in aggressive capital structure. The dynamic adjustment of capital structure plays significant partial mediating effects in the relation between internal control and firm value.
