Abstract: The writer of this paper states that in the minds of some Chinese translation theorists there exists Nida’s Informational Translation Theory.The writer points out that Nida only uses the term of “message” in his works,which is far enough to develop a theory on “message”.Compared with traditional theory,Nida’s theory is only developed in the use of modern terms;the essence is just the same as the traditional theory.While Information Theory of Claude E.Shannon  aims at transmitting information,Nida’s Translation Theory aims at  transforming information.Transmitting information is different from transforming information.In the paper,the writer explains in detail the meaning of“message” in Nida’s theory.

Key words:  , Nida, translation theory, multi-dimension, reflection, non-existence, theory of information translation
