Study on the Quality of Human and Machine Translation of The Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area

This study is grounded in the theory of functional equivalence and selects the Outline of the Development Plan for the Guangdong-Hong Kong-Macau Greater Bay Area as a case study. It aims to explore the quality assessment of government document translation between human and machine translation. By delving into the three dimensions of vocabulary, pragmatics, and culture as they relate to functional equivalence theory, this research explores the performance of human and machine translation in handling specific types of texts such as government documents. The study reveals that despite of advancements in machine translation, it still has limitations in dealing with complex semantic structures, cultural contexts, and specialized terminology. Human translation offers advantages in accurately conveying semantics, managing cultural differences, and defining specialized terminology. The paper proposes effective solutions to enhance the accuracy and readability of machine translation in practices, emphasizing the importance of translation quality in conveying accuracy in government documents, promoting international communication, government document as well as enhancing regional economic prosperity.
