談到拍賣，多數相關的研究著重於競標策略或競標行為，而競標流程並非研究主流。本篇研究以四名國際拍賣行的拍賣官為例。研究者以多模態方法、語料庫分析，及元功能來探討這些拍賣官的手勢與用語，去研究拍賣官如何透過口語和非口語溝通來進行拍賣。研究結果指出，在競標期間拍賣官經常採用指涉手勢和展演手勢。功能詞AT、YOU、THE、IT和IN，以及實詞HERE、THANK、BID、NOW和GIVE頻繁出現在拍賣官的用語中。以元功能的角度而言，拍賣官與競標者之間的互動實現了人際元功能；競標活動的參與者、流程和情形闡釋了概念元功能；整個拍賣可被視為語篇元功能的動態呈現。本研究可提供實用的資訊給想參與拍賣活動或進行手勢和用語相關研究的人士。

With regard to the auction, most of the relevant research is about bidding strategies or bidding behavior. The research on the bidding process is not the main stream. This study used four auctioneers at international auction houses as an example. The researcher examined the gestures and speech of the auctioneers on the basis of multimodal approach, corpus analysis, and metafunctions to explore how auctioneers conducted live auctions with verbal and nonverbal communication simultaneously. The results indicate that auctioneers usually adopted referential gestures and performative gestures during the bidding. The function words, AT, YOU, THE, IT, and IN, and the content words, HERE, THANK, BID, NOW, and GIVE, high frequently existed in the speech of auctioneers. In the aspect of metafunctions, the interaction between auctioneers and bidders realized interpersonal metafuctions. The participants, the process, and the situation of the bidding activity interpreted ideational metafunctions. The whole auction event could be regarded as the dynamic presentation of textual metafunctions. To those who would like to engage in auction events or conduct relevant research on gestures and speech, this study can provide useful information.
