China''s new energy vehicle industry has entered the market-oriented stage,and RCEP members will become an important incremental market for China''s new energy vehicle exports.This paper examines the factors influencing China''s exports of new energy vehicles to RCEP members and analyzes the efficiency and potential of this trade.Panel data on China''s exports of new energy vehicles to RCEP members from 2012 to 2021 are used, and a gravity model and trade inefficiency model are employed to estimate China''s export efficiency and potential to RCEP members.The results show that the economic size of RCEP members, the population size of both parties, and a common language have a positive impact on China''s exports of new energy vehicles.Improvements in container shipping connectivity, government regulatory quality,and non-tariff measures also contribute to increased trade efficiency.China''s export efficiency of new energy vehicles to RCEP members has been increasing over the years,but there is heterogeneity among members,with higher export efficiency to members such as Vietnam,Korea,Thailand, and the Philippines;RCEP members with great potential for China''s new energy vehicle trade are developed economies such as Japan,New Zealand,and Australia.
