代理授权行为是整个代理制度的核心,而授权行为的性质问题更是核心中的核心。代理授权行为是否具有无因性直接决定着基础法律关系的变动能否对授权行为产生影响。本文通过分析无因性理论下三方的利益格局及其与表见代理制度替代的可能性,提出了我国应采取的立法范式。 Agency authorization behavior is the core of the entire agency system, and the nature of the authorization behavior is the core of the core. Whether the agent’s authorization behavior has no cause directly determines whether the change of the basic legal relationship can have an impact on the authorization behavior. In this paper, we analyze the tripartite interest pattern under the non-causal theory and the possibility of substitution with the surrogate agency system, and put forward the legislative paradigm that China should adopt.
