Abstract: Translational ethics of commitment develops on the foundation of traditional translational ethics including ethics of representation, ethics of service, ethics of communication and norm-based ethics. Theoretically supported by communicative ethics,translational ethics of commitment integrates all the ethical values held by various schools of traditional translational ethics and elaborates translational ethics on the macro-level. Not only does it explicate the responsibilities that translators should take in the process of translation, but also it clearly points out the field to which it can be applied. Besides, it equally treats all the agents to translation. All these make it a transcendence of traditional translational ethics.
