The growing need to improve the quality and efficiency of translation by using technology has stimulated the practice of and research into translation technology teaching (TTT). Naturally, there is a need to analyse the state of the art and development of TTT from a quantitative perspective, because such research is still very scarce. This paper uses the bibliometric technologies, CiteSpace and VOSviewer in particular, to delineate the publication information of TTT-related research mainly in two citation databases, i.e., Web of Science (WoS) and China National Knowledge Infrastructure (CNKI), from the year 1999 to 2020. It finds that China is gaining importance in TTT-related research, that international English-language publications pay more attention to the teaching of MTPE, while Chinese-language publications focus more on corpus-based TTT, and that English publications tend to use empirical methods, while Chinese publications tend to adopt non-empirical methods. The differences between the two publication communities in research methods and focuses call for contact and exchange between the two communities.
