摘要： 请求权概念的创造是民法从诉讼秩序到权利秩序演进的需要。“请求权”经历了从救济性手段到建构性基石的转变，其从具体的权利扩展为抽象的概念，不但有助于民法的体系化，更促成了以实体权利为中心的法律维护模式的建立。但在多种意义上不加区分地使用请求权概念，模糊了相对权与相对法律关系，导致了责任法与时效法的结构性缺陷，并在一定程度上误导了诉讼标的理论。因此，应重新定位请求权的性质与功能，重新分析与梳理其相关理论，以淳化以法律关系为核心对象的私法体系。

Abstract: The creation of the concept of Claim (Anspruch) was rooted in the needs aroused by Civil Law's progress from theorder based on litigation to the order based on right system. “Claim” experienced the transition from as a remedy tool toas a constructive cornerstone, from a specific type of rights to an abstract concept, assisting civil laws' codification, and helping the law system focus on substantive rights. But the universal use of Claim in a variety of circumstances results inambiguity of the distinction between relative right and absolute right, leads to imperfection of rules on Liability and Limi-tation of Actions, as well as misguides the theory on litigation object to some extent. Thus Claim-related theories shouldbe re-analyzed to define precisely the nature and function of Claim in an attempt to refine the legal-relation-based CivilLaw system.
