Objective/Meaning Exploring the impact and paths of digital economy development of RCEP members on the dual margins of China's agricultural exports is of great significance for promoting the agricultural cooperation among RCEP members and enhancing the high-quality development of China's agricultural exports.

Methods/Procedures An indicator system is established from the perspectives of digital infrastructure construction, digital technology external competition, digital economy innovation environment, and digital application to measure the development level of digital economy. The H-K method is used to calculate the dual margins (intensive margin and extensive margin) of China's agricultural exports to other RCEP member countries, and multiple regression analysis is conducted to examine the impact of digital economy development on the dual margins of China's agricultural exports.

Results/Conclusions The development of China's digital economy is growing rapidly with a leading position. In agricultural exports to other RCEP member countries, the intensive margin shows relatively large changes with prominent differences among countries, while the extensive margin is generally at a high level with relatively small changes. The development of China's digital economy exerts a promoting effect on both dimensions of the dual margins of China's agricultural product exports, while the digital economy development level of other RCEP member countries plays an inhibitory role on the extensive margin. This impact has national as well as product heterogeneous effects, and trade costs and trade fluctuations play a regulatory role in the impact process. It is necessary to strengthen the role of the digital economy in promoting agricultural trade to improve the quality of agricultural economy, adopt differentiated strategies to expand export markets so as to achieve win-win cooperation, and to appropriately respond to trade costs and fluctuations to ensure agricultural trade.
