The move identification of the present study followed the four-move model of V. K. Bhatia who is the representative personage of ESP. It is composed of four moves (1993):Introducing purpose, Describing methodology, Summarizing results and Presenting conclusions. According to the above theory, Principles of the scientific method of sampling suggested by Nwogu (1997:121) as to the selection of joal were adopted in the study—representativity, reputation, accessibility. The focus is the analysis of move structures of abstract sections of them and contrastive studies between Economics and Humanities&Social Sci-ences of Lanzhou Jiaotong University in different moves of abstract sections. We find there are some similarities and differences between them. In general, the abstracts of Humanities &Social Sciences are more standard than Economics, which suggested English abstract sections of some Economics bachelors degree thesis need to be improved.
