This paper discusses the contents of the design science, and two kinds of design science models from the academic perspective. In view of some problems in the Chinese design domain, a novel digital model-based design science paradigm is proposed from the industrial perspective. It is suggested that the design science should include four research fields:(1) how to represent the design knowledge with a digital model; (2) the standard of the digital model; (3) the mechanism of the digital model-based knowledge flow; (4) how to integrate the digital model.
