所得税率、所有权性质与债务结构

Corporate Income Tax Rate,Ownership and Debt Structure

本文研究所得税率对公司债务结构的影响,并考察这种影响在国有控股公司和非国有控股公司之间的差异。研究发现:税率越高,公司有息债务占总负债的比例就越高,并且这种关系在国有控股公司中更加明显;税率越高,公司有息债务中长期债务的比例就越高,并且这种关系在非国有控股公司中更加明显。上述证据表明公司的确会因利息的税盾作用而调整债务结构,但是所有权属性不同的公司,由于其面临的融资环境不同,利用债务税盾作用方面存在一定的差异。本文丰富和深化了税收与资本结构方面的研究,可以增进我们关于不同产权类型企业财务决策行为差异的认识。
