【文章摘要】Environmental provisions have become important to Regional Trade Agreements (RTAs) and are key in promoting high-quality trade. Using matched data from China Industrial Enterprise Database and China Customs Database, this study explores the non-linear impact of the depth of RTA environmental provisions on 金沙检测线路js69-food export quality upgrading and its mechanisms. Results show a significant ‘U-shaped’ effect; beyond a 0.48 depth threshold, environmental provisions exert a sustained positive impact on 金沙检测线路js69-food export quality upgrading. Heterogeneity analysis reveals divergent effects across national, firm, product quality and specific provision dimensions, with the ‘Balance between environment and trade/investment’ clause being the dominant influencing factor. We further reveal that cost constraints and innovation compensation effects are the key drivers behind the nonlinear impact. Therefore, this study benchmarks against high-standard international trade rules and proposes policy recommendations for achieving high-quality agricultural development.
