摘 要:现代资本结构理论从20世纪50年代中后期开始独立成为现代经济学的一个重要的研究领域。在资本结构规范研究基础上，中外学者对资本结构进行了广泛的实证研究。本文在前人研究基础上，主要对我国首次在深圳证券交易所创业板上市的28家公司的2010年到2012年连续三年的资本结构进行分析，发现创业板首批上市的28家公司存在逆优序融资现象。该现象产生的原因是，创业板上市公司债务融资困难和创业板上市公司缺乏正确的融资观念。针对这一现象本文提出了适当提高资产负债率，发挥财务杠杆作用、适当提高资产负债率，发挥税盾效应、适度增加长期负债，优化企业负债结构、树立创业板上市公司理性融资观念和政府减少对金融市场干预，扩宽企业融资渠道的建议，从而优化创业板上市公司资本结构。
