| 中文摘要: | 二十世纪六十年代初,哈佛大学Donaldson教授发现优序融资问题,即企业在融资过程中存在偏好内部融资,如果需要外部融资,企业首先发行债券,最后不得已才是发行股票。很多理论被提出来解释企业的优序融资问题,其中绝大多数相关研究都隐含地假定管理者和投资者是效用最大化的理性决策者。但是很多心理学和经济学研究已经表明,人们普遍存在过度自信和过度乐观等非理性特征。 越来越多的管理者存在过度自信。过度自信的管理者认为资本市场低估了公司发行的有价证券,一般来说股票的风险比债券更大,因此他认为股票被低估的程度大于债券被低估的程度,所以过度自信的管理者就会选择发行债券而不是发行股票。 本文通过对我国2006年和2007年沪深两市A股市场的上市公司融资行为进行实证分析,发现我国上市公司的管理者普遍存在过度自信,且这种心理因素与企业的优序融资行为显著相关。实证研究表明,企业的外部融资中债务融资的比例与管理者过度自信显著正相关,债务融资中短期融资比例也与管理者过度自信显著正相关。本文还分别对2006年和2007年的数据进行了回归分析,得到了相同的结论。 本文从行为融资理论角度对优序融资问题做出解释。行为融资理论与传统的融资理论的差别在于“非理性因素”的引入,本文抛弃“理性经济人”假设,研究了管理者过度自信对企业融资行为的影响,从行为金融学角度解释了上市公司的优序融资问题,为优序融资问题提供了新的视角,进一步丰富了优序融资理论。 | |
| 英文摘要: | Professor Donaldson developed the pecking order in the lata of 1960. A firm’s financing order is retained earnings, debt and equity. There are many theories to explain the pecking order. These theories all base on the hypothesis which is managers and investors are rational.But that is not true.Many researchs on psychology and Economics suggest that most of persons are overconfident. More and more managers are overconfident.Overconfident managers believe the value of the security is underestimated, and the equity has more risk than the debt, so they pefer to choose the debt finaning. This paper uses the listed company in 2006 and 2007 as samples,finds that most of managers in the listed company are overconfident,and this influnces the finaning behavior strongly.The result indicates that the degree of confident of managers is relevant positively to the ratio of the debt finaning,and also relevant positively to the ratio of short-term debt finaning. This paper tries to explain the pecking order,based on Behavioral Corporate Financing Theory.Major difference between the behavioral financing theory and traditional financing theory is the introduction of “irrational factors”.This paper abandons the hypothesis of rational people,makes research on how overconfident managers make financing desidions ,tries to explain the pecking order on listing company with the behavioral financing theory.It opens the Behavioral Corporate Financing Theory,and explains the pecking order from a new prospect. | |
