Under the background of the construction of free trade zone

the business and economic exchanges between Hainan and other countries around the world will be strengthened

and the transnational business cooperation will be increased. In this condition

the gap of business English translation talents is bound to increase. Therefore

we should pay more attention to business English translation. Under the guideline of functional equivalence theory

this paper analyses Business English from three levels: syntactic equivalence

textual equivalence

and stylistic equivalence. This paper also explores the practical value of the theory in business English translation

and provides the idea and method for business English translation

offering reference for developing applied English translation talents for the construction of Hainan free trade zone.
