摘 要
民事法律行为效力认定是民法理论与司法实践中的核心议题，随着市场经济的发展和法治建设的推进，各类新型民事活动不断涌现，对传统法律行为效力理论提出挑战。本研究旨在通过对我国现行民事立法及司法解释的系统梳理，结合最高人民法院指导案例及典型判例分析，探讨民事法律行为效力认定的司法适用标准及其发展演变。研究采用规范分析与实证研究相结合的方法，以2017-2022年期间全国各级法院相关判决为样本，运用统计分析、文本分析等手段，揭示当前司法实践中存在的主要问题及成因。研究发现，在合同效力、意思表示瑕疵、代理权行使等方面存在裁判尺度不统一现象，部分新型交易模式下的法律行为效力认定缺乏明确依据。

Abstract
The determination of the effectiveness of civil legal acts is the core issue in the civil law theory and judicial practice. With the development of market economy and the promotion of the rule of law construction, all kinds of new civil activities emerge constantly, challenging the traditional theory of the effectiveness of legal acts. This study aims to explore the judicial application standards and evolution of the effectiveness of civil legal acts through the systematic review of the current civil legislation and judicial interpretation in China, combined with the analysis of the guiding cases and typical cases of the Supreme People's Court. The research adopts the method of combining normative analysis and empirical research, taking the relevant judgments of courts at all levels across the country from 2017 to 2022 as samples, and uses statistical analysis, text analysis and other means to reveal the main problems and causes in the current judicial practice. It is found that there is a inconsistency in the aspects of contract validity, defects of intention ex pression and exercise of agency, and there is a lack of clear basis for the identification of the effectiveness of legal acts under some new transaction modes.
