As one of a serial of reports, this paper is a survey on multimedia researches and applications in China, 2001. Since multimedia is a cross research area, papers about multimedia technology are distributed on various journals. We saw about 2 472 papers published on 9 Chinese journals in 2001, from which we selected 394 ones on multimedia technology and application, then we made analyses on them, and the classified data were compared with that of 1998, 1999 and 2000. Looking into the data we can see that researchers in China pay more and more attention at digital watermarking, virtual reality, multimodal interface, multimedia data retrieval technology, distributed multimedia supporting technology, GIS and Digital Earth, which are also the international evolution trends in a quite long period. We present here an overview on the progress in multimedia technology in China, 2001. This will be convenient for researchers looking up references, and helpful for editors compiling journals and for authors contributing papers.
