债权人代位权诉讼制度涉及到三方主体和两层法律关系，因其不同于普通诉讼的复杂性，在司法实践的运用中产生了许多争议问题。之前许多学者都将代位权诉讼的争议焦点放在了债权人与相对人的权利义务上，相对忽视了债务人在代位权诉讼中所产生的问题，现有法律对债务人的权利义务规定也较为简略。而在代位权诉讼中，债务人作为两层法律关系的主体，是否需要参与诉讼，参诉的诉讼地位以及在代位权诉讼中是否具有当事人的诉讼权利义务等问题对代位权诉讼制度极为重要。所以本文将从债务人的视角研究代位权诉讼，分析现存问题并提供相关完善建议。通过分析我国的立法现状以及搜索相关司法案例，总结发现从债务人视角关注代位权诉讼主要存在以下四个问题：一为债务人在代位权诉讼中的诉讼地位如何确定；二是怎么规制与债务人有关的数个诉讼重复起诉的问题，即债权人提起代位权诉讼后又起诉债务人、债务人另行起诉相对人是否构成重复起诉，法院应当如何裁决；三为债务人的程序权利该如何救济；四为债务人签署的纠纷解决协议对代位权诉讼是否可以产生约束效力。对此，本文主要分为四个部分。第一部分为绪论，即本文的研究背景和意义、国内外研究现状以及研究方法和创新之处。第二部分为对代位权诉讼的简单概述，主要从代位权诉讼的概念与特征，比较分析典型国家和地区的代位权诉讼制度模式，以及从债务人视角讨论代位权诉讼的独特价值展开论述。第三个部分是列举债务人视角下我国代位权诉讼的不足。结合中国裁判文书网，从债务人的诉讼地位、关联诉讼的重复起诉问题、程序权利救济以及债务人签署的管辖、仲裁协议对代位权诉讼的适用效力等方面总结代位权诉讼中所存在的不足之处。第四个部分是对我国代位权诉讼的丰富完善。首先，对债务人的诉讼地位进行设定分析，得出在代位权诉讼中债务人的诉讼地位具有双重性，既可以列为无独立请求权的第三人，也可以作为证人出庭作证，但在同一诉讼中债务人的诉讼地位是唯一的，即只能在证人和无独立请求权的第三人之间择其一；其次，分情况对关联诉讼的重复起诉问题进行回应，无论是债权人既起诉相对人又起诉债务人的情形，还是代位权诉讼后，债务人另行起诉相对人的情形，本文均认为不构成重复起诉；然后，充分保障债务人程序救济权利，规定债务人在代位权诉讼中可以通过上诉以及申请再审的方式进行权利救济；最后，明确债务人签署的管辖协议及仲裁协议对代位权诉讼的适用效力，分析得出债务人签署的纠纷解决协议对代位权诉讼不应产生约束力。

The creditor's subrogation right system involves three parties and two layers of legal relations. Because of its complexity different from ordinary litigation, many controversial issues have arisen in the application of judicial practice. Many scholars in the past focused on the rights and obligations of creditors and counterparties in subrogation lawsuits, relatively neglecting the issues arising from debtors in subrogation lawsuits. The existing laws also provide relatively brief provisions on the rights and obligations of debtors. However, in the subrogation lawsuit, the debtor is the subject of two layers of legal relations. Whether he needs to participate in the lawsuit, his status in the lawsuit, and whether he has the rights and obligations of the parties in the subrogation lawsuit are extremely important issues for the subrogation lawsuit system. Therefore, this article will study the subrogation lawsuit from the perspective of the debtor, analyze the existing problems, and provide relevant suggestions for improvement.By analyzing the current legislative situation in China and searching for relevant judicial cases, it is found that there are four main issues in paying attention to subrogation litigation from the perspective of debtors:In a subrogation suit, How to determine the litigation status of the debtor; How to regulate the issue of duplicate lawsuits related to debtors, how should the court decide whether it constitutes a duplicate lawsuit if the creditor initiates a subrogation lawsuit and then sues the debtor, or if the debtor sues the counterparty separately; How to remedy the procedural rights of the debtor; Can the dispute resolution agreement signed by the debtor have binding effect on subrogation litigation.This article is mainly divided into four parts.The first part is the introduction, which includes the research significance, research methods, and innovation of this article. The second part is a brief overview of subrogation litigation, mainly focusing on the concept and characteristics of subrogation litigation, comparing and analyzing the subrogation litigation system models of typical countries and regions, and discussing the unique value of subrogation litigation from the perspective of debtors. The third part lists the shortcomings of subrogation litigation in China from the perspective of the debtor, and summarizes the shortcomings of subrogation litigation from the perspectives of the debtor's litigation status, the issue of duplicate prosecution in related litigation, procedural rights remedies, urisdiction signed by the debtor, and the effectiveness of arbitration agreements in subrogation litigation, combined with the China Judgment Document Network. The fourth part is the enrichment and improvement of subrogation litigation in China. Firstly, Analyzing the litigation status of the debtor, it is concluded that the debtor's litigation status in subrogation litigation has duality, which can be listed as a third party without independent claims, or as a witness to participate in litigation，But in the same lawsuit, the debtor's litigation status is unique. Secondly, respond to the issue of duplicate prosecution in related party litigation according to the situation, believing that the creditor suing the debtor after filing a subrogation lawsuit, and the debtor suing the counterparty separately, do not constitute duplicate prosecution. Then, fully protect the debtor's procedural relief rights and stipulate that the debtor can seek relief through appeal in subrogation litigation. Finally, It is clear that the jurisdiction agreement and arbitration agreement signed by the debtor are applicable to the action of subrogation，and analyze that the dispute resolution agreement signed by the debtor should not be binding on subrogation litigation.
