Translation competence has been a heated topic in recent years. Yet, business English majors (BEMs), as non-translation bilingual majors, also need training in translation competence. The paper intends to construct translation competence for BEMs through four modules: schema based on business knowledge; information types; cognitive thinking and post-editing based on machine translation. By integrating these four modules, the translation competence can be improved in a relatively short teaching time for BEMs. [The paper is one of the achievements of Innovative Projects of Colleges and Universities under the Department of Education of Guangdong Province in 2019 "On the modularized construction of Translation competence for Business English Majors Driven by Machine Translation" (Project number: 2019WTSCX024).]
