The signing of RCEP (Regional Comprehensive Economic Partnership) elevates East Asian regional economic integration and agricultural trade liberalization to new heights. This paper comprehensively evaluates the trade facilitation levels of RCEP member states. By incorporating trade facilitation as a term of trade inefficiency into a random frontier gravity model, it measures the efficiency of China’s aquatic product exports and concludes that: The economic scale of importing countries, the complementarity of bilateral aquatic products trade, and shared languages significantly promote China’s aquatic products exports, while China’s economic scale and distance act as barriers to such exports; The average efficiency of China’s aquatic products exports to RCEP member countries is approximately 0.55, indicating substantial untapped export potential and room for improvement; Enhancing trade facilitation levels is key to boosting future trade efficiency.
