本文采用1999--2003年间上市公司的数据,在分析我国企业资本结构决定因素的基础上,对多元化与资本结构的关系进行了研究。我们的研究表明,所有权性质对我国企业多元化与资本结构的关系有着显著的影响:对于国有控股企业,多元化会造成其财务杠杆的显著提高;对于非国有控股企业,这种影响并不显著。多元化动机的差异可能是造成这种现象的原因。共同保险理论可以解释国有控股企业资本结构的显著改变;对于非国有控股企业,我们没有发现内部资本市场失效的证据。
In this paper, we focus on the relationship between corporate diversification and capital structure. Our research shows that ownership makes a marked impact on this relationship: diversification raises the leverage of state-controlled enterprises significantly, while it's not the case for non-state-controlled companies. The coinsurance effect can explain why the state-controlled companies diversify, and we do not find any proof on the ineffectiveness of internal capital market of non-state-controlled companies.
