Abstract: Studies on State Translation, deepened and expanded in recent scholarship, have embraced key sub-topics concerning state translation program, state translation capacity and state translation institution, covering state-related issues regarding state translation values.Research on State Translation as a new domain is proved fertile by previous explorations, and requires further in-depth analysis.Against this backdrop, Chinese scholars have proposed to develop State Translation Studies (STS) into a new discipline.Concept definition and theoretical explorations naturally lead to disciplinary construction.This paper attempts to clarify the rationale for constructing State Translation Studies into a discipline and justify the objectivity, necessity and rationality of such efforts.To integrate studies on State translation so as to develop relevant studies into a new discipline is an academic target that is worthwhile, urgent and feasible.
