China is the world's largest producer of vegetables,with vegetables being the primary export category of Chinese agricultural products,accounting for 16.157% of agricultural exports in 2022.In the context of the RCEP agreement's signing and implementation,it is highly significant to explore the status and potential of China's vegetable trade with its partners to deepen the positive effects of exports and enhance the international competitiveness of Chinese vegetables.The study utilizes panel data of China's vegetable export trade to RCEP partners from 2006 to 2022,constructs a stochastic frontier gravity model and a trade inefficiency model,empirically analyzes China's trade efficiency and its influencing factors with respect to RCEP partners,and measures the export potential of each country.The results indicate that the economic level,population size,economic disparity,vegetable yields,and trade environment of China and RCEP partners significantly impact vegetable exports.The rule of law,economic institutional environment,and infrastructure level of RCEP partners positively influence the efficiency of vegetable exports.However,the level of integrity in export destinations and improvements in government efficiency,conversely,negatively affect trade efficiency.The average efficiency of China's vegetable exports to RCEP partners over the years is 0.667,though there are significant differences among the countries within the RCEP partnership.China should continue to enhance the quality of its vegetable exports,expedite the implementation of the RCEP agreement,and further expand the depth and breadth of its cooperation with RCEP partners to reduce trade resistance and promote the continued growth of vegetable export volumes.
