中文摘要:Modigliani 和Miller提出现代资本结构的基石——MM理论以来,国内外经济学家对资本结构这个问题进行了大量的研究。各种理论不断出现,以优序融资理论、代理成本理论、财务契约理论和信号理论等为代表的理论把资本结构理论推向顶峰,但是,到目前为止,没有人敢说已经解决了“资本结构之谜”。 我国现有的相关文献主要关注的是资本结构的影响因素,但是专门研究资本结构和公司业绩之间关系的文献并不多见,而且在研究二者之间的关系时,采用的也大多是单方程模型,应用普通最小二乘回归的方法进行研究。但是,本文认为,资本结构和公司业绩之间是互相影响的,因此采用联立方程的形式来研究资本结构和公司业绩之间的相互影响关系。另外,为了消除行业的影响,本章选择了零售行业50多家上市公司的数据作为研究对象。 本文以资产负债率作为衡量资本结构的指标,以总资产收益率和净资产收益率作为衡量公司业绩的指标。从国内外的文献回顾和相关资本结构的理论中可以看出,国内外经济学家并没有对资本结构和公司业绩之间的关系达成一致的看法。因此有必要对此进行进一步的研究。 本文运用非参数检验和联立方程回归模型的方法研究资本结构和公司业绩的关系。 在非参数检验部分,首先考虑资本结构对公司业绩的影响,分别用理论概括和非参数检验的方法进行了研究;然后反过来对考虑公司业绩对资本结构的影响,也对此进行了理论概括和非参数检验,得出的结论是资本结构和总资产收益率之间正相关,和净资产收益率之间的相关性不是很明显。 在联立方程检验部分,采用两阶段最小二乘法研究了资本结构和公司业绩之间的相互影响关系,并与普通最小二乘回归结果进行了比较,得出和上述非参数检验相一致的结论,即资本结构和总资产收益率显著负相关,但是和净资产收益率没有显著的相关关系。 文章最后根据研究结果对我国上市公司提出了相关的对策和建议。包括:优化公司资本结构、完善公司的治理结构等。  
英文摘要:Since Modigliani and Miller first proposed their theory on capital structure, the foundation of modern capital structure theory, the economists have done a lot of researches on the issue of the capital structure and have gained many fruits. But so far none can say that he has solved the problem. The past study has showed that the choices of the capital structure are affected by many factors. But there are not many people who have studied capital structure and business performance. And the methods that they used are not practical .This thesis offers thorough empirical analysis study of the correlations between China's 50 retailing listed companies' capital structure their performance. We use LA to measure the capital structure, and use ROI and ROE to measure business performance. We can see from the theory and the results gained that there are not the same conclusions about the relations between the capital structure and business performance. So we should study them further. This thesis use empirical analysis to study the correlations between capital structure and business performance. Brief introduction of the data resource, variables, model selection and their significance are made. Followed it is data analysis and conclusions. Variables are valued through statistics analysis and the correlation between capital structural and companies' performance is deducted. At last the thesis gives us the results of the model's result. The LA has strong relationship with ROI, but no relationship with ROE. Cause of this relationship between the two factors are explained through the analysis of domestic listed companies' management structure as well as the equity and liabilities' influence in the management structure.
