Limitations of ChatGPT in Chinese-to-English News Translation: A Functional Equivalence Perspective
This study evaluates ChatGPT's capability in Chinese-to-English news translation through a functional equivalence lens. Comparing GPT-4o outputs with official translations, a detailed error analysis reveals that while ChatGPT excels in fluency and basic information transfer, it struggles significantly with nuanced areas such as proper noun consistency, complex sentence structures, coherent discourse flow, and maintaining a journalistic tone. These limitations impact communicative effect and reader trust, underscoring the critical need for human oversight in high-stakes news translation. The findings advocate for human-AI collaboration and highlight functional equivalence as a robust framework for assessing AI-generated content.

Challenges in Terminology & Proper Nouns
ChatGPT frequently struggles with accurate and consistent translation of proper nouns and policy terms. For instance, 'Mei Guo Zheng Fu' was rendered as 'the US government' instead of the official 'the White House', blurring authority. Similarly, 'Chong Jian Geng Hao Wei Lai' Fa An' was translated as 'Build Back Better Act' instead of 'Build Back Better Agenda', misrepresenting a policy's legal status. Inconsistent acronym use also reduced clarity, highlighting a lack of specialized reference materials and style guide adherence.
Sentence Structure & Grammatical Cohesion
ChatGPT's translations tend to mirror Chinese clause order literally, resulting in English prose that lacks natural flow and grammatical cohesion. While individually fluent, complex multi-clause Chinese sentences are often rendered as run-ons or fragmented phrases in English, demanding extra effort from the reader. This leads to an irregular sentence structure that compromises the seamless narrative expected in professional news reporting.
Maintaining Coherent Discourse Flow
The model shows limitations in maintaining coherent discourse flow. It often underuses or misplaces transition markers (e.g., 'however', 'moreover'), leading to disjointed paragraphs. In an example, principles of the 'Global Civilisation Initiative' were rendered as a pseudo-bulleted list, losing the integrated narrative flow of the original. This omission of logical connectives makes ideas build less effectively, impacting overall comprehension.
Gaps in Tone & Journalistic Style
ChatGPT's output frequently diverges from the balanced and journalistic register of official news, leaning towards a didactic or casual tone. Metaphors are often replaced with plainer language, reducing rhetorical resonance. The model sometimes uses direct address, imperatives, and colloquial fillers, clashing with the objective, third-person distance typical of news. Disrupted stylistic conventions (e.g., title-case for headings, exclamation points) and a tendency for categorical statements over cautious hedging further compromise the authoritative tone and reader trust.

Case Study: Semantic Drift in Political Terminology
The study highlights how ChatGPT translated 'Mei Guo Zheng Fu' (US government) as 'the US government' instead of the officially preferred 'the White House'. While literally accurate, 'the White House' specifically refers to the President's office and policy announcements, whereas 'the US government' can imply any branch of federal administration. This subtle lexical choice can blur the source of authority and potentially mislead readers regarding who is speaking or deciding. This demonstrates a key challenge in achieving true functional equivalence beyond mere linguistic correctness.
