摘 要
由于“国海”事件,“债券代持”这一行业潜规则再次频频出现在近期的新闻报道中。“债券代持”是指在不转移实质所有权的情形下,请他人代其持有债券的业务。它并非标准金融术语,而是一项由市场自发形成,目前处于灰色地带的业务。
考虑到债券代持缺乏学术上的鉴定,本文从质性研究的方法入手,通过扎根理论归纳出“代持动机”、“抽屉协议”、“风险敞口”、“财务绩效”四个主范畴用以更好地理解和阐述债券代持产生的原因、连接持代双方的枢纽、风险驱动因素以及为企业带来的影响。接下来,针对扎根分析得到的各主范畴,本文归纳出了持代双方所存在的风险敞口。
根据“抽屉协议”的不完全性,并据此构建动态博弈模型分析影响持代双方行为(特别是影响持有方违约)的因素,得到债券实际亏损及对回表产生的绩效压力是导致违约的关键因素,结合债券代持本身存在的风险敞口,将敞口的思想与熵权法结合测度从事代持业务的金融企业的财务风险,利用EVA表示企业的财务绩效,并依据证监会发布的资本市场上32家金融企业2011年至2015年的代持数额、风险测度指数同财务绩效指数进行实证分析,验证前者同后者的相关性。最后,依据实证分析的结果对企业选择债券代持业务中需要考量的因素提出合理化的建议。
本文的创新点在于:首次利用扎根分析发掘了债券代持中各主要范畴,并且依据不完全信息博弈的理论简化持代双方博弈过程,分析了导致违约敞口的因素。构建的财务风险测度模型中结合了熵权理论以及敞口的思想,并将其运用到从事债券代持的金融企业的风险测度上。
本文的研究成果预期对于债券代持为企业带来的风险敞口存在一定的解释作用,对于企业在债券代持中应衡量的方面具有一定的理论指导意义。

Abstract
As a result of the "Guo Hai" incident, "Agent-bond-holding" appeared frequently in the recent news coverage once again. This transaction means searching for others to hold enterprises’own bond on the behalf of them, but credited as a trading business to the balance sheet. It is not a standard financial terminology, but a spontaneous formation created by the market, which is currently belong to the gray area.
Considering the absence of definition academically, this thesis starts from the method of qualitative research. In order to understand and explain this transaction deeply, this thesis summarizes the four main categories of "acting motive", "drawer agreement", "risk exposure" and "financial performance" through grounded theory. Then, this thesis analyzes the risk exposures of holders and holdees respectively.
Based on incompleteness of the "drawer agreement", it constructs the model of dynamic game to explore the factors that affect the behavior of the holders and holdees in basic of incomplete information. According to the analysis mentioned above, the real drivers that lead to the breach of the contract come from the actual loss of the bond. Furtherly, this thesis elaborates potential risks and evaluates the financial risk of specific companies by combining the idea of risk exposure and entropy weight. Besides, sample data of empirical analysis come form 32 financial concerns of capital market published by CSRC during the period of 2011 and 2015. In this part, this thesis verifies the correlation between the amount of bond-holdings, the situation of financial risk and the level of financial performance of sample enterprises, which is presented by EVA. Finally, this thesis provides reasonable suggestions on what should be considered when a company choose this transaction.
The innovation of this thesis lies in the following aspects: It firstly uses the grounded theory to define " Agent-bond-holding ". Then, the game process of holders and holdees is simplified by model of incomplete information dynamic game, analyzing the factors that lead to nonperformance. Moreover, the model measuring financial risk constructed in this thesis combines entropy theory and the idea of risk exposure, which is applied to the risk measurement of financial enterprises engaged in this transaction.
This thesis is expected to be helpful for widely explaining the risk exposure provided by " Agent bond holding " and giving theoretical advice for the enterprises when they decide to engage in this transaction.
Key words: Agent-bond-holding;Risk exposure; Performance Evaluation;Empirical Analysis
