行政協議效力認定的公私法協動論

在行政協議效力認定的問題上，公法主導論暴露出局限性。該模式過度依賴行政行為規則的優先適用，忽略了民事法律行為規則的功能價值。這不僅削弱了法律適用的靈活性，而且低估了案件審理的複雜性。與之相對，公私法協動論以綜合性視角解決這些問題，推動公法與私法的有效互動，滿足行政性與契約性的動態特性，並實現不同規則之間的功能整合。在理論層面，它通過承認、利用和協調差異，建立行政行為規則和民事法律行為規則相互協作的基礎結構。在實踐層面，它提倡動態考察各審查模塊中行政性和契約性的要素組合，深入探討如何使不同規則形成交互支持秩序，以提高裁判質量和平衡不同利益。公私法協動論應當取代公法主導論，成為行政協議司法審查的主導思想，推進行政法學的現代化。

Regarding the issue of determining the validity of administrative contracts, the public lawdominant theory reveals its limitations. This approach overly relies on the preferential application of administrative law rules, neglecting the functional value of civil legal rules. The result not only weakens the flexibility of legal application but also underestimates the complexity of case adjudication. In contrast, the theory of public-private law synergy addresses these issues from a comprehensive perspective, promoting effective interaction between public and private law to accommodate the dynamic nature of administrative and contractual elements, and to achieve functional integration between different sets of rules. At the theoretical level, it establishes a foundational structure for collaboration between administrative and civil legal rules by recognizing, utilizing, and coordinating their differences. At the practical level, it advocates for a dynamic examination of the combination of administrative and contractual elements in various review modules, delving into how different rules can form an interactive and supportive order to improve adjudication quality and balance competing interests. The theory of public-private law synergy should replace the public law-dominant theory as the guiding principle for judicial review of administrative contracts, thereby advancing the modernization of administrative law.
