我国信用评级业的发展状况研究 ----基于信用评级对我国债券市场的影响分析 内容摘要 近年来,我国债券市场发展迅速。我国的债券总量得到了极大的提高,债券种类也得到了很大的丰富。但是,其中的企业债所占份额还是太少.我国企业的债券融资渠道还没有很好的发挥。要发展好我国的企业债市场,最重要的一个方面是发展和完善我国的信用评级市场。 在当前的市场经济环境中，信用是经济和金融体系中最为基础和核心的因素，这一现象在债券市场中表现得更为明显。首先，债券市场的存在本身就是以信用存在为前提的；其次，在完善的债券市场中，发债主体信用度的高低决定了其债券能否被市场接受，而债券本身的信用等级更是决定了债券的价格和发行的模式。从这个角度上说,完善的信用评级业对我国债券市场的发展至关重要。 然而,我国的信用评级业还处于起步阶段,在债券评级业上,还存在很多问题。由于我国企业债券具有准国债的性质,使得债券的利率发生了扭曲,尽管企业进行了评级,但不同的评级结果仍按同一债券利率发行。评级成了一种资格审查,利率由政府确定。这就启发我们思考,我国的信用评级业发展现状如何,其对债券市场的影响程度如何。这就是本文研究的核心内容。 文章通过介绍国内外已有的研究成果,对我国信用评级市场的现状和问题进行了定性和定量分析。在定量研究中,文章运用了真实利息成本模型和事件研究模型,发现不论是在企业债券的一级市场还是二级市场,我国信用评级都有一定的影响力。最后,针对存在的问题,文章提出了发展我国信用评级业的政策建议。 关键词:信用评级 债券评级 发行成本 收益率 ABSTRACT These years, our country’s bond markets have been developing quickly. The total of our bonds has increased a lot, and the types have been greatly enriched. However, the share of corporate bond is still too small. The financial channel of corporate bond isn’t well developed. And one of the most important aspects to develop corporate bond market is to improve our credit ratings market. In the current market environment, credit is the core of economy and financial system. This phenomenon is far more apparent in bond markets. First, the bond markets are based on credit; Second, in perfect bond markets, the credit degree of the issuers determines the acceptance of their bonds, and the bonds’ credit rating themselves determine their prices and issuing patterns. In this point, improving our credit rating industry is vital to the development of our country’s bond market. However, Chinese credit rating industry is still in its infancy period. There are also many problems in the bond rating industry. As quasi-government bonds, corporate bonds’ interest rates have been controlled. Although companies are rated, the companies having different credit rating issue bonds at the same interest rate. Bond ratings become a test of qualification, interest rate is determined by the Government. This inspires us
