Recognition of the validity of administrative agreements in regional harmonization legislation

The rapid development of regional economic integration has brought unprecedented challenges to administrative governance across different jurisdictions. This paper explores the validity determination of administrative agreements within regional collaborative legislation frameworks, focusing on the Yangtze River Delta, Chengdu-Chongqing Economic Circle, and Yellow River Basin. By integrating administrative law principles with regional legislative mechanisms, we develop a comprehensive analytical model for validity assessment, represented as (E=f(L,R,C)), incorporating legality (L), rationality (R), and contractual nature (C). Empirical analysis of 157 judicial decisions from 2019-2024 reveals that our model significantly improves consistency and efficiency in validity determinations, reducing regional disparities by 37.4% and processing times by up to 32%. This study highlights the importance of standardized validity criteria and adaptive regional mechanisms in enhancing judicial consistency and supporting effective cross-jurisdictional governance. Our findings suggest that dynamic adjustment and quantitative assessment frameworks can provide robust solutions to the challenges of regional collaborative legislation, ensuring both legal uniformity and local governance adaptability.
