摘要：作为债的保全制度之一的债权人代位权制度起源于罗马法，各国的立法对代位权制度的规定也不尽相同。文章认为，我们应当通过比较和研究的方法先以理论的形式对代位权制度做一个总的概述，然后通过案例的途径来探索与寻找实践过程中潜在的问题。随后与传统民法中的“入库规则”比较，进而分析我国现存代位权制度中的优先受偿规则以及关于代位权诉讼中另行起诉的规定是否合理，最后提出解决实践中问题的方法和完善该制度理论的畅想。本文以强调“债的平等性”原则的重要性为主线，认为“债的平等性”原则对于完善代位权制度构成要件、代位诉讼以及代位执行程序等方面实现真正意义上的公平公正有着积极的意义，而我国的债权人代位权制度的局限性在于片面地倾向于实现债权人的优先受偿。这样的规定构成了对传统"入库规则"的悖离，同时对于“三角债”和多数人的债权债务纠纷问题的解决也起不到实质性的作用。

Abstract：As the debt preservation system of the creditor's right of subrogation system originated from Rome law, the legislation on the right of subrogation provisions are not the same. I think we should compare and research methods in theory in the form of the system of right of subrogation do an overview, and then through the case approach to explore and find the potential problem in the process of practice. Subsequently with the traditional civil law" rule of warehousing" comparison, and analysis of China's existing system of right of subrogation in the rule of priority of claim and the system of subrogation right separately sued the rule is reasonable, finally put forward to solve the problem in practice method and improve the system theory of the imagination. In this paper, in order to emphasize " the equality of credit" principle importance as the main line, that " the equality of credit" principle to improve the system of right of subrogation constitution, subrogation and subrogation performance procedures, to achieve a real sense of fairness and justice has a positive meaning, but in China the creditor's right of subrogation system limitation is one-sided tendency to realize the creditor priority. That regulations constitute the traditional" rule of warehousing" deviations, while" trigonometry debt" and the majority of the debt disputes resolution is also not a substantive role.
